冷缩电缆终端头故障分析

Failure analysis of the cold contraction cable head

通过对某供电局连续发生的两起10kV电力电缆终端头由于制作工艺不到位引起的单相接地故障的剖析,制定防范措施,规范电力电缆终端头制作工艺,力求避免电缆终端头故障的再次发生。

Analyzes two cases which cause the 10 kV power cable head occurring the single phase grounding failure due to unsuited manufacturing technique in a power supply bureau, makes up the preventive measures and the manufacturing technique criterions of power cable head, tries to avoid the failure of power cable head happening.
