On the other hand, electric power communication system is easy to damage and cause losses because of its poor resistance to lightning overvoltage. Once there is lightning strike and failure in electric power communication system, it will cause interruption or dispatching system paralysis, and then causing blackouts and other accidents. Therefore, for the electric power communication, the harm of lightning is not to be ignored and must be solved. Combinedwith concrete practice experience,this paper sumsup the three principles inthe process of electric power communication systemlightning protection design: integratedlightning protection, scientificandeffective andeconomical, inorderto achievethe purpose of protection ofelectricpower communication systemanditsequipment. 防雷；设计；原则 关键词院电力；通信系统； Keywords: electricpower；communication systems；lightning protection；design；principle 中图分类号院TM734 文献标识码院A 文章编号院1006-4311（2015）12-0133-04 ，电力通信系统 （
