铝包钢芯铝绞线是由铝包钢丝做加强芯和硬铝线绞合组成的架空导线。铝包钢芯铝绞线和普通钢芯铝绞线相比，绞线重量轻5%，载流量提高2～3%，弧垂减小1～2%，电力损耗减少4～6%，且防腐性能好、使用寿命长、结构简单、架设和维护方便、传输容量大。它广泛适用于各种电压等级的输电线路和要求增大铝钢截面比的输电线路，还可用于沿海地区、盐碱滩和三、四级工业污染区输电线路。

规格范围：15/3mm2～1225/100mm2

型号：JL/LB1A

产品性能

1铝包钢芯铝绞线的电性能包括铝包钢线中铝包层的电导，以其20℃时的千米直流电阻表示。绞线所用硬铝线的电阻率为28.264 nΩ·m。

2铝包钢芯铝绞线的额定抗拉力以组成铝包钢芯铝绞线的铝部抗拉力与铝包钢部抗拉力之和表示。

执行标准：GB/T 1179-2008《圆线同心绞架空导线》
