节能导线在架空输电线路工程中选型应用分析

Analysis on Selecting Application of Energy-Saving Conductors in Overhead Transmission Line Construction

与等外径的普通钢芯铝绞线相比,节能导线的直流电阻小,可提高导线导电能力,减少输电线路损耗,达到节能效果。分析了节能导线与普通钢芯铝绞线的电气特性、机械特性、施工安装、线路造价分析以及线路年费用等情况,提出了工程中节能导线选型的通用方法。

Comparing with common aluminium conductor steel reinforced (ACSR) with equal outside di-ameter, the DC resistance of energy-saving conductor is lower, so applying it in transmission lines can enhance conductivity and decrease line losses. This paper introduces electrical characteristics, mechanical characteristics, construction installation, line’s cost analysis as well as annual cost, and other conditions of the energy-saving conductor and common aluminium conductor steel reinforced. A general method of selecting energy-saving conductors is proposed binding with the project.
