    电缆输送机发生故障的原因有以下几个情况: 机械损伤、绝缘受潮、绝缘老化、化学腐蚀、过热击穿、材料缺陷、过电压击穿。可概括为接地、短路、断线三类, 其故障类型主要有以下几方面:
①三芯电缆一芯或两芯接地。
②二相芯线间短路。
③三相芯线完全短路。
④一相芯线断线或多相断线。

The reason of failure has the following situation: mechanical damage, be affected with damp be affected with damp insulation, insulation aging, chemical corrosion, hot breakdown, material defects, over-voltage breakdown.Can be summarized as grounding, short circuit, break three types, the fault types mainly include the following aspects:Three core cable (1) a core or two core grounding.(2) two phase short circuit between conductor.(3) three phase conductor short-circuit completely.(4) a phase conductor wire break or multiphase break line.
