摘　　要：以2014-2015年石家庄市配网电缆的故障数据为研究对象,从中间头生产质量、安装工艺和运行环境等方面介绍电缆中间头故障的原因,结合实际运行经验,对电缆中间头的故障时间分布规律及浴盆曲线进行分析。提出不同电缆故障时间段的预防措施,以降低电缆故障率。at present, the number of Shijiazhuang distribution cable is becoming more and more, so how to effectively control the number of cable fault-became a big problem.This paper is based on the data of Shijiazhuang distribution cable＇s fault in 2014-2015, consider to the quality of accessories and installation process and running environment, and combines with the actual op- eration experience,preliminary discussed the fault time distribution of cable joint, and put forward the tub curve.Finally, accord ing to the different time , put forward the corresponding solutions in order to reduce cable fault rate.

关 键 词：电缆中间头 故障规律 浴盆曲线 预防措施
