公司主打漆包線型號有(you)（155，180級(ji)）聚氨酯（QA/UEW）、(130，155級(ji))聚酯（QZ/PEW）等及各類自(zi)粘性銅包鋁漆包線。

銅包鋁線(xian)(xian)是一種新型的(de)導線(xian)(xian)材(cai)料，主要用(yong)(yong)來取(qu)代全系(xi)列(lie)純(chun)鋁合(he)金線(xian)(xian)和(he)電(dian)纜。它(ta)的(de)導電(dian)性能(neng)優良(liang)且成本相對較低(di)(di)，適合(he)用(yong)(yong)于各種連(lian)接線(xian)(xian)路和(he)電(dian)力輸送等重要場(chang)合(he).在一些(xie)特殊情況下(xia)（如、臺風），或受損(sun)但(dan)未(wei)斷(duan)開的(de)電(dian)線(xian)(xian)可能(neng)會造成觸(chu)點短路或者因接觸(chu)不良(liang)導致電(dian)阻過大產生高溫燒毀等問題發生時它(ta)可以(yi)起到(dao)保護電(dian)路板安(an)全的(de)作(zuo)(zuo)用(yong)(yong)；同時它(ta)還(huan)可以(yi)降低(di)(di)布線(xian)(xian)的(de)安(an)裝(zhuang)難度從而(er)提高整個系(xi)統的(de)穩定性和(he)工作(zuo)(zuo)效率。（注意：當外界溫度過低(di)(di)或缺(que)水(shui)的(de)時候(hou)不建議使用(yong)(yong)。）

銅包鋁和純銅進行以下(xia)四方面(mian)的比(bi)較：

機械特性：

純(chun)(chun)(chun)銅(tong)(tong)導(dao)(dao)體(ti)(ti)強度(du)、伸長率比(bi)(bi)(bi)銅(tong)(tong)包鋁導(dao)(dao)體(ti)(ti)大，也就是(shi)說純(chun)(chun)(chun)銅(tong)(tong)在(zai)機械性(xing)能(neng)方面比(bi)(bi)(bi)銅(tong)(tong)包鋁好。從電(dian)(dian)纜設計的角度(du)來(lai)看，純(chun)(chun)(chun)銅(tong)(tong)導(dao)(dao)體(ti)(ti)比(bi)(bi)(bi)銅(tong)(tong)包鋁導(dao)(dao)體(ti)(ti)機械強度(du)好的優點(dian)，在(zai)實際應用過程中不一定(ding)需(xu)要。銅(tong)(tong)包鋁導(dao)(dao)體(ti)(ti)比(bi)(bi)(bi)純(chun)(chun)(chun)銅(tong)(tong)輕很多，因此銅(tong)(tong)包鋁的電(dian)(dian)纜在(zai)整(zheng)體(ti)(ti)重量上比(bi)(bi)(bi)純(chun)(chun)(chun)銅(tong)(tong)導(dao)(dao)體(ti)(ti)電(dian)(dian)纜要輕，這(zhe)樣(yang)會(hui)給(gei)電(dian)(dian)纜的運輸和電(dian)(dian)纜的架(jia)設施工帶來(lai)方便。另外(wai)銅(tong)(tong)包鋁比(bi)(bi)(bi)純(chun)(chun)(chun)銅(tong)(tong)軟(ruan)一點(dian)，用銅(tong)(tong)包鋁導(dao)(dao)體(ti)(ti)生產的電(dian)(dian)纜在(zai)柔軟(ruan)性(xing)方面比(bi)(bi)(bi)純(chun)(chun)(chun)銅(tong)(tong)的電(dian)(dian)纜好一點(dian)。

電氣性能：

因為鋁的導(dao)電性(xing)比銅(tong)(tong)差，使得銅(tong)(tong)包(bao)鋁導(dao)體的直流電阻比純銅(tong)(tong)導(dao)體大，這(zhe)點有(you)無影響主要(yao) 2014年中(zhong)考沖刺綜合復習(xi)指導(dao)北京(jing)地(di)區試(shi)(shi)提(ti) 廣東地(di)區試(shi)(shi)提(ti)
