摘要
介绍各种常用节能导线特点，分析110～500kV线路中常用的1×240-4×630mm。规格下各种节能导线的载流量、电能损耗等电气特性和弧垂、风偏、过载能力、荷载等机械特性以及建设投资经济性，然后结合某500kV线路工程计算了4×630mm2截面规格下各节能导线的年费用。最后，综合考虑实际工程的具体特点给出了110～500kV电压等级下不同规格节能导线的选型建议。
In this paper,the characteristics of various energy-saving conductor was introduced. The electrical characteristics and mechanical properties as well as construction investment economy of various energy--saving conductor with cross section 1×240mm2- 4×630 mm2 specifications, such as ampacity, energy loss, sag, swing angle, overload ice thickness ,load and were analyzed, which were commonly used in 110 kV-500 kV transmission line .Then the annual cost of various of energy saving conductor with 4 ×630 mm2 cross section ＂specifications was calculated based on a certain 500 kV transmission line project. Finally, considering the different characteristics of the actual project gives 110 kV-500 kV voltage levels under different specifications of the energy conductor selection recommendations.
