摘要
针对500kV电力线路增容改造工程,开发了一种新型增容导线——预应力处理超高强度(G4A)钢芯软铝绞线。该导线能够同时满足工程对增容、安装弧垂特性好、运行安全性好、可利用原有杆塔的要求,是一种安全可靠、资源节约型导线。
Aiming at the upgrading project of a 500 kV power line,a new type of capacity increasing conductor—prestressed processed ultra high strength（G4A）steel core aluminum stranded wire is developed.The conductor can meet a series of requirements,including capacity increasing,good sag property,good running safety,being able to use the original towers and poles,it is a kind of safe,reliable,and resource saving wire.
