摘　　要：结合国家电网公司基建新技术的推广应用,介绍了高导电率钢芯铝绞线、铝合金芯铝绞线和中强度全铝合金绞线的节能原理和性能,对比分析了3种新型节能导线在电气、机械特性等方面的技术差异,并对影响线路造价的敏感因素进行了分析,采用年费用和投资回收期法对导线的经济性进行了评价,最后提出了3种新型节能导线的工程应用范围,为节能导线的推广应用提供了参考。Combined with the polarization and application of new technologies in capital construction, the energy-saving principle and performance of the high conductivity aluminum conductor steel reinforced（ ACSR）, aluminum conductor alloy reinforced （ACAR） and moderate-strength all aluminum alloy conductor （AAAC） are introduced. Subsequently, the technical differences in electrical and mechanical properties between the three conductors are comparative analyzed, and the sensitive factors of construction cost are also discussed. By the means of both annual cost and payback methods, the economy evaluations of the three conductors are made. In order to popularize the energy-saving conductors, some application suggestions are proposed in the end.
