1. What This Cable Family Is — and What It Is Not
АсВВГ, АсВВГнг(А), АсВВГнг(А)-LS, АсВВГнг(А)-LSLTx, АсВВГ-П, АсППГнг(А)-HF and their flat/fire-performance variants are 0.66/1 kV power cables for stationary installations. The public product description for TU 16.К73.170-2018 identifies aluminum-alloy conductors and explicitly states that the cables are intended for transmission and distribution of electrical energy in stationary installations at 0.66 and 1 kV, 50 Hz. [1] This positioning is consistent with the general IEC concept for 1 kV extruded-insulation power cables used in fixed distribution and industrial installations. [2]
Critical application boundary: do not specify АсВВГ as a continuous-motion reel, festoon or drag-chain cable
Class 1 and Class 2 conductor constructions are fixed-installation conductor classes. IEC 60228 distinguishes Class 1 solid and Class 2 stranded conductors for fixed installations from Class 5 and Class 6 flexible copper conductors. [3] The supplied АсВВГ data also defines installation bending radii, not continuous flex-cycle ratings. Therefore, a crane reel, moving festoon, cable-protection chain, longwall miner, mobile drill or travelling ship-unloader requires a dedicated dynamic-cable design rather than simply a “more flexible” АсВВГ construction.
This distinction matters commercially and technically. Port and mining engineers often search a voltage and a cable name first, then discover later that the dominant failure mechanism is mechanical rather than electrical: conductor work-hardening, sheath abrasion, tensile load, torsion or repeated bending. Feichun’s engineering approach should therefore be understood as a two-platform architecture: (1) TU 16.К73.170-2018 aluminum-alloy power cables for stationary distribution, and (2) separately designed high-flex mining, reeling, festoon and drag-chain cables for equipment in motion. Feichun’s own technical library describes reel systems as a combined tensile, bending, torsional, UV, salt-spray and abrasion problem rather than a conventional fixed-cable problem. [4]
1.1 Nomenclature: how engineers should read the suffixes
| Marking | Engineering meaning | Material / fire strategy | Typical decision driver |
|---|---|---|---|
| АсВВГ | Aluminum-alloy conductor; PVC insulation; PVC sheath | Baseline PVC | Fixed routes where single-cable flame limitation is acceptable |
| АсВВГнг(А) | As above, with reduced-flammability compound | Grouped flame propagation Category A | Cable galleries, grouped industrial routes |
| …-LS | Low smoke / reduced fire hazard | Reduced smoke and gas evolution | Enclosed spaces where visibility and smoke burden matter |
| …-LSLTx | Low smoke + low toxicity | Reduced toxicity of combustion products | Hospitals, schools, care facilities, sleeping accommodation |
| АсППГнг(А)-HF | Halogen-free polymer insulation/sheath family | Low corrosivity / halogen-free strategy | Occupied or equipment-dense interiors where corrosive gases are a major hazard |
| “-П” | Flat construction | Same fire suffix logic, altered geometry | Low-profile fixed routing and planar installation constraints |

2. Cable Construction: Layer-by-Layer Engineering Logic
The TU 16.К73.170-2018 family combines an aluminum-alloy current-carrying conductor with thermoplastic or halogen-free polymer insulation systems chosen according to the fire-performance suffix. The conductor may be solid or stranded, round, Class 1 or Class 2 to GOST 22483. GOST 22483:2021, aligned with IEC 60228:2004, classifies conductors into classes and identifies Classes 1 and 2 as fixed-installation constructions. [6]
2.1 Why aluminum alloy is an engineering decision, not just a raw-material substitution
For large cross-sections, aluminum-based conductors reduce cable mass and can lower structural loading on long cable trays, galleries and vertical risers. The engineering trade-off is that termination design becomes more important: connector metallurgy, contact pressure, oxide management, creep behaviour and the connector’s approved conductor range must be checked as a system. IEC 61238-1-1 explicitly covers compression and mechanical connectors for power cables up to 1 kV and includes aluminum conductors across substantial cross-section ranges. [7]
Feichun engineering emphasis: conductor / connector / route as one system
For project engineering, “same mm²” is not a sufficient substitution rule between copper, conventional aluminum and aluminum-alloy conductors. A professional substitution review should check conductor DC resistance, permissible current under the actual route, voltage drop, short-circuit duty, terminal lug compatibility, thermal expansion, installation pulling load, support spacing and fire class. The cable should be selected from the electrical and mechanical system requirements, not from conductor price alone.
2.2 Nominal voltage, number of cores and supplied cross-section ranges
| Cable family | No. of cores | 0.66 kV range | 1 kV range |
|---|---|---|---|
| АсВВГ, АсВВГнг(А), АсВВГнг(А)-LS, АсВВГнг(А)-LSLTx, АсППГнг(А)-HF | 1 | 2.5–800 mm² | 2.5–800 mm² |
| same round family | 2 | 2.5–240 mm² | 2.5–240 mm² |
| same round family | 3 | 2.5–400 mm² | 2.5–400 mm² |
| same round family | 4 | 2.5–400 mm² | 2.5–400 mm² |
| same round family | 5 | 2.5–240 mm² | 2.5–240 mm² |
| АсВВГ-П, АсВВГ-Пнг(А), АсВВГ-Пнг(А)-LS, АсВВГ-Пнг(А)-LSLTx, АсППГ-Пнг(А)-HF | 2 or 3 | 2.5–16 mm² | 2.5–16 mm² |

3. Fire-Performance Selection: Choose the Suffix by Consequence, Not Habit
GOST 31565-2012 is the central fire-safety classification framework for cable products used where fire requirements apply. The supplied specification maps the family to the following classes. Independent public certification records using the same GOST classification show the same class mapping for нг(А), LS, LSLTx and HF constructions, including П1б.8.2.2.2 for нг(А)-LS, П1б.8.2.1.2 for нг(А)-LSLTx and П1б.8.1.2.1 for нг(А)-HF. [8] [9]
| Family | Compound strategy | Fire objective | GOST 31565 class | Preferred engineering context |
|---|---|---|---|---|
| АсВВГ, АсВВГ-П | Standard PVC | Single-cable flame limitation | О1.8.2.5.4 | Single laying; grouped laying requires fire-protection measures |
| АсВВГнг(А), АсВВГ-Пнг(А) | Reduced-flammability PVC | Bunched cable, Category A | П1б.8.2.5.4 | Outdoor cable structures / industrial grouped routes, subject to combustible-load design |
| АсВВГнг(А)-LS, АсВВГ-Пнг(А)-LS | Low-fire-hazard PVC | Category A + reduced smoke/gas | П1б.8.2.2.2 | Indoor electrical installations, buildings and enclosed cable structures |
| АсВВГнг(А)-LSLTx, АсВВГ-Пнг(А)-LSLTx | Low-fire-hazard, low-toxicity PVC | Category A + low smoke + low toxicity | П1б.8.2.1.2 | Child-care/education, hospitals, care facilities and sleeping accommodation where low toxicity is prioritized |
| АсППГнг(А)-HF, АсППГ-Пнг(А)-HF | Halogen-free polymer compound | Category A + halogen-free / low corrosivity | П1б.8.1.2.1 | Internal installations and occupied buildings where corrosive combustion products are a key design concern |
Single-cable flame tests and bunched-cable flame tests answer different questions. IEC 60332-1-2 evaluates flame propagation on a single vertical insulated wire or cable, while IEC 60332-3-22 Category A evaluates a vertically mounted bunch with a defined high volume of non-metallic material. [10] [5] Therefore, passing a single-cable test should never be used to infer behaviour in a dense vertical bundle.

4. Current-Carrying Capacity, Insulation Resistance and Thermal Limits
The table below reproduces the supplied current-rating and insulation-resistance data without reducing the cross-section range. The reference condition for current ratings in air is an ambient temperature of 25 °C. For four-core cables with equal conductor sections in four-wire networks loaded in all conductors during normal operation, and for five-core cables, the supplied values require multiplication by 0.93. Where real installation conditions differ, correction factors or a project-specific thermal calculation are required. IEC 60287-1-1 provides the international calculation framework for steady-state cable current ratings and losses. [11]

* Supplied table: single-core AC installation in touching trefoil formation. ** For four-core equal-section four-wire systems loaded in all cores, and for five-core cables, multiply applicable multicore current values by 0.93. Insulation resistance values are normalized to 1 km and 20 °C.
4.1 Ambient-temperature correction factors
| Calculated ambient temperature | Current correction factor |
|---|---|
| -5 °C | 1.29 |
| 0 °C | 1.24 |
| 5 °C | 1.20 |
| 10 °C | 1.15 |
| 15 °C | 1.11 |
| 20 °C | 1.05 |
| 25 °C | 1.00 |
| 30 °C | 0.94 |
| 35 °C | 0.88 |
| 40 °C | 0.81 |
| 45 °C | 0.74 |
| 50 °C | 0.67 |
4.2 Worked thermal selection examples engineers can reuse
Example A — hot port cable gallery: A 240 mm² multicore cable has a supplied 25 °C current rating of 359 A. At a calculated ambient of 50 °C, the supplied correction factor is 0.67, giving 359 × 0.67 = 240.5 A. This shows why “nameplate ampacity” should not be copied into a tropical port or enclosed conveyor gallery design without correction.
Example B — four-core network with all cores loaded: For a 120 mm² multicore cable, the supplied value is 229 A. Applying the specified 0.93 factor gives 229 × 0.93 = 213 A before any additional ambient, grouping or installation corrections.
Example C — overload mode: The supplied instruction allows overload current values to be estimated by multiplying the table by 1.16. For 240 mm² multicore, 359 × 1.16 = 416.4 A. This must not be interpreted as a permanent rating: conductor temperature in overload is limited to 90 °C and the duration/duty must be governed by the project protection and thermal model.
4.3 Short-circuit verification
The supplied one-second short-circuit values are accompanied by the scaling rule:
For a 240 mm² conductor with a supplied 1-second short-circuit current of 17.54 kA, a 0.2-second clearing time gives 17.54 / √0.2 = 39.2 kA. The supplied conductor-temperature limits are ≤160/140 °C at short-circuit current (the lower value applying to the stated large-section condition) and 350 °C as the non-ignition limiting temperature. Protection coordination should always verify the exact cable construction, initial temperature and protective-device clearing time.

Feichun Dynamic Cable Engineering Platform
7. Where Feichun’s High-Flex, Tensile-Resistant and Abrasion-Resistant Mining Cable Technology Fits
A stationary power cable and a moving-machine cable fail by different mechanisms. In a fixed АсВВГ route, the design problem is dominated by electrical loading, thermal environment, fire class, installation bend, termination and route protection. In a reeling, trailing, festoon or drag-chain system, the design problem adds cyclic bending, torsion, tensile loading, self-weight fatigue, abrasion, roller pressure, impact and repeated acceleration. Feichun’s published port-crane engineering material specifically identifies simultaneous tensile loading, cyclical bending, torsional forces, salt spray, UV and oil exposure in reel applications. [4]
Feichun dynamic-cable design toolbox
For mobile mining and port machinery, Feichun’s engineering platform can use fine-stranded flexible copper conductors; fatigue-resistant conductor lay; elastomeric EPR/rubber insulation; chloroprene/CPE/TPU or other abrasion-resistant sheath systems selected to the environment; centrally balanced or symmetric core geometry to control torsion; textile or aramid tensile elements to off-load conductor strain; and project-specific reinforcement for reeling, trailing, festoon or cable-protection-chain service. These are purpose-built dynamic architectures and must not be assumed to be properties of the Class 1/2 aluminum-alloy АсВВГ fixed-installation family.
Feichun’s technical library describes a reinforced festoon/port-crane concept in which tensile reinforcement is used to prevent cable self-weight and cyclic motion from being transferred directly into the conductors. [12] The same engineering principle is relevant to deep mine shafts, bucket-wheel excavators, mobile ship loaders and long-travel crane systems: mechanical load paths must be designed independently from electrical current paths.
7.1 Dynamic cable design: the four-layer reliability model
- Conductor fatigue control: fine strand count, optimized bunching/lay and controlled conductor mobility reduce bending strain concentration.
- Tensile-load management: textile/aramid reinforcement or cable geometry carries self-weight and pulling load so conductor strands are not used as structural members.
- Abrasion and impact defence: heavy-duty elastomeric or TPU/CPE/CR sheath systems are selected for rollers, guideways, mining floors, cable troughs and abrasive dust.
- Torsion and neutral-axis management: symmetric core geometry, suitable fillers and controlled lay length reduce corkscrewing, core migration and local pressure during reeling or chain travel.
Scene Applications · Correct Product Mapping
8. Application Map: Fixed Route, Festoon, Reel and Drag Chain
Stationary Distribution
Cable trays, fixed mine power distribution, plant rooms, stationary conveyor feeders and fixed port infrastructure are the natural design space, subject to mechanical protection and fire-class selection.
Festoon Motion
Repeated loop bending and trolley travel require a flexible conductor and sheath system. Use a Feichun festoon-specific cable, not Class 1/2 АсВВГ.
Reel / Spool Duty
Continuous winding adds tension, bending, torsion and drum pressure. Specify a reel-rated Feichun dynamic cable with defined mechanical system parameters.
Reciprocating Chain
Repeated bending on a defined radius requires a chain-rated flexible construction with suitable conductor stranding, lay and abrasion control.
Real-world references show the same mechanical distinction visually: festoon systems support repeated hanging cable loops, while reel systems repeatedly wind and unwind cable from a drum. For engineering reference images, see industrial festoon and reel examples from established cable-management equipment suppliers. The page intentionally uses original SVG illustrations rather than hot-linking third-party photographs.
Technical Comparison · Selection Logic
9. АсВВГ Fixed Power Cable vs Dedicated Dynamic Mining / Port Cable
| Criterion | АсВВГ / нг(А) / LS / LSLTx / HF | Feichun dynamic mining / port design | Engineering consequence |
|---|---|---|---|
| Primary duty | Stationary power distribution | Moving equipment power / control | Choose by movement regime first |
| Conductor class | Class 1 / 2 aluminum alloy | Typically fine-stranded flexible copper architecture | Fatigue behaviour is fundamentally different |
| Continuous reeling | Not intended | Purpose-designed variants available | Do not substitute fixed cable into a reel system |
| Festoon travel | Not intended for repetitive trolley flexing | Flat/round festoon architectures available | Mechanical load path and neutral axis must be engineered |
| Drag chain | Not chain-rated | Chain-specific flexible constructions available | Cycle life depends on conductor, lay, radius and chain geometry |
| Fire options | нг(А), LS, LSLTx, HF family | Can be engineered to project fire/material requirements | Fire and motion requirements must be satisfied simultaneously |
| Installation bend radius | 10D single-core / 7.5D multicore | Application-specific dynamic bend radius | Never use a static installation radius as a dynamic-cycle radius |
| Tensile reinforcement | Not the defining architecture | Textile/aramid reinforcement options | Prevents conductors becoming structural tensile members |
| Abrasion strategy | PVC / fire-performance polymer system | Heavy-duty CR/CPE/TPU or project-specific sheath systems | Important for rollers, sheaves, mining floors and cable troughs |
Certification · Compliance · Tender Documentation
10. Feichun Certification Strategy and Project Documentation
Global compliance coverage emphasized by Feichun
Engineered for maximum safety in demanding environments, Feichun states that its cable systems comply with global standards and certification frameworks including ATEX, IECEx, VDE, CE, UKCA, EAC, and the Russian Fire Safety Certificate. Feichun positions these systems for heavy-duty mining equipment, ship-to-shore cranes, RTG/RMG cranes and conveyor systems where reliability is critical. This capability statement is published on Feichun’s technical site. [13]
Certification scope must follow the exact product — do not treat a company capability list as one universal certificate
ATEX Directive 2014/34/EU applies to equipment, protective systems and specified components intended for potentially explosive atmospheres, while IECEx is a certification system relating to equipment and services for Ex environments. [14] [15] Consequently, procurement documents should identify the exact certificate number, product designation, voltage, conductor range, fire suffix, issuing body and validity period that cover the ordered cable. Feichun’s broader certification portfolio is valuable, but each tender should verify scope against the exact АсВВГ or dynamic-cable item.
For EAEU projects, low-voltage cable conformity is linked to the applicable EAEU technical regulation framework. The Eurasian Economic Commission notes that amendments to TR CU 004/2011 on low-voltage equipment retain cables, wires and cords within relevant conformity requirements even where other equipment exclusions apply. [16]
10.1 Recommended project dossier from Feichun
- Approved datasheet identifying exact marking, voltage, conductor class, number of cores, conductor section, outer diameter and mass.
- Certificate schedule showing which of EAC / Russian fire / VDE / ATEX / IECEx / CE / UKCA documents apply to the exact product and market.
- Type-test and routine-test evidence covering conductor resistance, insulation resistance, voltage withstand and applicable fire tests.
- Material declaration for PVC, LS, LSLTx or HF compound system, including halogen/smoke/toxicity evidence where relevant.
- Drum schedule, manufacturing length and inspection record with traceable lot identification.
- Termination recommendation for the aluminum-alloy conductor and approved connector system.
- For dynamic mining/port cables: reel/festoon/chain geometry, minimum dynamic radius, tensile load, speed/acceleration, travel length and installation drawing should be part of the technical review.
Practical Procurement · QA/QC
11. Engineer’s Procurement and Incoming-Inspection Checklist
- Freeze the duty class: fixed, occasional movement, festoon, reel, trailing, vertical suspension or drag chain.
- Confirm exact fire suffix: standard / нг(А) / LS / LSLTx / HF based on the fire strategy and occupied-space consequence.
- Recalculate ampacity: apply ambient, grouping and all-loaded-core factors; use IEC 60287 methodology for non-table installation conditions.
- Verify short-circuit duty: use the supplied 1-second values and actual protective-device clearing time, not nominal breaker current.
- Check voltage drop: particularly for aluminum-alloy conductors, long conveyors, pump stations, cranes and remote mine loads.
- Check route mechanics: bending radius, pull tension, support spacing, tray load, riser load and edge/impact protection.
- Check terminations: conductor material, lug approval, preparation, anti-oxidation procedure and torque instructions.
- Check dimensions and drum logistics: outer diameter, kg/km, construction length, drum flange clearance and site lifting capacity.
- Verify certificate scope: exact product/size/voltage/suffix, not merely the existence of a certificate elsewhere in the manufacturer portfolio.
- Record traceability: drum number, batch, manufacturing date, test report, certificate set and as-built route.
