摘　　要：雷击光缆可造成金属构件熔化、针孔击穿和结构变形等,分析了光缆遭遇雷击的机理和概率,总结出地下光缆线路的雷电防护措施(路由的选择、地下防雷线、消弧线以及架空防雷地线的设置方法和要求)。Considering that lightning stroke results in melted metal piece of optical cable, pin hole breakdown and distorted structure, an analysis is made in this paper of mechanism and probability of lightning stroke against optical cable, and the paper summarizes lightning protective measures for underground optical cable line, including selection of routes, arrangement and requirements for lightning protection underground line, arc suppression coil and lightning protection overhead grounding line.

关 键 词：光缆线路 雷击 防护措施 针孔击穿 消弧线
