RHEYFIRM® is Nexans' premium line of flexible medium-voltage reeling cables specifically engineered for the extreme mechanical and environmental stresses of port machinery (STS cranes, automated stacker-reclaimers) and mining equipment (continuous dragline cables, mobile crusher power systems). Unlike fixed installation cables that remain stationary throughout their service life, reeling cables experience constant dynamic stress—deploying and retracting hundreds to thousands of times over their operational life. This continuous reeling duty subjects the cable to millions of bending cycles, sustained tensile loads, electromagnetic stress, salt spray corrosion, intense ultraviolet radiation, and temperature extremes far exceeding what conventional industrial cables are designed to tolerate. The physical diameter of a reeling cable is not simply a matter of aesthetics or standardization—it directly affects how much cable can fit on a physical drum of fixed dimensions. Consider a stacker-reclaimer with an existing cable drum that has a fixed flange width (say, 1,200 millimeters) and a fixed core diameter (say, 400 millimeters). The amount of cable that can be wound onto this drum depends on how tightly the cable packs around the core. A cable with a 59-millimeter outer diameter will create a larger spiral as it is wound layer by layer, limiting the total cable length to perhaps 600 meters. That same physical drum, if fitted with a 55.8-millimeter diameter cable, creates a tighter spiral and accommodates perhaps 750 meters of cable—a 25 percent increase in usable length with zero change to the physical equipment. For equipment where travel distance requirements have increased due to terminal expansion or operational upgrades, this diameter optimization can mean the difference between being able to extend operations and being forced into an expensive drum replacement project costing hundreds of thousands of dollars.

Mining operations face persistent safety challenges, with powered haulage accidents accounting for approximately 50% of all mining-related fatalities annually in the United States. Among these incidents, haul truck-related accidents remain the most prevalent, with six out of twenty-eight mining fatalities in 2017 and six out of twenty-seven in 2018 being directly attributed to haul truck operations. The introduction of self-illuminating LED-integrated mining cables represents a transformative advancement in collision avoidance technology, specifically addressing the critical issue of cable run-over accidents in low-visibility environments. （矿山作业面临持续的安全挑战，在美国，动力运输事故约占所有矿山相关死亡事故的50%。在这些事故中，运输卡车相关事故最为普遍，2017年28起矿山死亡事故中有6起、2018年27起中有6起直接归因于运输卡车作业。自发光LED集成矿用电缆的引入代表了防碰撞技术的变革性进步，专门解决低能见度环境中电缆碾压事故的关键问题。）

In large-scale open-pit mines and underground operations, heavy mobile equipment — electric rope shovels, walking draglines, blast-hole drill rigs, and haul trucks — operates around the clock, including night shifts and in environments with zero natural light. Trailing power cables that supply electricity to this equipment lie across haul roads and bench floors, often spanning hundreds or even thousands of meters. When operators cannot see these cables, the result is crushover damage, unplanned downtime, and in the worst cases, life-threatening electrical faults. Cable damage from equipment runover is one of the most persistent operational challenges in surface mining. Each crush event can take a mine's primary production asset offline for hours or even days while the cable is repaired or replaced, and a damaged medium-voltage cable carrying 6 kV to 25 kV poses a serious arc-flash and electrocution hazard to any personnel nearby. According to Prysmian Group, the origin of many unplanned mining interruptions is related to power cable damage caused by equipment crushing during movement, particularly due to visibility restrictions. 据普睿司曼集团介绍，许多矿山非计划停机的根源是设备移动过程中因能见度受限导致的电力电缆压损。

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。

Load-Haul-Dump (LHD) loaders are the backbone of underground ore movement—more than 75% of the world's underground metal mines rely on LHDs for material handling. Electric-motor LHD units typically operate at medium voltages of 380–550 V (and up to 3.3/6.6 kV for larger units), drawing power through flexible trailing cables that must reel and unreel as the machine moves through narrow, irregular headings. In the permanent darkness of underground drifts, these cables face an acute visibility problem: personnel and equipment cannot easily see trailing cables on the ground, leading to run-over damage, unplanned outages, and serious safety hazards.

In large-scale open-pit mining, unplanned cable damage caused by low-visibility equipment movement is a leading source of operational downtime and safety incidents. The TENAX-LUMEN self-illuminating trailing cable—designated (N)TSCGEH3S—was developed by Prysmian Group precisely to address this problem. It embeds active electroluminescent (EL) lighting elements under a transparent polyurethane (TPU) outer sheath, making the cable visible in complete darkness even when it is not energized. But an essential question arises for mine electrical engineers: does adding self-illumination change the cable's core mechanical and electrical characteristics compared to the well-established (N)TSCGEWÖU standard rubber trailing cable?
