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？

TENAX-LUMEN represents a breakthrough in mining cable safety technology. This self-illuminating medium voltage trailing cable features embedded electroluminescent strings that provide 360° continuous illumination, ensuring cable visibility in complete darkness. The cable remains visible even when not energized, dramatically improving safety for personnel and equipment in mining operations where lighting may be compromised or unavailable. TENAX-LUMEN代表了矿用电缆安全技术的突破。这种自发光中压拖曳电缆具有嵌入式电致发光线，提供360°连续照明，确保在完全黑暗中电缆的可见性。即使在未通电的情况下，电缆仍然可见，大大提高了在照明可能受损或不可用的矿业作业中人员和设备的安全性。
