While most people associate mining cables with black rubber sheaths being dragged behind excavators (like the (N)TSCGEWÖU series), there is a critical class of cables designed for "shiftable" or fixed equipment in hazardous tunnel environments. This is where (N)3GHSSYCY dominates. Defined by DIN VDE 0250-605, this PVC-sheathed, steel-braided medium voltage cable is engineered specifically to feed power to TBMs (Tunnel Boring Machines) and massive transformers. Its unique internal geometry makes it the superior choice for Variable Frequency Drive (VFD) applications, solving issues of electromagnetic interference (EMI) that standard cables cannot handle. 虽然大多数人将矿用电缆与拖在挖掘机后面的黑色橡胶护套（如 (N)TSCGEWÖU 系列）联系在一起，但也有一类关键的电缆是专为危险隧道环境中的“可移动”或固定设备设计的。这就是 (N)3GHSSYCY 占据主导地位的领域。该电缆由 DIN VDE 0250-605 定义，采用 PVC 护套和钢丝编织，专门用于为 TBM（全断面隧道掘进机）和大型变压器供电。其独特的内部几何结构使其成为变频驱动 (VFD) 应用的绝佳选择，解决了标准电缆无法处理的电磁干扰 (EMI) 问题。
