摘要
500kV花都—博罗输电线路工程,采用ACSR-720/50大截面导线,四分裂,同塔双回路。该工程采用一牵四方式放线,相对于以前的一牵二方式放线,可以消除一牵二带来的质量隐患,而且具有易于弧垂观侧、调整,附件安装工艺简单,施工效率高等优点,是一种理想的放线方式。
4 - bundled, ACSR - 720/50 large - section conductor and double - circuit towers were used in Huadu - Boluo 500 kV transmission line project. One - pull - four stringing technique was used in this project. Compared to old one - pull - two method, the new technique has many advantages, such as easy sag observation and adjustment, simple accessory installation, and higher construction efficiency, etc. It is an ideal stringing method.
