摘　　要：为了降低输电线路的电阻损耗,提高传输效率,达到节能的效果。介绍了钢芯高导电率铝绞线,铝合金芯高导电率铝绞线,中强度铝合金绞线3类节能导线的特点及节能原理,并通过测量直流电阻,对具体线路分别从电阻损耗,环境效益,线路投资方面进行分析,比较其节能效果。结果表明中强度铝合金绞线节能效果最好,每千米约节约电量8.2%,且在3年内即可收回设备投资,具有重要的推广价值,可为今后替代普通钢芯铝绞线在节能导线的选型上提供参考。In order to reduce the resistance loss,improve the efficiency of the transmission line and reach energysaving effect. This article describes the energy conservation principle and characteristics of energy-saving efforts of the wire and marketed high conductivity steel-cored aluminum strand,aluminum alloy-cored aluminum stranded wire and medium intensity aluminum stranded wire. By measuring the DC resistance analyzing the concrete lines from resistive losses,environmental benefits and investment of line and comparing the energy-saving effect of three energy-saving wires. The results show that the energy-saving effect of medium intensity aluminum stranded wire is the best. Per kilometer saves electricity about 8. 2% and it can recover the investment of equipment in three years.It has an important promotion value and may provide the reference for the future instead of common steel core aluminum stranded wire in the choice of the energy-saving wire.
