摘　　要：介绍了光纤复合架空地线（OPGW）光缆在国内第一个超高压西北750kV官亭-兰州东输电线路的应用。结合西北750kV输电线路的特点和对OPGW的要求，描述了750kV输电线路OPGW光缆的结构设计的特点，同时通过750kV官亭-兰州东输电线路大档OPGW光缆防振特性的研究，为西北750kV输电线路1235m大档距OPGW光缆推荐了满足技术条件的直线档防振方案，并提供了测试结果及分析意见，对探索和积750kV超高压等级上OPGW光缆的设计和运行经验具有现实意义。This paper presents the application of OPGW optical cables in the first extra-high voltage power line of 750 kV from Guanting to Lanzhou east. Based on characters of 750 kV power transmission line and technical requirements on OPGW, structure design characteristics of OPGW optical cable in 750 kV transmission line are described. Researches on the shockproof character of large-span OPGW optical cables in 750 kV power transmission line from Guanting to Lanzhou east provide linear-span shockproof scheme which meets the specification for 1 235 m large-span OPGW optical cables in Northwest 750 kV power grid. The test results and analyses are presented, which has a practical significance for investigating and accumulating experiences on OPGW optical cable design and operation of 750 kV extra-high voltage level.
