4ד一牵2”1250 mm^2大截面导线直线塔放线滑车悬挂方式

4 × “one pull 2” 1250 mm^2 Large-section Wire Linear Tower Wire Hanging Block Mode

增加导线分裂数、加大导体等效直径、提高输送容量、降低电晕、减少电抗,是特高压电网建设的发展趋势。基于4×"一牵2"导线展放方法,结合现有机具设备和安装工艺,论证制定了八分裂导线放线滑车悬挂方案,并在昌吉-古泉±1 100 kV特高压直流输电工程6 B标段应用,实现导线架设综合效益最大化。

Increase the number of wire spilt,increase the equivalent diameter of the conductor,improve the transportation of electric capacity,lower wire corona,reduce wire reactance is that development trend of UHV power grid construction.Based on the 4דone pull 2”conductor lay out method,combine with existing machines&equipments and installation technology,demonstrating and formulating the eight splitting conductor laying block suspension scheme,as well as using in the Changji Guquan±1 100 kV UHVDC power transmission project 6B section,achieve maximum comprehensive benefits of wire erection.
