Why does VDE 0250 mandate an inner semi-conductive layer for all rubber cables rated 6kV and above?

In the DIN VDE 0250-813 standard, the majority of reeling cables supplied are the standard (N)TSCGEWÖU, which utilizes 3 Earth Cores located in the interstices for grounding. However, for critical safety applications and high-fault-risk environments, the (N)TSCGECEWÖU variant is engineered with Individual Metallic Screens (Copper Braid) surrounding each phase core. You should select this cable when your safety protocols require individual phase earth-fault monitoring or when operating in environments where phase-to-phase short circuits must be mechanically prevented. 在 DIN VDE 0250-813 标准中，供应的大多数卷盘电缆是标准的 (N)TSCGEWÖU，它利用位于缝隙中的 3 根接地芯进行接地。然而，对于关键的安全应用和高故障风险环境，(N)TSCGECEWÖU 变体在设计上采用了环绕每个相芯的独立金属屏蔽（铜编织）。当您的安全协议要求进行独立分相接地故障监测，或者在必须机械防止相间短路的环境中操作时，您应该选择这种电缆。
