摘　　要：光纤复合架空地线(OPGW)的架设依附于电力线路,是具有普通架空地线和光纤通信能力双重功能的特种光缆。除应遵照架空输电线路设计规范进行设计外,还应满足OPGW的设计技术规定。通过对OPGW和良导体地线短路电流能力、抗雷击断股能力分析及对过载能力计算和比较,提出了在选择OPGW和良导体地线时应注意的几个问题。The erection of OPGW is attached to the power transmission lines,OPGW is a special fiber optic cable with the dual function of the general overhead ground wire and fiber optic communications capabilities.The design should not only follow the design of specifications of overhead transmission lines,but also meet the technical requirements of OPGW.The writer,through analyzing the short-circuit current capacity of OPGW and good conductor,estimating the anti-lightning off shares capacity,making some calculation and comparison of the overload capacity of OPGW and a good conductor ground wire,suggests several key technologies in the selection of OPGW and good conductor ground wire.
