摘要

针对某现场运行的超高压线路OPGW频繁断股的问题

通过对该OPGW样品的理化性能、雷击性能、短路电流性能等的试验与分析

结合该线路运行情况

得出该OPGW断股由雷击造成

而该OPGW本身耐雷性能较差。

Abstract

For frequent OPGW strand breakage of an EHV transmission line

the physical and chemical properties

anti-lightning performance

and short-circuit property are tested and analyzed.Considering the operation condition of the transmission line

conclusion can be drawn that the strand breakage of the OPGW is caused by lightning

and anti-lightning performance of the OPGW is weak.
