大截面空心扩径导线的安装及质量验收

Installation and Quality Inspection of Large Cross-Section Diameter Expanded Hollow Wire

大截面空心扩径导线由于外径的扩大,使其在运行中具有减少导线表面电场强度、减小无线电干扰、载流量大且节能环保等众多优点,是超高压和特高压输电线路工程的重点产品。但空心扩径导线的特殊结构,也使其安装有别于普通的钢芯铝绞线的安装。为此,对大截面空心扩径导线的安装过程以及安装质量验收规范进行了详细介绍。

Due to the diameter expanded, large cross-section diameter expanded hollow wire has such advantages as reduced conductor surface electric field strength, reduced radio interference, large current-carrying capacity, energy saving, and environmental protection. So it is the key product in the EHV and UHV transmission line projects. However, due to its specific structure, its installation is different from that of ordinary steel core aluminum stranded wire. Consequently, the installation process and the installation quality acceptance specification for the wire are introduced in detail.
