銅(tong)包鋁和純銅(tong)進(jin)行以下四方(fang)面的比較(jiao)：

機械特性：

純(chun)(chun)銅(tong)(tong)導(dao)體(ti)(ti)(ti)強(qiang)度、伸長(chang)率比(bi)(bi)(bi)銅(tong)(tong)包(bao)(bao)鋁(lv)導(dao)體(ti)(ti)(ti)大，也就是說純(chun)(chun)銅(tong)(tong)在機械(xie)性能方面(mian)比(bi)(bi)(bi)銅(tong)(tong)包(bao)(bao)鋁(lv)好。從電(dian)纜(lan)設(she)計的(de)角度來(lai)(lai)看，純(chun)(chun)銅(tong)(tong)導(dao)體(ti)(ti)(ti)比(bi)(bi)(bi)銅(tong)(tong)包(bao)(bao)鋁(lv)導(dao)體(ti)(ti)(ti)機械(xie)強(qiang)度好的(de)優點，在實際應(ying)用過(guo)程中不(bu)一定需要(yao)。銅(tong)(tong)包(bao)(bao)鋁(lv)導(dao)體(ti)(ti)(ti)比(bi)(bi)(bi)純(chun)(chun)銅(tong)(tong)輕很(hen)多(duo)，因此銅(tong)(tong)包(bao)(bao)鋁(lv)的(de)電(dian)纜(lan)在整體(ti)(ti)(ti)重量上比(bi)(bi)(bi)純(chun)(chun)銅(tong)(tong)導(dao)體(ti)(ti)(ti)電(dian)纜(lan)要(yao)輕，這(zhe)樣會給電(dian)纜(lan)的(de)運輸和(he)電(dian)纜(lan)的(de)架設(she)施工(gong)帶來(lai)(lai)方便。另外銅(tong)(tong)包(bao)(bao)鋁(lv)比(bi)(bi)(bi)純(chun)(chun)銅(tong)(tong)軟(ruan)一點，用銅(tong)(tong)包(bao)(bao)鋁(lv)導(dao)體(ti)(ti)(ti)生產(chan)的(de)電(dian)纜(lan)在柔(rou)軟(ruan)性方面(mian)比(bi)(bi)(bi)純(chun)(chun)銅(tong)(tong)的(de)電(dian)纜(lan)好一點。

電氣性能：

因為鋁的導(dao)電性比(bi)銅(tong)差(cha)，使得銅(tong)包(bao)鋁導(dao)體的直(zhi)流電阻比(bi)純(chun)銅(tong)導(dao)體大，這(zhe)點有(you)無影響主(zhu)要 2014年中考沖刺(ci)綜合復習指導(dao)北京地(di)區試提 廣(guang)東地(di)區試提

漆包線小編談(tan)談(tan)實戰(zhan)操(cao)作感想和認知

漆包線(xian)(xian)小編：在一臺(tai)正常運(yun)轉(zhuan)的(de)漆包機上，操(cao)作人員的(de)精力和(he)膂力大(da)多數(shu)耗費在放(fang)線(xian)(xian)有些，互換放(fang)線(xian)(xian)盤使操(cao)作者支付很大(da)的(de)勞動力，銅包鋁電線(xian)(xian)，換線(xian)(xian)時(shi)接頭易發作質量疑問(wen)及(ji)發作運(yun)轉(zhuan)毛病。有用的(de)辦法是大(da)容量放(fang)線(xian)(xian)。

放(fang)(fang)線(xian)(xian)的(de)關鍵是操控張(zhang)力(li)(li)，常州銅(tong)包(bao)鋁，張(zhang)力(li)(li)大時不只拉細導體，使(shi)導線(xian)(xian)外表(biao)失掉亮(liang)光(guang)(guang)，還影(ying)響漆包(bao)線(xian)(xian)的(de)多項功能(neng)。從外表(biao)上看(kan)，被(bei)拉細的(de)導線(xian)(xian)，銅(tong)包(bao)鋁電纜，涂(tu)制(zhi)出的(de)漆包(bao)線(xian)(xian)光(guang)(guang)澤較差；從功能(neng)來(lai)看(kan)，漆包(bao)線(xian)(xian)伸長(chang)率(lv)、回彈性(xing)、柔(rou)韌性(xing)、熱沖擊都受到(dao)影(ying)響。放(fang)(fang)線(xian)(xian)張(zhang)力(li)(li)太小(xiao)，線(xian)(xian)容易跳動形成(cheng)(cheng)并線(xian)(xian)、線(xian)(xian)碰爐(lu)口(kou)。放(fang)(fang)線(xian)(xian)時怕半圈張(zhang)力(li)(li)大，半圈張(zhang)力(li)(li)小(xiao)，這樣不只使(shi)導線(xian)(xian)松亂、扎斷，一段一段被(bei)拉細，而且還會(hui)導致烘(hong)爐(lu)內(nei)線(xian)(xian)的(de)大跳動，形成(cheng)(cheng)并線(xian)(xian)、碰線(xian)(xian)毛病。放(fang)(fang)線(xian)(xian)張(zhang)力(li)(li)要(yao)均(jun)勻恰當。
