摘　　要：架空地线复合光缆O(PGW)作为电力系统的重要组成部分,广泛地应用在架空输电线路上,兼具着架空地线和光纤通信双重功能,在电力系统中起着防雷保护和传输信息的作用。通过OPGW光缆雷击断股现象和雷击断股机理的分析,得出OPGW光缆雷击断股的内因和外因。并从输电线路的设计、OPGW光缆的选型设计和运行维护等方面综合考虑,对如何提高OPGW光缆的耐雷水平作一些探讨。OPGW is an important element of electrical power system, it is not only used for ground wire against lighting strike to protect transmission line, but also as fiber optic cable to transmit information. In this article we analyze some examples of OPGW and find out t.he inner and external reasons of lightning-caused OPGW strand breakage. We also discuss how to improve OPGW performance against lighting strike in some aspects such as transmission line design, the OPGW types selection and OPGW maintenance.
