An engineering-grade technical reference for mining electrical engineers, EPC contractors, OEM equipment manufacturers, and procurement specialists selecting high-flexibility trailing cables for underground and surface mining operations in Russia and CIS markets. This document presents the structural engineering, material science, and certification architecture of Feichun’s (N)TSCGEWÖU-FO mining trailing cable — a purpose-designed construction combining extreme tensile reinforcement, multi-layer abrasion resistance, integrated fibre-optic monitoring, and dual EAC Ex / GOST-R fire certification within a single cable assembly engineered for the most demanding dragline, continuous miner, shuttle car, and longwall shearer applications operating under Russian Federal mining safety regulations.
Mining operations present unique challenges unlike any other industrial environment. Workers operate deep underground in near-total darkness, often hundreds of metres below the surface where natural light cannot penetrate. Traditional lighting systems rely on external power sources—separate electrical circuits, portable lamps, headlamps—adding cost, complexity, and dependency on supplementary infrastructure. A single power outage can plunge the entire mining operation into complete darkness, creating dangerous working conditions.
The SUPREMINE® LED Self-Luminous Mining Cable introduces a paradigm shift in mining cable technology. By integrating advanced electromagnetic induction self-powered LED illumination directly into the cable structure, SUPREMINE LED delivers continuous, self-sustaining illumination wherever the cable is deployed—with zero reliance on external power sources, no additional wiring, and zero maintenance overhead.
The cable itself becomes the light source. As electrical power flows through the medium voltage conductors (6–30 kV), the resulting magnetic field is converted through proprietary electromagnetic induction circuitry into LED illumination along the entire cable length. The innovation combines DIN VDE 0250-813 mining cable compliance with breakthrough photonic energy harvesting technology, creating an indispensable safety and visibility solution for the world’s most demanding underground mining applications.
TENAX-V (Prysmian/Draka) — стандарт немецких угольных комбайнов: Prysmian TENAX-V — торговая марка специализированного кабеля, разработанная для электропривода современных угольных комбайнов (“Comba” в немецкой терминологии, “Schräm” — резчик-погрузчик, “Continuous Miner” в англосаксонской терминологии). TENAX-V используется в подземных угольных шахтах Германии, Польши, Украины, России (исторически), а также в государствах Донбасса (Донецк, Луганск до 2022 года). Исторический контекст: в течение 1990–2010-х годов, крупные российские и украинские угольные операторы (Metabats, DTEK, Gazprom Dobycha Uchta) импортировали немецкие электрооборудование (включая комбайны Vogele, Krupp, Joy Global) вместе с их стандартными кабелями TENAX-V от Prysmian. Эта техника остаётся в операции, требуя замены электрических компонентов (кабели деградируют за 8–12 лет в условиях угольной шахты). Post-2022 (санкции): прямые закупки TENAX-V от Prysmian невозможны; операторы ищут русские эквиваленты.
In underground coal mining across Australia and New Zealand, selecting between AS/NZS 1802 and AS/NZS 1972 is not a matter of personal preference or cost optimization—it is a matter of electrical safety compliance and regulatory requirement. The decision tree, however, is surprisingly straightforward once you understand the single fundamental principle that separates these two standards: whether your equipment moves while energized.
在澳大利亚和新西兰的地下煤矿电气设计中,在AS/NZS 1802和AS/NZS 1972之间选择不是个人偏好或成本优化的问题——这是电气安全合规性和监管要求的问题。然而,一旦您理解分离这两个标准的单一基本原则,决策树就会变得出奇地直接:您的设备在通电时是否移动。
The central pilot core in an AS/NZS 1802 Type 241 6.6/6.6kV 3x120mm² cable should exhibit a measured DC resistance of approximately 0.350 to 1.050 ohms per kilometer at 20°C, depending on the pilot conductor’s specific cross-sectional area (typically 16mm² or 25mm² in this cable class). For a typical 1,000-meter installation cable segment, the measured resistance across the entire pilot conductor pair (measuring between one end and the remote end, or using a calculated pro-rata method for field acceptance) should not exceed 1.050 ohms for a 16mm² pilot, or approximately 0.690 ohms for a 25mm² pilot. These resistance values serve as acceptance criteria for cable deliveries and provide a baseline against which future field testing can detect degradation caused by moisture ingress, oxidation, mechanical damage, or other environmental stress. The pilot core must demonstrate electrical continuity (resistance approaching zero would indicate an open circuit) while remaining within the specified upper bound (excessive resistance would indicate partial failure or contamination). Testing is performed using a standard digital multimeter set to resistance/ohms mode or using a dedicated cable tester with DC ohmmeter functionality, applied across the pilot conductor terminals at each cable end.
The primary difference between AS/NZS 1802 Type 241 and Type 245 mining cables lies in their internal core configuration and the resulting mechanical flexibility characteristics. Type 241 contains three power cores, three interstitial grounding cores, and one central extensible pilot core (total of seven conductors), while Type 245 contains three power cores, three interstitial grounding cores, and three central extensible pilot cores (total of nine conductors). This seemingly modest difference—replacing one central pilot with three parallel pilots—fundamentally changes how the cable bends, flexes, and responds to the mechanical stresses of underground mining operations. Type 241 is the standard general-purpose feeder cable designed for continuous miners, pump power supplies, and applications where the cable experiences moderate, repetitive flexing but does not encounter the extreme bending and twisting stresses of longwall operations. Type 245 is the high-flexibility shearer cable engineered specifically for longwall shearers and other equipment that demands superior resistance to severe, repetitive bending and the complex rotational stresses that characterize modern longwall mining systems.
When electrical engineers and equipment operators discuss the capacity of a dragline or shovel reeling cable, they often refer to a specification that seems disconnected from the typical electrical characteristics — the maximum permissible tensile load, expressed in units of pounds per thousand circular mills (lbs/mcm). This specification is fundamentally different from ampacity (which measures the cable’s ability to safely carry electrical current) or voltage rating (which specifies the insulation quality). Instead, tensile load capacity describes the maximum mechanical force that the cable can withstand before the metallic conductors themselves begin to yield, stretch, or break. For a reeling cable used on heavy dragline or shovel equipment, this mechanical specification is often more critical to equipment safety and service life than the electrical specifications, because the cable is typically exposed to enormous pulling forces that can exceed the weight of the equipment being supported.
Modern mining operations increasingly rely on self-illuminating cables to improve safety visibility in underground environments. By embedding LED strip lights directly within the transparent or translucent thermoplastic polyurethane (TPU) outer jacket of a trailing or reeling cable, operators gain continuous visual confirmation of cable routing, reduce tripping hazards, and can detect cable damage more readily. Anhui Feichun Special Cable Co., Ltd. has pioneered this approach in its SHD-GC LED Mining Cable series, integrating constant-current LED strips into cables rated from 2 kV to 25 kV for both underground and open-pit operations.
现代矿山作业越来越依赖于自发光电缆来提高地下环境的安全可见度。通过将LED灯带直接嵌入拖曳或卷缆的透明/半透明热塑性聚氨酯(TPU)外护套中,操作人员可持续确认电缆走向路线、降低绊倒风险,并更容易检测电缆损坏。安徽飞纯特种电缆有限公司在其SHD-GC LED矿用电缆系列中率先采用了该技术。

Australia’s mining industry operates under stringent safety regulations, particularly for underground coal operations where methane gas and coal dust present unique explosion hazards. The selection of appropriate electrical cables is not merely a technical decision but a critical safety requirement mandated by New South Wales Work Health and Safety regulations. According to the Work Health and Safety (Mines and Petroleum Sites) Regulation 2022, specific cable types must be used in hazardous zones of underground coal mines to prevent catastrophic incidents.

In the demanding environment of underground coal mining operations, electrical cable safety is not merely a regulatory checkbox—it represents a fundamental commitment to worker protection and operational reliability. When evaluating cable manufacturers for compliance with the Australian and New Zealand Standard AS/NZS 1802, the presence of a NATA-accredited test report serves as the gold standard of verification, providing independent assurance that cables meet stringent safety requirements designed specifically for hazardous underground coal mining conditions.

In the global cable manufacturing industry, voltage ratings represent a fundamental specification that determines a cable’s safe operating parameters and application suitability. When examining low-voltage mining cables, a notable discrepancy emerges between international standards and those used in Australia and New Zealand. While the International Electrotechnical Commission (IEC) designates low-voltage power cables with a rating of 0.6/1kV under IEC 60502-1, Australian mining standards specify a 1.1/1.1kV rating for equivalent applications. This distinction is not arbitrary but reflects careful consideration of mining-specific operational requirements, safety margins, and the unique characteristics of Australia’s mining infrastructure.
在全球电缆制造行业中,电压等级是决定电缆安全运行参数和应用适用性的基本规格。在研究低压矿用电缆时,国际标准与澳大利亚和新西兰使用的标准之间存在明显差异。国际电工委员会(IEC)根据IEC 60502-1标准将低压电力电缆的额定值指定为0.6/1kV,而澳大利亚矿用标准对于同等应用规定了1.1/1.1kV的额定值。这种区别并非随意,而是反映了对矿山特定运行要求、安全裕度以及澳大利亚矿业基础设施独特特征的仔细考虑。
In underground coal mining operations, longwall shearers represent some of the most mechanically demanding equipment environments for electrical power cables. These massive machines, weighing between 75 and 120 tonnes, traverse coal faces while cutting mineral from seams at drum rotation speeds of 20 to 50 revolutions per minute, generating substantial vibration and mechanical stress on their power supply systems[1]. The selection between Type 241 and Type 275 cables for these applications involves understanding critical differences in construction, mechanical performance, and operational suitability under the AS/NZS 1802:2018 standard framework.

Underground coal mining operations in Australia present unique electrical safety challenges that require specialized cable systems and protection strategies. The presence of methane gas, coal dust, confined spaces, and high humidity creates an environment where electrical faults can potentially trigger catastrophic explosions. To mitigate these risks, Australian coal mines employ earth fault limitation systems that restrict fault currents to very low levels, typically 5 amperes (5A) for systems below 4,000 volts.
澳大利亚地下煤矿作业面临独特的电气安全挑战,需要专门的电缆系统和保护策略。甲烷气体、煤尘、狭窄空间和高湿度的存在造就了一个电气故障可能引发灾难性爆炸的环境。为降低这些风险,澳大利亚煤矿采用接地故障限制系统,将故障电流限制在非常低的水平,对于4000伏以下的系统,通常为5安培(5A)。
Longwall mining represents the most productive underground coal extraction method available to modern mining operations, with a single longwall face capable of producing over 5,000 tonnes of coal per hour in optimized installations. At the heart of this productivity lies the longwall shearer, a massive mobile machine that travels back and forth along the coal face, cutting coal with rotating drums while advancing through seam heights ranging from 1.6 to 7 meters. The power cables supplying electricity to these shearers operate in one of the most mechanically demanding cable applications in industrial engineering, subjected to continuous motion within cable chain systems (often referred to as “Bretby chains”), constant vibration from cutting operations, tight bending radii as the shearer traverses the face, and the harsh environmental conditions characteristic of underground coal mining.[1] (长壁开采代表了现代采矿作业可用的最具生产力的地下煤炭开采方法,单个长壁工作面在优化安装中每小时可生产超过5000吨煤炭)
Before we can properly discuss earthing techniques, we need to build a solid understanding of what (N)TSCGECEWÖU cables are and why their semiconductive screens require such careful attention.

Type 440 reeling cables represent a critical component in mining and industrial power distribution systems, specifically designed for flexible trailing applications according to AS/NZS 2802:2000 standards. These metal-screened power cables feature three pilot cores and operate across voltage ratings from 1.1 kilovolts to 11 kilovolts, supplying reliable electrical power to mobile mining equipment such as draglines, excavators, and materials handling machinery. Despite their robust construction with EPR insulation and high abrasion resistance, these cables remain vulnerable to a particularly destructive failure mode known as corkscrewing, which can compromise both electrical performance and mechanical integrity during operation.
Mining operations worldwide face a critical procurement decision when selecting medium voltage reeling and trailing cables for mobile equipment such as excavators, draglines, and continuous miners. The choice between premium brand-name cables like PROTOLON and generic alternatives conforming to the same NTSCGEWÖU specification represents a significant investment decision with long-term operational and safety implications.
When specifying medium-voltage mining cables for international projects, engineers frequently encounter seemingly incompatible voltage ratings between European VDE standards and Commonwealth AS/NZS standards. A common point of confusion arises when comparing the 3.6/6kV rating found in DIN VDE 0250-813 flexible mining cables with the 3.3/3.3kV rating specified for AS/NZS 2802 Type 441 cables used extensively in Australian, New Zealand, and South African mining operations.
