摘　　要：输电线路走廊已越来越多采用紧凑型输电线路为骨干网架。文章介绍了500 kV紧凑型输电线路4×LGJ-400/35和6×LGJ-240/30两种导线布置方式,通过综合比较两种导线布置方式的自然功率、走廊宽度、导线表面场强、防雷性能等电气性能,推荐采用6×LGJ-240/30导线布置方式,具有良好的经济性。More and more compact transmission hnes are adopted as backbone wire frames of transmission line corri- dors. The paper introduces two layout modes of 4 ×LGJ-400/35 and 6× LGJ-240/30 for 500kV compact transmission line, and the layout mode of 6 × LGJ-240/30 is suggested based on comprehensive comparison of the surge impedance loading, the corridor width, the surface field of conductor, the lightning protection performance and other electrical performances of the two layout modes, which has good economy.
