Nexans POWERMINE cable

Consider a medium-voltage mining trailing cable — for instance, an (N)TMCGEH3S rated 6/10 kV — carrying hundreds of amperes of alternating current through its three power cores to an electric rope shovel in an open-pit mine. Somewhere inside the same cable, a tiny LED glows steadily, making the cable visible to operators in darkness. Yet that LED has no wire, no contact, no physical electrical connection to the power cores. How is this possible? 设想一根中压矿用拖拽电缆——例如额定 6/10 kV 的 (N)TMCGEH3S——通过三根动力线芯向露天矿的电铲输送数百安培的交流电。在同一根电缆内部某处,一颗微小的 LED 稳定发光,使电缆在黑暗中对操作人员可见。但该 LED 与动力线芯之间没有导线、没有触点、没有任何物理电气连接。这是如何做到的?

Underground LHD (Load-Haul-Dump) loaders — also called scooptrams — rely on a flexible trailing cable that is continuously reeled and unreeled as the machine travels between muck piles and ore passes. The cable must survive thousands of reeling cycles, simultaneous tensile and torsional loads, crushing from rock debris, and exposure to water, oil, and abrasive dust. Two cable families dominate this niche: the Nexans TORERO® series (type designation NSHTOEU) and the more generic NSSHÖU heavy-duty rubber cable. 井下 LHD(铲运机/Scooptram)依靠持续收放的柔性拖曳电缆供电。该电缆需承受数千次卷绕循环、拉伸与扭转同时作用的载荷、岩石碾压以及水、油与粉尘侵蚀。两大系列电缆在此领域占据主导:Nexans TORERO®(型号 NSHTOEU)与通用的 NSSHÖU 重型橡套电缆。 This article explains the structural, electrical, and mechanical differences between the two, examines why many OEMs and mine operators specify the TORERO type for LHD duty, and introduces Feichun's comparable alternative manufactured in Anhui, China. 本文将阐明二者在结构、电气与机械性能上的差异,分析 OEM 与矿方为何为 LHD 工况指定 TORERO 型,并介绍飞纯在安徽制造的同等替代方案。
