中强度全铝合金导线是一种由中强度铝合金单线绞制而成的铝合金绞线。在架空输电线路上采用中强度全铝合金导线较目前普遍采用的钢芯铝绞线具有以下优点：(1)导线拉重比大，弧垂特性好，可增大输电杆塔档距，降低线路建设投资。(2)导线高温特性好，在更高温度下运行，强度损失少。(3)导线表面耐损伤。中强度铝合金的硬度为铝线的2倍，但重量比钢芯铝绞线轻，施工放线时可减少导线表画擦伤，提高施工质量。高表面质量的导线可减少运行时电晕损失及无线电干扰水平。(4)由于没有钢芯，因此没有磁滞损失和涡流损失，在运行时，其交流电阻比钢芯铝绞线低，故电能损失减少。正由于这些优点，中强度全铝合金绞线在输电线路上使用越来越多。
下面结合附图和具体实施例对本发明作详细的描述。
