节能导线对输电线路标准设计杆塔的经济适用性分析

Economic applicability analysis of energy-saving conductor for transmission line standard design tower

依据第三届南方电网公司基建"金点奖"大赛绿色线路节能导线方案设计输入条件清单要求(220 kV为同塔双回、每回正常最大负荷305 MVA、海拔1 000 m^1 500 m、基本风速25 m/s(离地面10 m)、覆冰厚度10 mm,按山地行规划设计)进行分析论证。

This paper analyzed and demonstrated the transmission line energy-saving conductor project design input condition list requirement（ 220 kV with common-tower double-transmission lines, each line normal maximum load of 305 MVA, altitude of 1 000-1 500 m, basic wind speed of 25 m/s（ 10m from the ground）, ice thickness of 10 ram, according to mountainous region guild regulations design） based on the third session of Southern Power Grid Company infrastructure＂ Jindian Award＂ competition.
