铝包钢线是一种将铝连续均匀包覆在钢芯上的双金属线，它兼有导电性能好，耐腐蚀，高频传输性能好以及钢的强度高等优点。铝包钢芯铝绞线是将铝包钢线作加强芯和铝线绞合在一起的绞线，与普通钢芯铝绞线相比，导体重量轻5%，载流量2－3%；电力损耗减少4－6%；使用寿命长，而且不增加任何架设费用。它广泛适用于输电线路用导线，尤其是沿海地区，盐碱滩和三、四级污染工业区的输电线路和要求铝钢截面比的输配电线路用导线。
铝包钢绞线按导电率分为：20AC、23AC、27AC、30AC、33AC、40AC六个组别，其相应的导电率为20.3%、23%、27%、30%、33%和40%IACS.
铝包钢绞线的代号为：LBGJ
产品执行标准（Production Executive Standard）：GB/T 1179-2008 IEC610898-1991
