銅(tong)包(bao)(bao)鋁線(xian)是在鋁芯上同心地包(bao)(bao)覆銅(tong)層并使銅(tong)鋁界面形成金屬結合的雙金屬復合導線(xian)，它是銅(tong)導線(xian)的更新換代產品，二十(shi)一世紀的新復合材(cai)料。具有合理利用自(zi)然(ran)資源，銅(tong)包(bao)(bao)鋁，降低生產成本，方(fang)便工程施工等(deng)優點，具有廣闊的發展前景。

1、 銅包鋁線的(de)規格(ge)及表(biao)示(shi)方法(fa)

銅(tong)(tong)(tong)包(bao)鋁(lv)線按銅(tong)(tong)(tong)層體(ti)積(ji)比(bi)(bi)（銅(tong)(tong)(tong)層體(ti)積(ji)占銅(tong)(tong)(tong)包(bao)鋁(lv)線的體(ti)積(ji)百分(fen)比(bi)(bi)）不(bu)同分(fen)為(wei)(wei)(wei)兩(liang)種：銅(tong)(tong)(tong)層體(ti)積(ji)比(bi)(bi)在(zai)8-12%范圍內(nei)的為(wei)(wei)(wei)10%級(ji)（簡記為(wei)(wei)(wei)10），銅(tong)(tong)(tong)層體(ti)積(ji)比(bi)(bi)在(zai)13-17%范圍內(nei)的為(wei)(wei)(wei)15%級(ji)（簡記為(wei)(wei)(wei)15）。銅(tong)(tong)(tong)包(bao)鋁(lv)線按軟硬(ying)狀態不(bu)同又分(fen)為(wei)(wei)(wei)兩(liang)種：拉(la)拔(ba)后未退火者為(wei)(wei)(wei)硬(ying)態以H表示。拉(la)拔(ba)后退火者為(wei)(wei)(wei)軟態以A表示。因此銅(tong)(tong)(tong)包(bao)鋁(lv)線可分(fen)為(wei)(wei)(wei)四類(lei)：10H

、10A、15H、15A。各類銅包鋁(lv)線又(you)可拉拔成不同的標稱直徑。銅包鋁(lv)線以代號CCA（Copper Clad

Aluminum)表示(shi)，其規(gui)格表示(shi)方法為：例如：對于(yu)直徑2.77mm，銅層體積比為15%的(de)軟態銅包鋁線，其規(gui)格的(de)標記(ji)為：CCA-15A-2.77

公(gong)司主打(da)漆包線型號有（155，180級）聚氨酯(zhi)(zhi)（QA/UEW）、(130，155級)聚酯(zhi)(zhi)（QZ/PEW）等及(ji)各類自粘性銅包鋁漆包線。

銅包鋁(lv)(lv)線(xian)(xian)(xian)是一種(zhong)新型的(de)(de)導(dao)線(xian)(xian)(xian)材料，主要(yao)用來取代(dai)全(quan)(quan)系(xi)列純鋁(lv)(lv)合金線(xian)(xian)(xian)和電(dian)(dian)纜。它的(de)(de)導(dao)電(dian)(dian)性能優良且成(cheng)本相對較低，適(shi)合用于各種(zhong)連接(jie)線(xian)(xian)(xian)路和電(dian)(dian)力輸送等重要(yao)場(chang)合.在(zai)一些特(te)殊情(qing)況(kuang)下(xia)（如、臺風(feng)），銅包鋁(lv)(lv)電(dian)(dian)線(xian)(xian)(xian)，或受損但未斷開(kai)的(de)(de)電(dian)(dian)線(xian)(xian)(xian)可能會(hui)造成(cheng)觸(chu)點(dian)短路或者因接(jie)觸(chu)不良導(dao)致電(dian)(dian)阻過大產生(sheng)高溫(wen)燒毀等問(wen)題發生(sheng)時(shi)(shi)它可以起到保(bao)護電(dian)(dian)路板安全(quan)(quan)的(de)(de)作用；同時(shi)(shi)它還可以降(jiang)低布線(xian)(xian)(xian)的(de)(de)安裝難度從而提高整個系(xi)統的(de)(de)穩定性和工(gong)作效(xiao)率。（注意：當外界溫(wen)度過低或缺水(shui)的(de)(de)時(shi)(shi)候不建議使用。）
