铝包钢芯耐热铝合金导线是以铝包钢芯作为加强芯,以耐热铝合金作为载流体的复合导线,是一种新型的节能导线。加强芯由铝包钢芯代替了传统的钢芯,减小了其化学腐蚀,增加了其使用寿命;外层采用耐热铝合金材料,工作温度不仅达到 150℃以上,其导电率提高到60%IACS,大大提高了导线的运载能力。
与传统的钢芯铝绞线相比,铝包钢芯耐热铝合金导线具有使用温度高、耐热性能好、载流量大、耐腐蚀性能好、蠕变性能好等等优点。耐热铝合金导线最大的特点就是允许工作温度高,与同截面的钢芯铝绞线相比,载流量能提高50%以上,在线路扩容改造过程中,尤其在线路走廊狭窄地区,只需要更换相近截面规格的耐热铝合金导线,不需要更换铁塔就能达到增大送电容量的目的。这非常适用于受用地限制,或更新线路需要花费更多的人力、财力的地方。
