Medium Voltage Cable

In VDE mining cable standards, particularly DIN VDE 0250-813 and DIN VDE 0250-814, the outer sheath color serves as a critical visual identifier that indicates the cable’s intended application environment and specific performance characteristics. The red sheath is the standard color for open-pit (surface) mining cables manufactured with PCP (Polychloroprene) compound type 5GM5, providing maximum UV resistance and high visibility in outdoor environments. Black sheaths are typically used for underground mining and general industrial applications where UV protection is less critical. Yellow sheaths indicate either high-visibility safety cables or specialized trailing cables for coal cutting machines, also commonly manufactured with premium TPU (Thermoplastic Polyurethane) compounds for extreme abrasion resistance.[1][2][3] 在VDE矿用电缆标准中，特别是DIN VDE 0250-813和DIN VDE 0250-814，外护套颜色是关键的视觉标识符，指示电缆的预期应用环境和特定性能特性。红色护套是使用PCP（氯丁橡胶）5GM5型化合物制造的露天（地面）矿用电缆的标准颜色，提供最大的抗紫外线能力和户外环境的高可见性。黑色护套通常用于井下矿业和对紫外线防护要求较低的一般工业应用。黄色护套表示高可见性安全电缆或用于采煤机的专用拖曳电缆，通常也采用优质TPU（热塑性聚氨酯）化合物制造以获得极高的耐磨性。
