架空配电线路导线发展应用概述

Development and Application of Overhead Distribution Line Conductor

配电架空线路导线作为连接变电站与用户的主要媒介,其安全稳定性对供电可靠性有重大影响。文章按照架空导线的发展顺序,从裸导线、绝缘导线、中强度铝合金芯绝缘导线以及铝包钢芯铝绞线等方面介绍了近年来架空配电线路导线的研究和应用成果,为今后架空导线的发展提供参考。

As the main medium connecting substation and users,the safety and stability of distribution overhead line conductor has a signifi cant impact on the reliability of power supply.According to the development sequence of overhead conductor,this paper introduces the research and application results of overhead distribution line conductor in recent years from the aspects of bare conductor,insulated conductor,medium strength aluminum alloy core insulated conductor and aluminum clad steel core aluminum strand,so as to provide reference for the development direction of overhead conductor in the future.
