应用工况
TYPE G-CGC 2000 V un屏蔽 mining 拖曳电缆 combining a central extensible yellow PP 接地监测 导体, three rope-lay 镀锡 铜 EPR phase 导体s, three symmetrical green grounds 与 a two-layer reinforced black CPE jacket.
Central extensible 接地监测 core sits on the neutral bending axis 至 eliminate pilot-wire breakage during trailing.
Three symmetrical interstitial grounds provide balanced low-impedance fault return 与 balanced roundness.
Two-layer reinforced CPE jacket 配有 embedded cord braid resists shuttle-car sheave tension 与 run-over.
