摘　　要：大跨越导线选型是大跨越设计的关键技术,导线特性决定了跨越塔的高度和运行张力,并对线路运行安全、工程造价水平具有重要意义。从电气性能、机械性能和投资分析三个方面对各种导线进行详细技术经济比较,选定最优的导线截面积和分裂型式,为工程设计提供依据。通过对已有大跨越导线应用现状的分析,结合工程实际特点,推荐采用JLHA1/G4A-900/240特强钢芯高强铝合金绞线,每极导线4分裂,分裂间距600 mm。Wire selection of long span is the key technology of large span crossing design,the characteristics of the wire determines the height of the tower,the operating tension,the line operation safety,and the engineering cost.Detailed technical and economic comparisons of various conductors are made from three aspects of electrical performance,mechanical performance and investment analysis,the optimal sectional area and splitting type of the conductor are selected to provide the basis for engineering design.By analyzing the application status of existing large span conductor,combined with the actual characteristics of the project,it is recommended to use JLHA1/G4 A-900/240 super strong steel core high-strength aluminum alloy wire,each pole wire 4 split,split spacing 600 mm.
