銅(tong)(tong)包(bao)鋁(lv)導(dao)體是(shi)(shi)(shi)按重量(liang)出售的(de)(de)(de)，純銅(tong)(tong)導(dao)體也是(shi)(shi)(shi)按重量(liang)出售的(de)(de)(de)，銅(tong)(tong)包(bao)鋁(lv)導(dao)體的(de)(de)(de)價(jia)格(ge)要比(bi)相(xiang)同(tong)重量(liang)的(de)(de)(de)純銅(tong)(tong)導(dao)體貴一些。但是(shi)(shi)(shi)同(tong)樣(yang)重量(liang)的(de)(de)(de)銅(tong)(tong)包(bao)鋁(lv)要比(bi)純銅(tong)(tong)導(dao)體長(chang)度長(chang)很多(duo)，而電(dian)纜(lan)是(shi)(shi)(shi)按長(chang)度計算的(de)(de)(de)。相(xiang)同(tong)重量(liang)銅(tong)(tong)包(bao)鋁(lv)線(xian)是(shi)(shi)(shi)銅(tong)(tong)線(xian)長(chang)度的(de)(de)(de)2.5倍(bei)，價(jia)格(ge)僅(jin)僅(jin)是(shi)(shi)(shi)每噸多(duo)幾百元。綜(zong)合下來(lai)，銅(tong)(tong)包(bao)鋁(lv)就(jiu)很有(you)優勢。由(you)于(yu)銅(tong)(tong)包(bao)鋁(lv)電(dian)纜(lan)比(bi)較輕(qing)，電(dian)纜(lan)的(de)(de)(de)運輸成(cheng)本、安裝架設成(cheng)本都會(hui)有(you)所降低，會(hui)給施(shi)工帶來(lai)一定的(de)(de)(de)方便性。

公司主(zhu)打漆(qi)包線(xian)型號有（155，180級(ji)）聚氨酯(zhi)（QA/UEW）、(130，155級(ji))聚酯(zhi)（QZ/PEW）等(deng)及各類自粘性銅包鋁漆(qi)包線(xian)。

銅包鋁線(xian)是一種(zhong)(zhong)(zhong)將銅和鋁兩種(zhong)(zhong)(zhong)金(jin)屬結合在一起的線(xian)材，具有以(yi)下幾種(zhong)(zhong)(zhong)作(zuo)用：

提(ti)高導(dao)電(dian)性能：銅包鋁(lv)線(xian)的(de)導(dao)電(dian)性能優(you)于純鋁(lv)線(xian)，因(yin)此可以用于替代(dai)純鋁(lv)線(xian)，提(ti)高電(dian)氣設備的(de)導(dao)電(dian)性能。

減(jian)小(xiao)電(dian)(dian)阻(zu)(zu)(zu)：銅(tong)包(bao)鋁(lv)(lv)線的(de)電(dian)(dian)阻(zu)(zu)(zu)比純(chun)鋁(lv)(lv)線小(xiao)，因此可以用于替代(dai)純(chun)鋁(lv)(lv)線，減(jian)小(xiao)電(dian)(dian)氣設備的(de)電(dian)(dian)阻(zu)(zu)(zu)，提(ti)高電(dian)(dian)能的(de)傳輸(shu)效(xiao)率。

提高耐(nai)腐蝕(shi)性能：銅包鋁(lv)線的(de)耐(nai)腐蝕(shi)性能優于(yu)純鋁(lv)線，因(yin)此(ci)可以用于(yu)替代純鋁(lv)線，提高電氣設備的(de)耐(nai)腐蝕(shi)性能。

降低成(cheng)本：銅(tong)包(bao)(bao)鋁線(xian)的成(cheng)本比純銅(tong)線(xian)低，鋁漆包(bao)(bao)線(xian)價格，因此可以(yi)用于(yu)替代純銅(tong)線(xian)，降低電(dian)氣設備的成(cheng)本。

需要注意的(de)(de)是，銅(tong)包(bao)鋁線的(de)(de)性能受(shou)到銅(tong)和鋁兩種金屬的(de)(de)比例、加工(gong)(gong)工(gong)(gong)藝(yi)(yi)等因(yin)(yin)素的(de)(de)影(ying)響，因(yin)(yin)此在(zai)使用(yong)時應該(gai)根據具體(ti)情況選擇合適的(de)(de)材料和加工(gong)(gong)工(gong)(gong)藝(yi)(yi)。此外，在(zai)使用(yong)時應該(gai)注意安全，例如佩戴防護裝備、避免接觸有毒物質(zhi)等。
