TYPE 241-LED: FeiChun’s Flagship AS/NZS 1802 Certified Self-Powered LED Illuminated Mining Cable for Continuous Miners, Longwall Shearers & Underground Coal Production — Complete Technical Guide to the World’s Most Versatile Illuminated Coal Mining Cable (1.1 kV – 22 kV, 45 Part Numbers, FC-TPU™ C-Series CM/Longwall Grade Crushing-Resistant Sheath, Dual FC-EMH™ / FC-CVD™ Energy Harvesting)
Comprehensive professional guide to the TYPE 241-LED — FeiChun’s flagship illuminated mining cable and the most versatile LED-equipped cable certified to AS/NZS 1802:2003 for underground coal mining. With 45 part numbers spanning 1.1 kV through 22 kV, the TYPE 241-LED covers virtually every underground coal feeder and trailing application: continuous miner trailing cables, longwall shearer power feeders, AFC drive feeders, BSL feeders, panel pump cables, and mobile substation HV incoming supply — all with self-powered LED visibility that requires no external DC supplies, no gate end box modifications, and no coupler changes. Where FeiChun’s TYPE 275-LED serves shuttle-car reeling duty and the TYPE 260-LED serves armoured feeder duty, the TYPE 241-LED is the workhorse general-purpose illuminated cable for continuous miners and longwall systems — the machines that do the actual cutting and haulage at the coalface. The proprietary FC-TPU™ C-Series sheath (Formula FC-2026-TPU-C1) is specifically formulated for the crushing loads continuous miners and shuttle cars impose when they run over trailing feeders. The semi-conductive elastomeric screen is magnetically transparent, giving the FC-EMH™ induction system 15–20% higher coupling efficiency than braid-screened cables — critical for maintaining reliable LED illumination at partial continuous-miner load or longwall shearer idle. This article covers cable construction, dual energy harvesting architecture, FC-TPU™ C-Series crushing-resistant sheath, four-layer surge protection, complete dimensional and electrical data across all five voltage classes, full standards compliance including QLD CMSH Act and NSW WHS (Mines) Regulation, application scenarios for continuous miners and longwall systems, product selection versus the TYPE 260-LED and TYPE 275-LED, and direct factory procurement from Anhui Feichun Special Cable Co., Ltd.

💡 The Flagship: Why the TYPE 241-LED Is the #1 Illuminated Cable for Australian Underground Coal
If you work underground in an Australian coal mine — whether you’re a sparky, a deputy, a CM operator, or a mine manager — there’s a fair chance the most common cable on your mine site is a Type 241. It’s the universal workhorse of the underground coal industry. The Type 241 is a general-purpose flexible feeder cable designed for continuous miners, longwall systems, and any underground coal application requiring mechanical strength and crushing resistance. It’s not a specialised shuttle-car reeling cable (that’s the Type 275), and it’s not an armoured cable for gate-road feeders (that’s the Type 260). It’s the cable that does everything else — and in underground coal mining, “everything else” covers a massive range of equipment from the 1.1 kV panel pump all the way up to the 22 kV mobile substation incoming supply.
That’s why FeiChun chose the Type 241 platform as the flagship for its illuminated mining cable range. With 45 part numbers spanning five voltage classes (1.1 kV, 3.3 kV, 6.6 kV, 11 kV, and 22 kV), the TYPE 241-LED covers more underground coal applications than any other illuminated cable in the world. Continuous miner trailing cables at 1.1–3.3 kV. Longwall shearer power feeders at 3.3–11 kV. AFC and BSL feeders at 3.3–6.6 kV. Panel pump feeders at 1.1 kV. Mobile substation HV cables at 11–22 kV. If it’s a flexible feeder or trailing cable in an underground coal mine, there’s a TYPE 241-LED for it.
And here’s the critical detail: every single one of those 45 part numbers is certified to AS/NZS 1802:2003 — the mandatory standard for underground coal mining cables in Queensland, New South Wales, and New Zealand. This is not a general-mining cable rebadged with a coal mine sticker. The TYPE 241-LED incorporates all the AS/NZS 1802-specific requirements — semi-conductive elastomeric screen, semi-conductive PCP insulated earth cores, extensible pilot conductor, enhanced flame-propagation performance, and methane-atmosphere intrinsic safety compliance — that make it legal and safe for underground coal mine service.
FeiChun designates the TYPE 241-LED as its flagship illuminated mining cable for three reasons: (1) broadest voltage range (1.1–22 kV — no other AS/NZS 1802 LED cable reaches 22 kV), (2) broadest application range (CM, longwall, AFC, pumps, mobile substations), and (3) the magnetically transparent semi-conductive screen that delivers 15–20% higher FC-EMH™ induction efficiency than any braid-screened alternative. If you’re speccing one LED cable platform for an entire underground coal operation, the TYPE 241-LED is the one that covers the most ground.
Cables used in underground coal mines in Queensland and New South Wales must be certified to AS/NZS 1802:2003. This is mandated by the QLD Coal Mining Safety and Health Act 1999 and the NSW Work Health and Safety (Mines) Regulation 2014. Using a general-mining cable certified only to AS/NZS 2802:2000 in an underground coal mine is a regulatory non-compliance that can result in prohibition notices from state mining inspectors. The TYPE 241-LED holds full AS/NZS 1802:2003 certification. No workarounds. No derogations. No dramas.
🔧 TYPE 241-LED Cable Construction: Layer-by-Layer Breakdown for Continuous Miner & Longwall Service
The TYPE 241-LED is built on the proven Type 241 flexible feeder platform — the most widely used underground coal cable construction in Australia. The cable incorporates all the AS/NZS 1802-specific construction features that distinguish underground coal cables from general-mining cables, including the semi-conductive elastomeric screen, semi-conductive PCP insulated earth cores, and extensible pilot conductor.
1. Conductors: Annealed tinned copper, flexible Class 5 stranding per AS/NZS 1125. Available from 6 mm² (1.1 kV) through to 150 mm² (6.6 kV) and 95 mm² (11 kV / 22 kV). Tinning provides corrosion resistance in the wet underground coal environment — and any underground coal electrician will tell you, everything underground is wet.
2. Insulation: Ethylene Propylene Rubber (EPR) per AS/NZS 1802:2003, Cl. 4.4. EPR is the gold standard for underground coal cable insulation — superior moisture-treeing resistance, excellent electrical properties at elevated temperatures, and the flexibility needed for trailing and reeling duty behind continuous miners.
3. Core Screening — Semi-Conductive Elastomeric Screen: This is a critical differentiator. The TYPE 241-LED uses a semi-conductive elastomeric screen over each phase core — not a composite copper/polyester braid screen like the Type 409 or Type 440. This screen is magnetically transparent — it passes magnetic flux with near-zero attenuation. For the FC-EMH™ induction energy harvesting system, this translates directly to 15–20% higher coupling efficiency compared to braid-screened constructions. That means more reliable LED illumination at lower load currents — exactly what you need when a continuous miner is idling between cuts or a longwall shearer is repositioning.
4. Earth Cores — Semi-Conductive PCP Insulated: Semi-conductive PCP (polychloroprene) insulated interstitial earth conductors. The semi-conductive insulation on the earth cores is an AS/NZS 1802-specific requirement — it enhances earth-fault loop impedance performance and ensures reliable operation of the mine’s earth-leakage protection relay system. This is safety-critical in a methane atmosphere.
5. Pilot Core — EPR Insulated Extensible: EPR insulated extensible pilot conductor (0.75 mm² for 6–25 mm² variants; 1.25 mm² for 35+ mm² variants). The extensible construction accommodates cable stretching during trailing and reeling duty without pilot circuit breakage. Pilot loop continuity monitoring is mandatory under AS/NZS 1802 — any break triggers immediate disconnection.
6. Filler — Semi-Conductive Elastomeric: Semi-conductive elastomeric filler in the cable interstices, maintaining cable geometry under the dynamic bending and crushing loads of continuous-miner and longwall service. The FC-CVD™ or FC-EMH™ module is integrated within this layer.
7. Energy Harvesting Module: FeiChun® FC-CVD™ (1.1 kV) or FC-EMH™ (≥ 3.3 kV). Both C-variants include enhanced energy-storage capacitor banks optimised for the variable-load profiles of continuous miners and longwall shearers.
8. LED Strip: Industrial-grade flexible LED strip, warning red (620–630 nm), silicone encapsulated. Full-length illumination providing 360° visibility through the translucent outer sheath.
9. FC-ASB™ Aramid Stress-Relief Braid: FeiChun® woven aramid (Kevlar) braid surrounding the LED FPC circuits. Isolates the LED circuit from mechanical stress — the cable can be trailed across the mine floor, bent around equipment, driven over by shuttle cars, and coiled on cable reels without any stress reaching the LED circuit.
10. Textile Reinforcement: Open-weave textile reinforcement layer — provides additional mechanical support and controls cable geometry during the dynamic bending and crushing loads inherent in continuous-miner trailing and longwall feeder service.
11. Outer Sheath: Heavy duty translucent FR-TPU — FeiChun® FC-TPU™ C-Series, CM/Longwall Grade (Formula FC-2026-TPU-C1). Specifically formulated for the crushing loads of continuous-miner and longwall environments. Enhanced compressive modulus distributes point loads across the LED strip, preventing damage when machinery runs over the cable. 3–5× abrasion resistance versus conventional mining-grade elastomer. Halogen-free, flame-retardant, self-extinguishing.
🔬 The Magnetically Transparent Screen Advantage: 15–20% Higher FC-EMH™ Induction Efficiency
This is one of the most important technical details in the entire TYPE 241-LED story — and it’s the reason FeiChun chose this platform as its flagship. The TYPE 241-LED’s semi-conductive elastomeric screen is magnetically transparent. This sounds like an engineering footnote, but for the FC-EMH™ electromagnetic induction system, it’s a game-changer.
In a standard braid-screened cable construction — like the Type 409 or Type 440 — the core screen is a composite copper/polyester braid. Copper is an excellent electrical conductor, but it also interacts with alternating magnetic fields. When the FC-EMH™ pickup coil tries to harvest energy from the magnetic field generated by the phase conductors, the copper braid screen partially shields and redirects some of that magnetic flux. The coil still works — FeiChun’s engineering accounts for this — but a proportion of the available magnetic energy is lost to the braid before it reaches the pickup coil.
The TYPE 241-LED doesn’t have this problem. Its semi-conductive elastomeric screen fulfils all the electrical screening requirements of AS/NZS 1802:2003 — uniform electric field distribution, partial discharge suppression, earth-fault detection sensitivity — but it is magnetically transparent. The magnetic flux from the phase conductors passes through the screen with near-zero attenuation and arrives at the FC-EMH™ pickup coil at essentially full strength.
FeiChun quantifies this advantage as 15–20% higher coupling efficiency compared to braid-screened constructions. In practical terms, this means the TYPE 241-LED’s LED system produces reliable, full-brightness illumination at lower load currents than a braid-screened LED cable would. For continuous miners that cycle between cutting, tramming, and idle — spending significant time at partial load — this efficiency margin is the difference between rock-solid LED illumination and marginal performance at low load. For longwall shearers repositioning between cutting passes, the same principle applies.
Continuous Miner at Idle: A CM sitting idle between cuts still draws some load (hydraulics, cooling, conveyor standby). With a braid-screened cable, this low load might produce marginal LED brightness. With the TYPE 241-LED’s magnetically transparent screen, the FC-EMH™ system harvests 15–20% more energy from the same magnetic field — keeping LED brightness solid even during idle periods.
Longwall Shearer Repositioning: Between cutting passes, the shearer draws reduced current as it repositions on the face. The TYPE 241-LED maintains full LED brightness throughout the repositioning cycle — no dimming, no flickering, no break in visibility.
Panel Pump at Steady Low Load: Small panel pumps at 1.1 kV draw modest current. While the 1.1 kV variants use FC-CVD™ (capacitive, not inductive), the same non-metallic screen construction benefits the cable’s overall flexibility and installation handling.
⚡ Dual Energy Harvesting: FC-CVD™ (1.1 kV) + FC-EMH™ (3.3–22 kV) — Optimised for CM & Longwall Duty
The TYPE 241-LED spans the full voltage range of underground coal production equipment — from 1.1 kV panel pumps to 22 kV mobile substation incoming supply. This requires FeiChun’s dual energy harvesting architecture: FC-CVD™ for the low-voltage variants and FC-EMH™ for everything at 3.3 kV and above.
| Voltage Class | Harvesting | Operating Principle | CM/Longwall Optimisation |
|---|---|---|---|
| 1.1 kV | FC-CVD™ C | Capacitive voltage divider. High-impedance tap draws tens of milliamps. Onboard rectifier + LDO to 12 V DC. | Enhanced capacitor bank sized for CM load cycling (cutting → tramming → idle). Bridges low-load intervals without LED dimming. |
| 3.3 kV | FC-EMH™ C | Electromagnetic induction. Magnetically transparent SC screen gives 15–20% higher coupling vs braid-screened. | Enhanced energy-storage capacitor bank. Reliable LED at partial CM load. Flicker-free during tramming and idle. |
| 6.6 kV | FC-EMH™ C | Stronger source field. Ample harvesting margin. SC screen passes flux without attenuation. | Longwall shearer compatibility — wide input-voltage tracking accommodates full shearer drum-cutting duty cycle. |
| 11 kV | FC-EMH™ C | Maximum coupling efficiency. Comfortable energy margin under all load conditions. | Longwall shearer and mobile substation feeder. No brightness variation during load cycling. |
| 22 kV | FC-EMH™ C | Highest voltage class. Strongest available magnetic field. Maximum harvesting headroom. | Mobile substation HV incoming supply. Continuous LED at all load conditions including light-load standby. |
Both harvesting modes satisfy AS/NZS 60079.11 (intrinsic safety) and AS/NZS 3808 (Group I methane). The FC-EMH™ provides galvanic isolation — zero electrical connection between the HV power circuit and the low-voltage LED circuit. The FC-CVD™ uses capacitive limiting — inherent high-impedance restricts energy below IS thresholds. Both approaches ensure the LED circuit cannot ignite methane or coal dust under any fault condition.
Note: The “C-variant” designation on both FC-CVD™ and FC-EMH™ modules denotes the CM/Longwall-optimised version with enhanced energy-storage capacitor banks. This is distinct from the S-variant (shuttle-car optimised, used in the TYPE 275-LED) which is sized for the different load-cycling profile of shuttle cars. Both C and S variants use the same core technology — the capacitor bank sizing and control-loop tuning differ to match the specific load profile of the target equipment.
🛡️ FC-SPM™ Four-Layer Surge Protection: Handling CM & Shearer Motor Inrush Transients
Continuous miners and longwall shearers generate some of the most aggressive transient voltage spikes in underground coal mining. When a CM cutting head hits a hard band and the motor stalls momentarily before restarting, the inrush current can be 5–10× the rated current — and the accompanying voltage transient hammers everything on the circuit. Longwall shearers cutting through varying seam conditions generate similar transients as the drum motors cycle. The TYPE 241-LED’s FC-SPM™ module is a four-layer architecture designed to handle these transients without any degradation of the LED system.
| Layer | Component | Function & Operating Principle |
|---|---|---|
| Layer 1 | Magnetic Saturation | FeiChun® tuned coil enters saturation — caps energy at source (FC-EMH™ variants). Prevents the induction coil from delivering excessive energy during motor inrush events where current can spike to 5–10× rated. |
| Layer 2 | TVS Diodes | Picosecond clamping of transient voltage spikes. Handles CM cutting-head stall/restart transients and shearer drum motor inrush — the most aggressive transients in underground coal production. |
| Layer 3 | Zener / LDO Regulation | Precision regulation locks LED power rail to 12/24 V DC. Eliminates flicker during the rapid load cycling (cutting → tramming → idle) that defines continuous-miner and longwall shearer operation. |
| Layer 4 | PTC Resettable Fuses | Polymer PTC devices auto-reset after overcurrent events. Zero maintenance for full cable service life. Critical for cables that are sealed and inaccessible once deployed in a production panel. |
🔴 FC-TPU™ C-Series CM/Longwall Grade Sheath: Crushing Resistance Meets Light Transmission
Here’s the reality of continuous-miner and longwall operations in Australian underground coal: cables get run over. It’s not a question of “if” — it’s a question of “how often.” Continuous miners weigh 70–120 tonnes and tram over their own trailing cables. Shuttle cars cross CM trailing cables at roadway intersections dozens of times per shift. Longwall face equipment crushes feeder cables against the floor and powered supports. Any cable sheath that’s going to survive in this environment needs to handle extreme compressive point loads without cracking, delaminating, or losing its structural integrity.
For a standard Type 241, this is already a demanding requirement. For the TYPE 241-LED, it’s harder — because the sheath also needs to transmit light from the LED strip to the outside world. You can’t just make the sheath thicker and harder to resist crushing; that would reduce light transmission. And you can’t make it thinner and softer for better light transmission; the first run-over would destroy it. You need a compound that does both — and that’s exactly what FeiChun’s FC-TPU™ C-Series (CM/Longwall Grade, Formula FC-2026-TPU-C1) delivers.
| Property | Performance | Standard / Test Method |
|---|---|---|
| Crushing Resistance | Enhanced compressive modulus distributes point loads across the LED strip, preventing damage when continuous miners or shuttle cars run over trailing feeders. LED continues to operate after crushing events. | FeiChun proprietary crush testing, simulating CM and shuttle-car wheel loads |
| Light Transmittance | Clear, uniform transmission of 620–630 nm warning-red LED output through full sheath wall thickness. LED glow remains visible after repeated crushing and abrasion in service. | FeiChun proprietary optical testing |
| Abrasion Resistance | 3–5× conventional mining-grade elastomer. Resists gouging from coal fragments, roof bolts, conveyor chain, and continuous-miner track shoes. | Abrasion testing per AS/NZS 1802 |
| Flame Retardancy | Meets AS/NZS 1802:2003 Cl. 4.12 flame propagation requirements. Halogen-free; self-extinguishing; no toxic or corrosive fumes. | AS/NZS 1802:2003 Cl. 4.12 |
| Flex-Cycle Life | Rated for continuous-miner trailing/reeling duty — thousands of reel-in/reel-out cycles per panel without loss of light transmittance or mechanical integrity. | AS/NZS 1802:2003 bending test requirements |
FeiChun manufactures three distinct FC-TPU™ translucent sheath compounds: S2 (shuttle-car grade — TYPE 275-LED) optimises flex-cycle fatigue life for repetitive reeling; A3 (armour grade — TYPE 260-LED) optimises point-load resistance against steel armour wire tips; and C1 (CM/Longwall grade — TYPE 241-LED) optimises crushing resistance for the compressive loads continuous miners and shuttle cars impose when they run over cables. Specifying the wrong compound risks premature failure — an S2 shuttle-car sheath doesn’t have the compressive modulus to survive CM run-overs, and an A3 armour-grade sheath isn’t optimised for the abrasion pattern of coal fragments and track shoes. The C1 formula is purpose-built for the CM and longwall environment.
📐 Dimensional & Electrical Data: All 45 Part Numbers — 1.1 kV, 3.3 kV, 6.6 kV, 11 kV, 22 kV
The TYPE 241-LED offers 45 part numbers across five voltage classes — the broadest range of any AS/NZS 1802 illuminated cable. Part numbers use the MCU- prefix (underground coal series) per FeiChun convention. Weights are approximately 10–14% above standard Type 241 equivalents. The semi-conductive elastomer screen is magnetically transparent, enabling optimal FC-EMH™ coupling efficiency at all HV voltage classes.

🏆 Ten Key Operational Advantages: The Flagship Underground Coal LED Cable
1. FeiChun Flagship — #1 Illuminated Coal Mining Cable: 45 part numbers. Five voltage classes (1.1–22 kV). Covers continuous miners, longwall shearers, AFC drives, BSL feeders, panel pumps, and mobile substations. If you want one LED cable platform for your entire underground coal operation, this is the one.
2. Magnetically Transparent Screen — 15–20% Higher Induction Efficiency: The semi-conductive elastomeric screen passes magnetic flux with near-zero attenuation. FeiChun’s FC-EMH™ pickup coil achieves 15–20% higher coupling efficiency than in braid-screened cables — meaning rock-solid LED illumination even when the CM is idling between cuts or the shearer is repositioning. No other LED cable construction offers this advantage.
3. Plug-and-Play for CM & Longwall: No external DC supplies. No gate end box modifications. No coupler changes. No additional infrastructure. Direct drop-in replacement for standard Type 241. Disconnect → connect → energise → glow. Your sparkies can swap over during a normal shift without any special procedures.
4. Production Panel Visibility: Continuous red glow delineates feeder cable paths in production panels, gate roads, and longwall face entries. Your blokes can trace energised cables without portable lighting — critical during panel changeovers, cable splicing, and emergency evacuation. Visible from 30+ metres in total darkness.
5. Intrinsically Safe for Methane Atmospheres: Cold light source. Galvanic isolation (HV) or capacitive limiting (LV). AS/NZS 3808 and AS/NZS 60079.11 compliant for Group I (methane/coal dust) atmospheres. No sparks, no hot surfaces, no ignition risk — even in the gassiest conditions your mine throws up.
6. FC-TPU™ C-Series Crushing & Flex Durability: CM/Longwall grade translucent sheath with enhanced compressive modulus. Survives cable run-overs by continuous miners and shuttle cars — because in underground coal, cables get run over, and there’s no point pretending otherwise. 3–5× abrasion resistance vs conventional mining-grade elastomer.
7. Widest Voltage Range in AS/NZS 1802 Series: 1.1 kV through 22 kV on a single cable platform — the broadest voltage coverage of any AS/NZS 1802 illuminated cable in the world. From the smallest 1.1 kV panel pump to the 22 kV mobile substation incoming supply, one cable family does the lot.
8. Flicker-Free CM & Longwall Load Tracking: FC-CVD™ C-variant and FC-EMH™ C-variant include enhanced energy-storage capacitor banks that bridge low-load intervals during CM cutting cycles and longwall shearer duty. Completely flicker-free illumination throughout the entire production cycle. No dimming during tramming or idle.
9. Live Cable Indication & LOTO Safety: Immediate visual energisation status — glow means live, no glow means isolated. Critical for LOTO procedures in production panels where you’ve got CM cables, shearer cables, AFC feeders, and pump cables all running through the same gate road. No more tracing cables with a torch to figure out which one’s still got juice.
10. Full State Regulatory Compliance: QLD CMSH Act 1999. NSW WHS (Mines) Reg 2014. AS/NZS 1802 mandatory for underground coal. The TYPE 241-LED meets every requirement without derogation. No regulatory risk. No prohibition notices. Your SSE and mine manager can sign off with full confidence.
⛏️ Application Scenarios: Continuous Miners, Longwall Shearers, AFC Drives & Mobile Substations
Challenge: The continuous miner is the heart of a development panel. It cuts coal, loads it onto the shuttle car, trams to the next cut, and repeats — all while trailing 200–300 metres of power cable through the roadway behind it. The CM trailing cable is dragged over broken stone, driven over by shuttle cars at intersections, crushed against roof bolts, and wound onto cable reels hundreds of times per shift. In complete darkness, the CM cable is invisible to everyone except the CM operator — shuttle car drivers crossing the cable at intersections can’t see it, and personnel on foot navigating through the panel rely on cap-lamp visibility to avoid the cable. Cable run-overs are among the most common and costly electrical incidents in underground coal development panels.
Solution: TYPE 241-LED for the continuous miner trailing cable. The energised CM cable glows red continuously, visible from 30+ metres in total darkness. Shuttle-car operators approaching intersections can see the CM cable path before they reach it. Personnel on foot can trace the cable without a torch. During LOTO for CM maintenance, the cable extinguishing provides instant visual confirmation of isolation. The FC-TPU™ C-Series sheath survives shuttle-car run-overs, and the FC-CVD™/FC-EMH™ C-variant maintains flicker-free illumination through the CM’s cutting/tramming/idle cycle.
Challenge: Longwall shearer power feeders run from the gate end to the shearer along the longwall face — often 300+ metres in a fully operational longwall. The shearer draws highly cyclical loads as its cutting drums engage and disengage the coal seam, and the power feeder is subjected to the full mechanical punishment of the longwall face environment — falling coal, powered-support movements, and conveyor-chain abrasion. During longwall moves and face maintenance, electricians need to identify and isolate the shearer feeder in a congested gate-end area where multiple feeders run in parallel.
Solution: TYPE 241-LED for the longwall shearer power feeder. The illuminated cable is visible along the entire face length and through the gate road, allowing personnel to trace the shearer feeder route without portable lighting. During isolation, the shearer feeder goes dark while AFC and BSL feeders remain illuminated — providing immediate visual confirmation that the correct cable has been isolated. The FC-EMH™ C-variant’s wide input-voltage tracking accommodates the full shearer duty cycle without brightness variation.
Challenge: Armoured face conveyor (AFC) and boot-end switching location (BSL) feeder cables run through the gate-end area of a longwall panel — one of the most congested cable environments in underground coal mining. Multiple high-voltage feeders, earth cables, and control cables occupy the same confined space. During longwall moves, all of these cables need to be identified, disconnected, relocated, and reconnected. Identifying the correct feeder in a congested cable run — in the dark, under time pressure — is a persistent safety challenge.
Solution: TYPE 241-LED for all AFC and BSL feeder cables. Every energised feeder glows red. During panel changeover, cables that have been isolated go dark while energised cables remain visible — creating an immediate visual map of which circuits are still live. Longwall move crews can work more quickly and more safely because they can see exactly what they’re dealing with before they touch a single cable.
Challenge: Mobile substations receive 11 kV or 22 kV incoming supply via flexible feeder cables that run from permanent switchgear in the main headings to the mobile substation position in the gate road. These HV cables are critical infrastructure — approach and isolation procedures are strictly controlled. In some mines, the 22 kV incoming feeder runs for several hundred metres through the mine. Positive identification of the HV cable — and positive confirmation that it has been isolated — is safety-critical, particularly for the mobile substation approach procedure before maintenance.
Solution: TYPE 241-LED for the mobile substation 11–22 kV incoming supply. The HV cable glows red when energised, providing an unmissable visual warning to anyone approaching the mobile substation or working near the HV cable route. During isolation, the LED extinguishing provides mine-wide visual confirmation that the HV supply has been disconnected. This is the highest-voltage LED illuminated cable in the FeiChun range — 22 kV — and the FC-EMH™ C-variant delivers effortless LED illumination at these high voltage/high field-strength conditions.
| Application | Typical Voltage | Typical Size | LED Benefit |
|---|---|---|---|
| Continuous Miner (CM) | 1.1–3.3 kV | 35–95 mm² | Trailing cable visible in production panel; reduces run-over incidents during CM tramming. |
| Longwall Shearer | 3.3–11 kV | 50–150 mm² | Feeder route visible along longwall face and gate road; aids isolation identification. |
| Longwall AFC / BSL | 3.3–6.6 kV | 70–120 mm² | Identifies energised AFC/BSL feeder cables in congested gate-end areas. |
| Panel Pump Feeder | 1.1 kV | 16–35 mm² | Traces pump feeder routes through flooded or dusty roadways. |
| Mobile Substation | 11–22 kV | 50–95 mm² | HV feeder visibility critical for safe approach and isolation of mobile substations. |
📊 TYPE 241-LED vs TYPE 260-LED vs TYPE 275-LED: Picking the Right Underground Coal LED Cable
FeiChun’s AS/NZS 1802 illuminated cable range now covers three cable types — the TYPE 241-LED (flagship flexible feeder), the TYPE 260-LED (armoured feeder), and the TYPE 275-LED (shuttle-car reeling cable). Each serves a distinct role in the underground coal mine’s electrical system. Here’s how to pick the right one — and if you’re speccing a full-mine LED rollout, you’ll likely need all three.
| Feature | TYPE 241-LED (Flagship) | TYPE 260-LED (Armoured) | TYPE 275-LED (Reeling) |
|---|---|---|---|
| Primary Role | General-purpose flexible feeder / trailing cable | Armoured fixed feeder | Shuttle-car / pump reeling cable |
| Voltage Range | 1.1–22 kV (widest) | 1.1–11 kV | 1.1 kV only |
| Part Numbers | 45 | 33 | 4 |
| Screen Type | SC elastomer (magnetically transparent — 15–20% higher EMH efficiency) | Cu/polyester braid | SC elastomer cradle |
| Armour | No armour (flexible construction) | Pliable galvanised steel wire | No armour |
| LED Architecture | Standard under-sheath | FC-ALC™ over-armour | Standard under-sheath |
| Sheath | FC-TPU™ C-Series (crushing-resistant) | FC-TPU™ A-Series (armour grade) | FC-TPU™ S-Series (50,000+ flex cycles) |
| Key Applications | CM, longwall shearer, AFC/BSL, pumps, mobile substations | Gate road feeders, main headings, panel entries | Shuttle cars, pumps, auxiliary equipment |

Shuttle-car or pump reeling cable? → TYPE 275-LED. S-Series sheath rated 50,000+ flex cycles. FC-CVD™ S-variant for flicker-free shuttle-car load tracking.
Full-mine LED rollout? → All three. TYPE 241-LED for CM, longwall, AFC, pumps, and mobile substations. TYPE 260-LED for all armoured gate-road and main-heading feeders. TYPE 275-LED for shuttle cars and pumps. Same red LED visibility, same FeiChun technology platform, same plug-and-play deployment. Your entire mine glows when it’s energised.
❓ Frequently Asked Questions: CM/Longwall Compatibility, Multi-Voltage, & Procurement
Q1: What makes the TYPE 241-LED the flagship rather than the TYPE 260-LED or TYPE 275-LED?
Three things. First, voltage range: the TYPE 241-LED covers 1.1–22 kV — no other AS/NZS 1802 LED cable goes to 22 kV. Second, application breadth: 45 part numbers covering CMs, longwall shearers, AFC drives, panel pumps, and mobile substations. Third, the magnetically transparent screen giving 15–20% higher FC-EMH™ efficiency. It’s the single most versatile illuminated cable you can spec for an underground coal operation.
Q2: Can I use the TYPE 241-LED as a straight replacement for our existing standard Type 241 cables?
Too easy. The TYPE 241-LED is a direct drop-in for standard Type 241 cables at any voltage class and conductor size. No external DC supplies, no gate end box mods, no coupler changes. Disconnect the old cable, connect the 241-LED, energise, and she glows. Weight increase is 10–14%, and the O.D. is slightly larger to accommodate the LED strip and aramid braid — but it fits existing cable handling gear, reels, and couplers without modification.
Q3: How does the TYPE 241-LED handle the extreme load cycling of a continuous miner?
Continuous miners cycle between cutting (high load, 200–400 A), tramming (medium), and idle (low). The FC-EMH™ C-variant and FC-CVD™ C-variant include enhanced energy-storage capacitor banks specifically sized to bridge these low-load intervals. The LED illumination remains completely flicker-free through the entire production cycle — cutting, tramming, idle, and back to cutting — regardless of how rapidly the CM cycles between load states. The magnetically transparent screen ensures sufficient energy harvesting even during extended idle periods.
Q4: What happens when a shuttle car runs over a TYPE 241-LED cable?
It keeps working. The FC-TPU™ C-Series sheath is specifically formulated with enhanced compressive modulus to distribute point loads across the LED strip. The aramid braid (FC-ASB™) provides additional mechanical isolation for the LED circuits. After a run-over, the cable continues to glow — the LED system is designed to survive the repeated crushing events that are a normal part of life in a development panel. Obviously, you should still try to avoid running over cables wherever possible — but when it happens (and it will), the TYPE 241-LED is built to cope.
Q5: Is the TYPE 241-LED suitable for longwall shearer cables at 6.6 kV and 11 kV?
Absolutely. Longwall shearers draw highly cyclical loads as the cutting drums engage and disengage the coal seam. The FC-EMH™ C-variant’s wide input-voltage tracking range accommodates the full shearer duty cycle without LED brightness variation. At 6.6 kV and 11 kV, the stronger magnetic field provides ample harvesting margin — combined with the magnetically transparent screen, the TYPE 241-LED delivers effortless LED illumination on longwall shearer power feeders.
Q6: What’s the minimum order and how do I get a quote?
