產品詳情
河南鄭州JNRLH58/LB1A-鋁包鋼芯耐熱鋁合金絞線生產廠家 鋁包鋼芯耐熱鋁合金導線是以鋁包鋼芯作為加強芯，以耐熱鋁合金作為載流體的復合導線，是一種新型的節能導線。加強芯由鋁包鋼芯代替了傳統的鋼芯，減小了其化學腐蝕，增加了其使用壽命;外層采用耐熱鋁合金材料，工作溫度不僅達到 150℃以上，其導電率提高到60%IACS，大大提高了導線的運載能力。
與傳統的鋼芯鋁絞線相比，鋁包鋼芯耐熱鋁合金導線具有
使用溫度高、耐熱性能好、載流量大、耐腐蝕性能好、蠕變性能好等等優點。耐熱鋁合金導線最大的特點就是允許工作溫度高，與同截面的鋼芯鋁絞線相比，載流量能提高50%以上，在線路擴容改造過程中，尤其在線路走廊狹窄地區，只需要更換相近截面規格的耐熱鋁合金導線，不需要更換鐵塔就能達到增大送電容量的目的。這非常適用于受用地限制，或更新線路需要花費更多的人力、財力的地方。
