铝包钢线具备钢线的优越抗拉性能和铝的良好导电性能，耐腐蚀性能大大优于镀锌钢线，耐热性能良好。采用20.3％IACS的铝包钢线代替镀锌钢线作为加强芯，与高导电率铝线组成节能导线，比同规格的钢芯高导电率铝绞线机械性能有所提高，弧垂特性稍好，耐腐蚀性能明显提高，而电晕特性、电磁环境特性保持不变；尤其适用于沿海和重污秽地区，能够延长导线的使用寿命；应用于钢比为7％、9％、13％的导线时使电阻率分别下降1.2％、1.6％、2.3％以上。在500 kV线路典型算例中，导线费用增加部分约4年即可从降低的电能损耗中收回，此后每年能有很大的经济效益，值得推广。

Aluminum-clad steel wire has the advantages of the good tensile strength of steel and the good conductivity of aluminum,and has much better anti-corrosion performance than zinc-coated steel wire,as well as the good thermal resistance.By replacing zinc-coated steel wire with 20.3% IACS aluminum-clad steel wire,and using high conductivity aluminum conductors,the composite energy-saving conductor has better mechanical performance,better sag characteristics, and better anti-corrosion performance than the zinc-coated steel reinforced cable, while keeps the same corona and electromagnetic environment characteristics.It is especially suitable for coastal or heavy polluted area.With using ACSR of 7%,9%,13% steel ratio,the resistivity of cable is reduced by 1.2%,1.6%,2.3%,respectively.Taking 500 kV transmission line as typical example,the saved energy loss can cover the extra conductor cost in 4 years,and give good financial benefit in following years.The aluminum-clad steel reinforced cable is worth popularizing.
