銅包鋁電線電纜適應時代的發展得到廣泛應用，和湖北安耀紅旗電纜股份有限公司的小編了解。

額定(ding)電(dian)(dian)(dian)壓(ya)450/750V及以(yi)下(xia)(xia)聚氯(lv)乙烯絕緣(yuan)電(dian)(dian)(dian)纜(lan)和30KV及以(yi)下(xia)(xia)電(dian)(dian)(dian)力電(dian)(dian)(dian)纜(lan)，適用(yong)于交(jiao)流(liu)額定(ding)電(dian)(dian)(dian)壓(ya)450/750V及以(yi)下(xia)(xia)的(de)(de)照明、電(dian)(dian)(dian)器動(dong)力裝置固定(ding)敷設和30KV以(yi)下(xia)(xia)電(dian)(dian)(dian)力輸(shu)配(pei)電(dian)(dian)(dian)系統中，供輸(shu)配(pei)電(dian)(dian)(dian)能之用(yong)。廣泛(fan)應用(yong)于電(dian)(dian)(dian)力、建筑、工(gong)礦、冶金、石油化(hua)工(gong)、交(jiao)通等部門。其特征為具(ju)有(you)良好的(de)(de)耐腐(fu)蝕性，導(dao)(dao)體(ti)(ti)接觸電(dian)(dian)(dian)阻小；具(ju)有(you)良好的(de)(de)焊接性，銅(tong)(tong)包(bao)鋁線由于其表面(mian)包(bao)覆(fu)了(le)(le)一層純(chun)銅(tong)(tong)，因此具(ju)有(you)跟純(chun)銅(tong)(tong)線一樣(yang)的(de)(de)可焊接性；重量(liang)輕、線質柔軟、易于加(jia)工(gong)、便于安裝、運輸(shu)；銅(tong)(tong)包(bao)鋁材料具(ju)有(you)相(xiang)對(dui)成本(ben)低(di)、價(jia)格相(xiang)對(dui)穩(wen)定(ding)的(de)(de)優(you)點，克服了(le)(le)銅(tong)(tong)材成本(ben)高，價(jia)格大(da)起(qi)大(da)落的(de)(de)弊端；與純(chun)銅(tong)(tong)導(dao)(dao)體(ti)(ti)相(xiang)比，除具(ju)備銅(tong)(tong)導(dao)(dao)體(ti)(ti)的(de)(de)優(you)點外，在導(dao)(dao)體(ti)(ti)直(zhi)流(liu)電(dian)(dian)(dian)阻與純(chun)銅(tong)(tong)導(dao)(dao)體(ti)(ti)直(zhi)流(liu)電(dian)(dian)(dian)阻相(xiang)同的(de)(de)條件下(xia)(xia)，它(ta)的(de)(de)交(jiao)流(liu)電(dian)(dian)(dian)阻比銅(tong)(tong)下(xia)(xia)，載流(liu)量(liang)比銅(tong)(tong)導(dao)(dao)體(ti)(ti)大(da)2%-5%(截面(mian)積越大(da)效果越明顯)。
