摘　　要：随着电力电缆线路负荷电流、运行环境温度、敷设方式的变化,电力电缆会发生热伸缩,影响电力电缆运行时的热稳定性,对电力电缆安全稳定运行造成很大的威害。Along with the change of the load current, operation environmental temperature and laying mode of the power cable line, the power cable w;U appear thermal expansion and contraction, which affects the thermal stability of the power cable operating, threatens the safe operation of the power cable.
