“惠农-宝丰110千伏线路工程”为宁夏电力公司节能导线试点工程,线路全长12.8km,共架设47基铁塔。工程采用JLHA3-335中强度铝合金绞线。目前,国内架空导线一般采用钢芯铝绞线,导电率为53%IACS(国际退火铜标准)。随着全国电力的发展,输电能力的要求不断提高,此次宁夏首条节能导线采用中强度全铝合金绞线。中强度全铝合金导线导电率为58.5%,比一般钢芯铝绞线高出5.5%,具有传输容量大、拉重比大、电阻损耗低、弧垂性能 “Huinong - Baofeng 110 kV line project” for the pilot project of Ningxia Electric Power Company energy-saving wire, the line length of 12.8km, a total of 47 base tower erected. The project uses JLHA3-335 medium strength aluminum alloy wire. At present, the domestic overhead conductors are generally ACSR, the electrical conductivity of 53% IACS (International Annealed Copper Standard). With the development of national power transmission capacity requirements continue to increase, the first energy-saving wire in Ningxia with all-aluminum alloy strands. Medium-strength all-aluminum alloy wire conductivity of 58.5%, 5.5% higher than the average ACSR, with transmission capacity, pull heavy ratio, low resistance loss, arc sag
