一、漆包銅線和漆包鋁線怎么區分

漆包(bao)(bao)線(xian)(xian)(xian)按照材質不(bu)同(tong)有銅線(xian)(xian)(xian)、鋁(lv)(lv)(lv)線(xian)(xian)(xian)、銅包(bao)(bao)鋁(lv)(lv)(lv)線(xian)(xian)(xian)等多種，其中比(bi)較常用的是(shi)銅線(xian)(xian)(xian)和鋁(lv)(lv)(lv)線(xian)(xian)(xian)，漆包(bao)(bao)銅線(xian)(xian)(xian)和漆包(bao)(bao)鋁(lv)(lv)(lv)線(xian)(xian)(xian)性(xing)能(neng)有所不(bu)同(tong)，那么怎么區(qu)分漆包(bao)(bao)銅線(xian)(xian)(xian)和鋁(lv)(lv)(lv)線(xian)(xian)(xian)呢(ni)？

取一小段漆(qi)(qi)(qi)包(bao)(bao)線(xian)，用打火機直接燒(shao)線(xian)頭(tou)，當燒(shao)出的線(xian)頭(tou)變成(cheng)灰(hui)或(huo)(huo)灰(hui)色渣狀時，此線(xian)為鋁(lv)漆(qi)(qi)(qi)包(bao)(bao)線(xian)或(huo)(huo)銅(tong)包(bao)(bao)鋁(lv)漆(qi)(qi)(qi)包(bao)(bao)線(xian)；當燒(shao)出的線(xian)頭(tou)變成(cheng)球(qiu)狀或(huo)(huo)只燒(shao)去漆(qi)(qi)(qi)層而露出紅(hong)色金屬線(xian)狀，此線(xian)為銅(tong)漆(qi)(qi)(qi)包(bao)(bao)線(xian)。

二、漆包銅線和漆包鋁線哪個好

漆包線(xian)銅(tong)線(xian)和鋁線(xian)相(xiang)比，各(ge)有(you)各(ge)的好(hao)處：銅(tong)比鋁的導(dao)電(dian)性要好(hao)、抗拉強度高、耐溫高，而缺點是銅(tong)的成本高、比鋁重(zhong)。不過整體來說，還是漆包銅(tong)線(xian)要好(hao)一些。

除了(le)銅線和鋁線的截流量和材質不同(tong)以外(wai)，由于漆包鋁線質量更輕，機械(xie)強度較差，在接(jie)(jie)駁(bo)線端(duan)極容易氧化(hua)(hua)，接(jie)(jie)駁(bo)線端(duan)氧化(hua)(hua)后會出現溫度升高、接(jie)(jie)觸不良等情況，是引起故障（斷(duan)電或斷(duan)線）的多發點。因(yin)此，一些比較重(zhong)要的領(ling)域都用的是漆包銅線。

三、鋁漆包線改銅漆包線怎樣換算

漆包鋁線和漆包銅線的材質不同，改的時候要注意換算大小，具體的換算公式為：

D銅＝(ρ銅/ρ鋁)/2*D鋁

D銅(tong)：銅(tong)線(xian)直徑；D鋁：鋁線(xian)直徑；ρ鋁：鋁的電阻(zu)率(lv)，取1/35.5；ρ銅(tong)：銅(tong)的電阻(zu)率(lv)，取1/58。

比如，使用1.18㎜的鋁漆(qi)包(bao)線(xian)(xian)，改為使用銅(tong)(tong)線(xian)(xian)時，銅(tong)(tong)線(xian)(xian)的線(xian)(xian)徑為D銅(tong)(tong)=(35.5/58)1/2*1.18=0.61211/2*1.18=0.7823*1.18=0.92，即1.18㎜鋁漆(qi)包(bao)線(xian)(xian)改為銅(tong)(tong)漆(qi)包(bao)線(xian)(xian)后，需用0.92㎜銅(tong)(tong)線(xian)(xian)代替(ti)。
