铝包钢绞线
我公司有五十余年的电线电缆生产历史,专业生产制造铝包钢系列产品。
铝包钢绞线定义:
是由一定根数的铝包钢单丝绞制而成;铝包钢单丝是一种将铝连续均匀包覆在钢芯上的双金属丝,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。
用 途:
用于大跨越输电线,良导体避雷地线,光纤复合架空地线,电线架设绞线,防冰雪导线,倍容导线,自阻尼导线,电气化铁路接触网承力索。
执行标准:
GB/T 1179-2008、YB/T 124-1997,TB/T2938,ASTM B 416,AS 1222, IEC610898-1991
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、JLB1A、JLB1
