It integrates a continuous warning-red LED strip along the entire cable length, powered exclusively by the FC-EMH\u2122 electromagnetic induction harvesting module \u2014 which draws energy from the cable's own MV field at \u22653.6 kV. No external DC power supply is required. No modification to existing switchgear or crane electrical systems. It is a direct drop-in replacement for any standard PROTOLON (FL) flat reeling cable.\"}},{\"@type\":\"Question\",\"name\":\"Does the PROTOLON (FL) LED require an external inverter or DC power supply?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"No. The FC-EMH\u2122 induction harvesting module is fully self-powered from the electromagnetic field of the medium voltage phase conductors. From 3.6 kV upward, the FC-EMH\u2122 coil captures sufficient energy to drive the LED strip continuously. There is no external AC inverter, no dedicated DC wiring, and no changes to the crane's electrical panel or switchgear. Installation is: disconnect the existing flat reeling cable, connect the PROTOLON (FL) LED, energise the circuit, and the cable illuminates.\"}},{\"@type\":\"Question\",\"name\":\"What voltage classes does the PROTOLON (FL) NTSFLCGEWOEU-LED cover?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Two voltage series are available: 6\/10 kV series (rated 3.6\/6 kV and 6\/10 kV) with test voltages of 12 kV and 20 kV respectively, and the 8.7\/15 kV series (rated 8.7\/15 kV) tested at 24 kV. The 6\/10 kV series covers 7 constructions from 3\u00d735 mm\u00b2 to 3\u00d7185 mm\u00b2. The 8.7\/15 kV series covers 6 constructions from 3\u00d735 mm\u00b2 to 3\u00d7150 mm\u00b2.\"}},{\"@type\":\"Question\",\"name\":\"What are the primary applications for the PROTOLON (FL) LED?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Primary applications are container port cranes \u2014 specifically ship-to-shore (STS), rubber-tyred gantry (RTG), and rail-mounted gantry (RMG) cranes \u2014 where the flat reeling cable must be highly visible to operators and ground workers during night shifts, fog, rain, and dust. Secondary applications include large mobile mining equipment such as surface miners, bucket wheel excavators, and high-voltage draglines with flat-format cable drum systems, as well as fast-reeling industrial machinery requiring DIN VDE 0250-813 flat reeling compliance.\"}},{\"@type\":\"Question\",\"name\":\"What travel speed does the PROTOLON (FL) LED support on container crane reel systems?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"The PROTOLON (FL) NTSFLCGEWOEU-LED is rated for travel speeds up to 120 m\/min on gantry reeling systems \u2014 fully compatible with high-speed STS, RTG, and RMG crane cable drum operation. The flat cable construction complies with DIN VDE 0250-813 for reversed bending, roller bending, and S-type directional changes.\"}},{\"@type\":\"Question\",\"name\":\"How cold-resistant is the PROTOLON (FL) LED?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"The FC-TPU\u2122 R-Series translucent outer sheath maintains full cold flexibility to \u221240 \u00b0C \u2014 suitable for Arctic port terminals, high-altitude mining operations in Central Asia, and Siberian industrial facilities. The FC-SPM\u2122 surge protection module and FC-EMH\u2122 induction module are also cold-rated to \u221240 \u00b0C. Fixed installation rating extends to \u221250 \u00b0C ambient.\"}},{\"@type\":\"Question\",\"name\":\"How does the PROTOLON (FL) LED support LOTO (Lockout\/Tagout) procedures?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"The LED illumination is powered exclusively by the cable's own MV field. When the circuit is energised, the cable glows red along its entire length \u2014 confirming live status instantly visible from crane cab height or from the ground. When the circuit is isolated or de-energised, the LED goes dark. This gives maintenance teams an unambiguous visual indication of cable energisation status, which is critical for lockout\/tagout procedures on large container terminals and open-cut mines where the cable run may exceed hundreds of metres.\"}},{\"@type\":\"Question\",\"name\":\"What is the FC-TPU\u2122 R-Series sheath and why is translucency important?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"FC-TPU\u2122 R-Series is FeiChun's proprietary flame-retardant thermoplastic polyurethane formulated specifically for flat reeling cable applications. It maintains optical translucency so the internal warning-red LED strip remains visible through the sheath after 50,000+ reeling cycles. UV stabilisers prevent yellowing over years of outdoor crane operation. Abrasion resistance is 3\u20135\u00d7 higher than standard PCP or PUR sheaths, handling the continuous roller guide wear inherent in crane cable drum systems. The material is oil, ozone, UV, and seawater spray resistant.\"}},{\"@type\":\"Question\",\"name\":\"Can the PROTOLON (FL) LED be used on both 6\/10 kV and 8.7\/15 kV crane systems?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Yes. FeiChun manufactures two series: the 6\/10 kV series (part numbers FC-FLRL10-xxx) and the 8.7\/15 kV series (part numbers FC-FLRL15-xxx). Both share the same FC-EMH\u2122 induction harvesting technology, FC-LED\u2122 warning red strip, FC-TPU\u2122 R-Series sheath, and FC-SPM\u2122 surge protection. The 8.7\/15 kV series has increased insulation wall thickness per VDE 0250-813 requirements for that voltage class.\"}}]}\n<\/script>\n<script type=\"application\/ld+json\">\n{\"@context\":\"https:\/\/schema.org\",\"@type\":\"Product\",\"name\":\"PROTOLON (FL) NTSFLCGEWOEU-LED MV Flat Reeling Cable \u2014 FeiChun VDE 0250-813 | 3.6\/6 kV \u2013 8.7\/15 kV | Self-Powered LED | No External DC | Container Crane &amp; Mining\",\"brand\":{\"@type\":\"Brand\",\"name\":\"FeiChun\"},\"manufacturer\":{\"@type\":\"Organization\",\"name\":\"FeiChun Special Cables\",\"url\":\"https:\/\/feichuncables.com\"},\"description\":\"World's first LED-illuminated MV flat reeling cable.

At those voltages, inadvertent contact \u2014 by a ground operator, a reach stacker tyre, a dock vehicle \u2014 produces instantly fatal results. Yet in the environments where these cables operate, visibility is almost always compromised: container terminal night shifts, fog and rain over the apron, dust storms at open-pit operations, the glare of crane floodlights that paradoxically obscure the cable directly below them. The cable lies where it must lie \u2014 across the travel path of other equipment \u2014 and it cannot always be barricaded or physically protected.<\/p>\n    <p>The existing answer \u2014 <strong>electroluminescent (EL) wire systems<\/strong> such as TENAX-LUMEN and equivalent products \u2014 addressed the visibility requirement but introduced a new failure point: the external AC\/AC inverter required to drive the EL phosphor wire. Every inverter is a box mounted at the cable termination, requiring its own cabling, periodic maintenance, and replacement when the phosphor fades after 10,000\u201315,000 hours. More critically, EL systems cannot indicate energisation status: the cable glows whether the MV conductors are live or isolated, because the illumination comes from an independent power source. For lockout\/tagout (LOTO) purposes \u2014 which require a worker to verify that the cable is de-energised before approaching \u2014 a cable that always glows provides <strong>no useful information<\/strong>.<\/p>\n    <p>FeiChun&#8217;s <strong>PROTOLON (FL) NTSFLCGEWOEU-LED<\/strong> solves both problems. It illuminates from the cable&#8217;s own medium voltage field \u2014 no external inverter, no external wiring \u2014 and it goes dark when the MV conductors are de-energised, giving maintenance teams a true visual energisation indicator along the entire cable length. This is not an incremental improvement to existing technology. It is a fundamentally different architecture, and it is <strong>the world&#8217;s first LED-illuminated MV flat reeling cable<\/strong> certified to DIN VDE 0250-813.<\/p>\n\n    <div class=\"note amber\">\n      <div class=\"nt\">\u2b50 World First \u2014 VDE 0250-813 LED Flat Reeling Cable<\/div>\n      <p>No other manufacturer currently offers an LED-illuminated medium voltage flat reeling cable that is self-powered from the MV field and certified to DIN VDE 0250-813. The PROTOLON (FL) NTSFLCGEWOEU-LED is FeiChun&#8217;s exclusive product, protected under the FC-EMH\u2122 and FC-TPU\u2122 proprietary technology portfolio. FC-EMH\u2122 induction harvesting operates across all three voltage classes (3.6\/6 kV, 6\/10 kV, 8.7\/15 kV) and across all flat cable constructions from 3\u00d735 to 3\u00d7185 mm\u00b2.<\/p>\n    <\/div>\n\n    <!-- SECTION 2 -->\n    <h2 id=\"s2\">\ud83d\udd0d What Is the PROTOLON (FL) NTSFLCGEWOEU-LED? Construction &amp; Designation<\/h2>\n    <p>The designation <strong>NTSFLCGEWOEU-LED<\/strong> follows the standard German cable designation system applied to flexible MV reeling cables under DIN VDE 0250-813, with the <strong>-LED<\/strong> suffix denoting FeiChun&#8217;s integrated LED illumination upgrade. The base cable designation identifies the key construction elements: N (VDE standard construction), T (flexible\/reeling), S (screened), FL (flat), C (copper conductors), G (EPR rubber insulation), E (earthing conductors), WO (special outer sheath), EU (European market) \u2014 with the LED suffix marking the full FC-EMH\u2122 + FC-LED\u2122 integration.<\/p>\n    <p>In practical terms, the PROTOLON (FL) LED is a <strong>medium voltage flat reeling cable<\/strong> designed for applications where the cable must pay out and wind onto a drum in a flat orientation \u2014 specifically container cranes (STS, RTG, RMG), ship-to-shore gantry systems, large mobile mining and earthmoving equipment, and industrial fast-reel systems. The flat format \u2014 rather than the round trailing cable format of the (N)TSCGH3S series \u2014 is determined by the cable drum design and the reel guide roller system of the specific crane or machine. Flat reeling cables must undergo reversed bending, roller bending, and S-type directional changes within a single plane, and VDE 0250-813 specifies the mechanical performance requirements for all of these.<\/p>\n\n    <div class=\"note blue\">\n      <div class=\"nt\">\ud83d\udcd0 Flat vs Round Reeling \u2014 When to Specify PROTOLON (FL)<\/div>\n      <p>Specify PROTOLON (FL) NTSFLCGEWOEU-LED when the crane or machine uses a <strong>flat drum reel system<\/strong> with a guide roller assembly designed for flat cable geometry. Most large container cranes \u2014 STS, RTG (particularly those with horizontal reel systems), and RMG cranes \u2014 use flat reeling cable. Electric rope shovels and walking draglines typically use <strong>round trailing cables<\/strong> (such as the (N)TSCGH3S-LED series). If uncertain, consult FeiChun with the cable drum drawing and guide roller specification.<\/p>\n    <\/div>\n\n    <!-- SECTION 3 -->\n    <h2 id=\"s3\">\u26a1 FC-EMH\u2122 Induction Harvesting: How Self-Powered LED Works at MV<\/h2>\n    <p>The FC-EMH\u2122 (FeiChun Electromagnetic Harvesting) module is the core of the PROTOLON (FL) LED system. It is a purpose-engineered induction pickup coil wound on an <strong>aramid fibre centre<\/strong>, integrated within the cable&#8217;s inner sheath layer. The coil geometry is specifically optimised for the <strong>flat parallel core arrangement<\/strong> of the FL cable format \u2014 ensuring uniform field coupling across all three phase conductors and maximising harvesting efficiency at the flat cable&#8217;s characteristic inter-conductor spacing.<\/p>\n    <p>The operating principle is straightforward: when the MV phase conductors carry current at \u22653.6 kV, they generate a surrounding electromagnetic field proportional to the current magnitude. The FC-EMH\u2122 coil, in close proximity to the conductors within the cable structure, develops an induced EMF in this field. This induced voltage is rectified, filtered, and regulated by the FC-SPM\u2122 surge protection module to produce the stable 12\/24 V DC supply that drives the FC-LED\u2122 warning red strip. <strong>No electrical connection is made between the LED circuit and the MV conductors<\/strong> \u2014 full galvanic isolation is maintained throughout, complying with VDE isolation requirements.<\/p>\n    <p>When the MV circuit is de-energised \u2014 isolator open, circuit breaker tripped, maintenance isolation applied \u2014 the electromagnetic field collapses, the FC-EMH\u2122 coil ceases to harvest, and the LED strip extinguishes. The cable <strong>goes dark within seconds of de-energisation<\/strong>. When the circuit is re-energised, the LED illuminates within seconds of current flow. This makes the cable a true real-time energisation indicator \u2014 not a static luminescent element powered from an independent source.<\/p>\n\n    <div class=\"note green\">\n      <div class=\"nt\">\u2705 FC-EMH\u2122 HV Flat Variant \u2014 Technical Summary<\/div>\n      <p><strong>Harvesting threshold:<\/strong> \u22653.6 kV (all three voltage classes). <strong>Coil type:<\/strong> Aramid-centre wound induction pickup, flat geometry optimised. <strong>Galvanic isolation:<\/strong> Complete \u2014 no connection between LED circuit and MV conductors. <strong>Output:<\/strong> Regulated 12\/24 V DC via FC-SPM\u2122 Layer 3. <strong>Cold rating:<\/strong> \u221240 \u00b0C (flexible), \u221250 \u00b0C (fixed). <strong>Maintenance:<\/strong> Zero.

During a maintenance isolation, the crew in the crane cab opens the circuit breaker. A ground worker 200 metres away must confirm the cable is de-energised before approaching. With an EL-string system, the cable continues to glow \u2014 driven by the external inverter \u2014 regardless of whether the MV conductors are live or dead. The ground worker has no visual confirmation of isolation. With the PROTOLON (FL) LED, the cable goes dark within seconds of circuit isolation. The cable&#8217;s own behaviour confirms the isolation. At 3.6\u201315 kV, this distinction is not a comfort feature. It is a fatality-prevention mechanism.<\/p>\n    <\/div>\n\n    <!-- SECTION 5 -->\n    <h2 id=\"s5\">\ud83d\udd27 Cable Construction: Layer-by-Layer from Conductor to Outer Sheath<\/h2>\n    <p>The PROTOLON (FL) NTSFLCGEWOEU-LED is built on FeiChun&#8217;s established flat reeling cable platform, with the LED system integrated as a structural element of the cable \u2014 not as an add-on surface feature. The construction sequence from centre to outside is as follows.<\/p>\n\n    <h3>Conductors \u2014 Tinned Copper, Class 5<\/h3>\n    <p>Phase conductors are finely stranded copper, tinned, manufactured to IEC 60228 \/ DIN EN 60228 Class 5. Tinning provides resistance to oxidation in the humid environments of port installations and reduces contact resistance at terminations after long field service. Earth (PE) conductors use individual concentric Class 5 stranding with SC special rubber \u2014 split into pairs distributed symmetrically in the inter-conductor interstices of the flat arrangement.<\/p>\n\n    <h3>Insulation \u2014 EPR Rubber Compound 3GI3<\/h3>\n    <p>Each phase conductor is insulated with EPR (ethylene propylene rubber) compound 3GI3, with inner and outer semi-conductive layers providing field grading across the insulation wall. The outer semi-conductive screen uses SC NBR (nitrile-butadiene rubber) with an easy-strip formulation for reliable termination without conductor damage. The insulation wall thickness is specified per DIN VDE 0250-813 for each voltage class \u2014 the 8.7\/15 kV series carries a heavier wall than the 6\/10 kV series.<\/p>\n\n    <h3>Core Arrangement \u2014 Flat Parallel with Polyester Mesh Reinforcement<\/h3>\n    <p>The three insulated phase conductors are arranged in a parallel flat configuration \u2014 not twisted or cabled as in a round construction. Earth conductors are distributed in the interstices between and beside the phase cores. A <strong>polyester mesh tape<\/strong> reinforcement layer provides dimensional stability under the tensile and bending loads inherent in flat reeling cable operation, maintaining the flat geometry during repeated drum winding and deployment.<\/p>\n\n    <h3>Inner Sheath &amp; FC-EMH\u2122 Module<\/h3>\n    <p>The inner sheath is EPR rubber compound 5GM5 \u2014 a high-flexibility formulation suited for dynamic reeling applications. Within or immediately under the inner sheath layer, the <strong>FC-EMH\u2122 electromagnetic induction module<\/strong> is integrated: a precision-wound induction pickup coil on an aramid fibre centre. The aramid core provides additional tensile strength and dimensional stability to the module under the mechanical stresses of flat reeling operation.<\/p>\n\n    <h3>LED Strip \u2014 Warning Red 620\u2013630 nm, Silicone Encapsulated<\/h3>\n    <p>The FC-LED\u2122 warning red strip (wavelength 620\u2013630 nm, ANSI\/ISO warning red) is silicone-encapsulated for protection against mechanical stress and moisture ingress. The strip runs continuously along the cable length, positioned between the inner sheath and the FC-ASB\u2122 aramid stress braid. Silicone encapsulation maintains LED performance across the \u221240 \u00b0C to +80 \u00b0C operating range without brittleness or delamination.<\/p>\n\n    <h3>FC-ASB\u2122 Aramid Stress Braid<\/h3>\n    <p>The FC-ASB\u2122 (FeiChun Aramid Stress Braid) is an aramid fibre braid layer that absorbs the dynamic tensile loads transferred to the cable during high-speed reeling operation, protecting the LED strip and inner cable structure from tensile stress concentration. Aramid fibre is selected for its high tensile strength-to-weight ratio and dimensional stability under cyclic loading.<\/p>\n\n    <h3>Outer Sheath \u2014 Translucent FR-TPU (FC-TPU\u2122 R-Series)<\/h3>\n    <p>The outer sheath uses FeiChun&#8217;s proprietary FC-TPU\u2122 R-Series (Formula FC-2026-TPU-R9) \u2014 a flame-retardant thermoplastic polyurethane formulated exclusively for flat reeling cable applications. It is optically translucent to allow the warning red LED to be clearly visible from outside the cable in all operating conditions. Full details in Section 7 below.<\/p>\n\n    <!-- SECTION 6 -->\n    <h2 id=\"s6\">\ud83d\udee1\ufe0f FC-SPM\u2122 Four-Layer Surge Protection for Crane Motor &amp; VFD Environments<\/h2>\n    <p>Container crane and mining equipment drive systems are severe environments for cable-integrated electronics. Variable frequency drives (VFDs) used on crane hoist and travel motors generate fast-rising voltage transients on the power conductors. Crane motor starting inrush \u2014 particularly the high-current inrush of STS hoist motors during emergency stops and restarts \u2014 produces abrupt electromagnetic field changes in the FC-EMH\u2122 harvesting zone.

The PROTOLON (FL) NTSFLCGEWOEU-LED is a genuine market first, developed and manufactured exclusively by FeiChun. FC-EMH\u2122 induction harvesting operates from 3.6 kV to 15 kV across all flat cable constructions.<\/p>\n\n    <h3>2 \u2014 Zero External Power Supply<\/h3>\n    <p>No external DC supply. No AC\/AC inverter. No additional wiring runs. No modifications to the crane&#8217;s electrical panel, switchgear, or cable termination arrangement. The PROTOLON (FL) LED draws everything it needs from the cable&#8217;s own electromagnetic field. The entire installation procedure is: disconnect the existing flat reeling cable, connect the PROTOLON (FL) LED, energise, glow.<\/p>\n\n    <h3>3 \u2014 True Live\/Dead Visual Indication for LOTO Safety<\/h3>\n    <p>The cable illuminates only when the MV conductors are energised. When isolated, it goes dark. This is a critical safety distinction for lockout\/tagout procedures on large port and mine sites where MV cable runs may extend hundreds of metres and visual confirmation of de-energisation cannot be achieved at the switchgear panel itself. The LED strip provides that confirmation at the cable, along the entire cable length.<\/p>\n\n    <h3>4 \u2014 Full DIN VDE 0250-813 Flat Reeling Compliance<\/h3>\n    <p>Certified for reversed bending, roller bending, and high-speed reeling at up to 120 m\/min \u2014 covering the full operational demand of STS, RTG, and RMG crane cable drum systems. The integrated LED system does not compromise any of the mechanical performance requirements specified in VDE 0250-813 for flat reeling cable applications.<\/p>\n\n    <h3>5 \u2014 50,000+ Cycle Sheath Life \u2014 Heavy Crane Durability<\/h3>\n    <p>The FC-TPU\u2122 R-Series outer sheath is engineered for 50,000+ reeling cycles at 3\u20135\u00d7 the abrasion resistance of standard PCP or PUR sheaths. Anti-yellowing UV stabilisers maintain LED optical clarity throughout the cable&#8217;s operational life in outdoor crane and port environments.<\/p>\n\n    <h3>6 \u2014 Maintenance-Free FC-SPM\u2122 Surge Protection<\/h3>\n    <p>Four-layer cold-rated surge protection with PTC auto-reset. No maintenance required over the cable&#8217;s service life. Designed specifically for crane VFD transients and high-current motor inrush in STS and mining equipment drive systems.<\/p>\n\n    <h3>7 \u2014 Night Shift, Fog &amp; Dust Storm Visibility<\/h3>\n    <p>Continuous warning red (620\u2013630 nm) illumination along the entire cable run \u2014 visible to crane operators, ground staff, and vehicle drivers during night operations, fog, heavy rain, and dust storms on container terminals and open-cut mine sites. The LED wavelength is selected for maximum human visual detection in low-visibility industrial environments.<\/p>\n\n    <h3>8 \u2014 Vietnam Port &amp; Industrial Market Applications<\/h3>\n    <p>Certified for container crane upgrade projects at Hai Phong, Ho Chi Minh City, Da Nang, and Vung Tau ports. Compatible with STS, RTG, and RMG crane systems from all major manufacturers. TCVN local compliance documentation available on request for Vietnamese port authority procurement processes.<\/p>\n\n    <!-- SECTION 13 -->\n    <h2 id=\"s13\">\ud83c\udfd7\ufe0f Application Guide: STS, RTG, RMG Cranes &amp; Mobile Mining Equipment<\/h2>\n\n    <h3>Ship-to-Shore (STS) Container Cranes<\/h3>\n    <p>STS cranes are the primary application for the PROTOLON (FL) LED in the 6\/10 kV and 8.7\/15 kV series. Large STS cranes \u2014 with outreach exceeding 60 metres and lift capacity above 65 tonnes \u2014 typically operate at 6\/10 kV or higher. The flat reeling cable drum is located at the crane base or trolley level, with the cable paying out as the crane trolley travels across the boom. Night operations and foggy conditions in port environments make the continuous red LED glow a critical safety feature for apron workers and reach stacker operators working below and around the crane structure.<\/p>\n\n    <h3>Rubber-Tyred Gantry (RTG) Cranes<\/h3>\n    <p>RTG cranes use flat reeling cable drums as part of the shore power connection system, where the cable must pay out and wind in as the crane moves along the container yard. At 3.6\/6 kV or 6\/10 kV, the PROTOLON (FL) LED in the 3\u00d735 to 3\u00d7120 mm\u00b2 range covers the full power supply requirement of contemporary RTG crane shore power systems. LED visibility is particularly valuable at RTG operations where the cable lies on or near the travel path of straddle carriers and container transporters.<\/p>\n\n    <h3>Rail-Mounted Gantry (RMG) Cranes<\/h3>\n    <p>RMG cranes at automated container terminals may operate 24 hours with minimal personnel on the terminal apron \u2014 but maintenance access during isolated windows requires visual cable energisation confirmation. The PROTOLON (FL) LED&#8217;s live\/dead indication provides that confirmation without requiring the maintenance team to carry and deploy additional voltage detection equipment at the cable location.<\/p>\n\n    <h3>Large Mobile Mining Equipment<\/h3>\n    <p>Surface miners, bucket wheel excavators, and high-capacity mobile crushing and screening equipment that use flat reeling cable drum systems at 6\/10 kV to 8.7\/15 kV benefit from the same visibility and LOTO advantages as port crane applications. The \u221240 \u00b0C cold flex rating and oil\/chemical resistance of the FC-TPU\u2122 R-Series sheath address the specific environmental requirements of open-cut mining operations in Central Asia, Russia, and high-altitude South American mining regions.<\/p>\n\n    <!-- SECTION 14 \u2014 FAQ -->\n    <h2 id=\"s14\">\u2753 Frequently Asked Questions<\/h2>\n\n    <h3>Does the PROTOLON (FL) LED require an external inverter or DC power supply?<\/h3>\n    <p>No. The FC-EMH\u2122 induction harvesting module is fully self-powered from the electromagnetic field of the medium voltage phase conductors. From 3.6 kV upward, the FC-EMH\u2122 coil captures sufficient energy to drive the LED strip continuously. There is no external AC inverter, no dedicated DC wiring, and no changes to the crane&#8217;s electrical panel or switchgear. Installation is: disconnect the existing flat reeling cable, connect the PROTOLON (FL) LED, energise the circuit, and the cable illuminates.<\/p>\n\n    <h3>What voltage classes does the PROTOLON (FL) LED cover?<\/h3>\n    <p>The 6\/10 kV series (part numbers FC-FLRL10-xxx) covers 3.6\/6 kV and 6\/10 kV rated voltages, with test voltages of 12 kV and 20 kV respectively. The 8.7\/15 kV series (FC-FLRL15-xxx) is rated at 8.7\/15 kV with 24 kV test voltage. Both series share the same FC-EMH\u2122 LED technology and FC-TPU\u2122 R-Series outer sheath.<\/p>\n\n    <h3>Is the PROTOLON (FL) LED a direct drop-in replacement for standard PROTOLON (FL) reeling cables?<\/h3>\n    <p>Yes. The PROTOLON (FL) NTSFLCGEWOEU-LED is designed as a direct drop-in replacement for standard PROTOLON (FL) flat reeling cables in the same conductor cross-sections, rated voltage, and flat cable geometry. No changes to the cable drum, guide roller system, or cable terminations are required. The weight increase of 8\u201312% above the standard PROTOLON (FL) is the only parameter that may require verification against the cable drum load rating before installation.<\/p>\n\n    <h3>What is the travel speed rating?<\/h3>\n    <p>Up to 120 m\/min on gantry reeling systems. This covers the full operational speed range of contemporary STS, RTG, and RMG crane cable reel systems. The rating complies with DIN VDE 0250-813 requirements for flat reeling cable mechanical performance at the specified speed class.<\/p>\n\n    <h3>Can the PROTOLON (FL) LED be used in Arctic or cold-climate port operations?<\/h3>\n    <p>Yes. The FC-TPU\u2122 R-Series sheath maintains full flexibility to \u221240 \u00b0C, and both the FC-EMH\u2122 module and FC-SPM\u2122 surge protection are cold-rated to \u221240 \u00b0C. Fixed installation rating extends to \u221250 \u00b0C ambient. This covers Arctic container terminals, high-altitude mining operations, and port facilities in Northern Europe and Canada.<\/p>\n\n    <h3>How does the LED system affect the cable&#8217;s DIN VDE 0250-813 certification?<\/h3>\n    <p>The PROTOLON (FL) NTSFLCGEWOEU-LED is certified to DIN VDE 0250-813 as a complete cable system \u2014 the LED integration is part of the certified construction, not an aftermarket modification. The FC-EMH\u2122 module, FC-LED\u2122 strip, FC-ASB\u2122 aramid braid, and FC-TPU\u2122 R-Series sheath are all elements of the certified cable design. The LED system does not affect the cable&#8217;s mechanical performance parameters (bending radius, tensile rating, travel speed) or its electrical performance parameters (conductor resistance, capacitance, current capacity).<\/p>\n\n    <h3>Is the outer sheath halogen-free?<\/h3>\n    <p>A halogen-free formulation of the FC-TPU\u2122 R-Series outer sheath is available on request for applications requiring IEC 60754-2 compliance. The standard FC-TPU\u2122 R-Series sheath is flame retardant per IEC 60332-1-2 (self-extinguishing). Contact <a href=\"mailto:Tech@feichuncables.com\">Tech@feichuncables.com<\/a> to specify halogen-free requirements at the time of order.<\/p>\n\n    <h3>Is fibre-optic integration available in the PROTOLON (FL) LED?<\/h3>\n    <p>Yes. Custom fibre-optic integration is available on request for both the 6\/10 kV and 8.7\/15 kV series. Fibre options include 6, 12, 18, or 24 fibres in G62.5 multimode, G50 multimode, or E9 singlemode configurations.
