摘要 铝包钢线具有优良的机械、电气和防腐性能。与传统钢芯铝绞线相比,用铝包钢线代替镀锌钢线的铝包钢芯铝绞线具有重量轻、电阻小、耐腐蚀、弧垂小的特点,尤其适合在沿海及重污秽地区应用;采用20.3%IACS的LB20铝包钢芯代替镀锌钢芯与高导电率铝线组成的节能导线即铝包钢芯高导铝绞线,可充分利用现有生产技术,叠加发挥两种材料的节能效果,与同规格的钢芯高导电率铝绞线相比,交流电阻进一步降低约1.6%-2.7%。500 k V线路典型算例表明:综合考虑导线价格成本和节能效益,JL3/LB20和JL2/LB20型铝包钢芯高导铝绞线具有较高的经济效益,值得推广。 Aluminum-clad steel wire has excellent performance of mechanical, electrical and anti-corrosion. By replacing Zinc-coated steel with aluminum-clad steel wire, aluminum-cad steel core aluminum stranded wire has lighter weight, smaller resistance, better anti-corrosion performance and better sag characteristics, compared to the traditional ACSR, especially suitable for coastal and heavy polluted area. Composed of 20.3% IACS aluminum-clad steel wire and high conductivity aluminum conductor, the new energy-saving conductor i. e. high conductivity aluminum conductor aluminum-clad steel reinforced cable can superpose two materials' energy-saving effect, and further reduce AC resistance about 1.6 % -2.7 % compared with the same specifications of the Zinc-coated steel core high conductivity aluminum cable. A typical example of 500 kV transmission line shows, JL3/LB20 and JL2/LB20 type of the new energy-saving conductor has a notable energy conservation economic effect and worth promoting.
