摘　　要：基站的电力电缆都穿行在山林中,发生故障后,故障点查找困难。文中介绍电缆故障位置的计算方法,利用环阻、电缆线径和环境温度计算出故障位置,并按照计算方法制作出环阻、温度和电缆故障位置长度对应表。The power cable of base station through the trees, the mountains, it is difficult to find fault point when oc- cur failure. With ring resistance and cable diameter and environment temperature can calculate the fault location, this paper introduced the calculation method of cable fault location, and according to the calculation method, made the corresponding table for loop resistance, temperature and length of cable fault location.

关 键 词：环阻 温度 电阻率 长度
