摘　　要：近年来,国内的光纤复合架空地线光缆OPGW光缆出现了多次雷击断股的事件,一些解决方案强调从系统设计方面来着手解决这一问题。从雷击理论来分析,常规的防雷措施是不能提高OPGW的抗雷击水平的。文章从线路的角度出发,对这一事件进行分析,并提出解决措施。In recent years, the incidents of broken strand of OPGW cable by lightning stroke at home are occurred for many times, some solving schemas are emphasized from system design aspect to solve this problem. Analysis from theory of lightning stroke shows that conventional measures for prevention of lightning cannot improve the level of lightning prevention of OPGW. This paper analyzes the incident from the view of line, and puts forward the solving measures.
