鋁包鋼線(xiàn)是一種將鋁連續(xù)均勻包覆在鋼芯上的雙金屬線(xiàn),它兼有導(dǎo)電性能好,耐腐蝕,高頻傳輸性能好以及鋼的強(qiáng)度高等優(yōu)點(diǎn)。鋁包鋼芯鋁絞線(xiàn)是將鋁包鋼線(xiàn)作加強(qiáng)芯和鋁線(xiàn)絞合在一起的絞線(xiàn),與普通鋼芯鋁絞線(xiàn)相比,導(dǎo)體重量輕5%,載流量提高2-3%;電力損耗減少4-6%;
使用壽命長(zhǎng),而且不增加任何架設(shè)費(fèi)用。它廣泛適用于輸電線(xiàn)路用導(dǎo)線(xiàn),尤其是沿海地區(qū),鹽堿灘和三、四級(jí)污染工業(yè)區(qū)的輸電線(xiàn)路和要求增大鋁鋼截面比的輸配電線(xiàn)路用導(dǎo)線(xiàn)。
鋁包鋼絞線(xiàn)按導(dǎo)電率分為:20AC、23AC、27AC、30AC、33AC、40AC六個(gè)組別,其相應(yīng)的導(dǎo)電率為20.3%、23%、27%、30%、33%和40%IACS.
鋁包鋼絞線(xiàn)的代號(hào)為:LBGJ
