一、漆包銅線和漆包鋁線怎么區分

漆(qi)包(bao)線(xian)(xian)按(an)照材質不同有銅(tong)線(xian)(xian)、鋁(lv)(lv)(lv)線(xian)(xian)、銅(tong)包(bao)鋁(lv)(lv)(lv)線(xian)(xian)等多(duo)種(zhong)，其(qi)中(zhong)比較常用(yong)的是銅(tong)線(xian)(xian)和鋁(lv)(lv)(lv)線(xian)(xian)，漆(qi)包(bao)銅(tong)線(xian)(xian)和漆(qi)包(bao)鋁(lv)(lv)(lv)線(xian)(xian)性(xing)能有所不同，那么怎么區分漆(qi)包(bao)銅(tong)線(xian)(xian)和鋁(lv)(lv)(lv)線(xian)(xian)呢？

取一小段漆(qi)包(bao)(bao)(bao)線(xian)(xian)，用打火機直接(jie)燒(shao)線(xian)(xian)頭，當燒(shao)出(chu)的線(xian)(xian)頭變成灰或(huo)灰色渣狀時(shi)，此(ci)線(xian)(xian)為(wei)鋁漆(qi)包(bao)(bao)(bao)線(xian)(xian)或(huo)銅包(bao)(bao)(bao)鋁漆(qi)包(bao)(bao)(bao)線(xian)(xian)；當燒(shao)出(chu)的線(xian)(xian)頭變成球狀或(huo)只燒(shao)去漆(qi)層而露出(chu)紅色金屬線(xian)(xian)狀，此(ci)線(xian)(xian)為(wei)銅漆(qi)包(bao)(bao)(bao)線(xian)(xian)。

二、漆包銅線和漆包鋁線哪個好

漆包線銅(tong)(tong)線和鋁(lv)線相比，各(ge)有各(ge)的(de)好處：銅(tong)(tong)比鋁(lv)的(de)導電性要(yao)好、抗拉強度(du)高、耐溫(wen)高，而(er)缺點(dian)是(shi)銅(tong)(tong)的(de)成本高、比鋁(lv)重。不(bu)過(guo)整體來說(shuo)，還是(shi)漆包銅(tong)(tong)線要(yao)好一些。

除了銅線(xian)(xian)和鋁線(xian)(xian)的(de)(de)截流量(liang)和材質(zhi)(zhi)不同以(yi)外，由于漆包鋁線(xian)(xian)質(zhi)(zhi)量(liang)更輕，機械強度(du)較差，在接(jie)駁線(xian)(xian)端極(ji)容易氧(yang)化，接(jie)駁線(xian)(xian)端氧(yang)化后會出現溫度(du)升高、接(jie)觸不良等情況，是引起故(gu)障（斷電或斷線(xian)(xian)）的(de)(de)多發(fa)點。因(yin)此，一些比較重要(yao)的(de)(de)領域都用的(de)(de)是漆包銅線(xian)(xian)。

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(lv))/2*D鋁(lv)

D銅(tong)(tong)：銅(tong)(tong)線直徑(jing)；D鋁(lv)：鋁(lv)線直徑(jing)；ρ鋁(lv)：鋁(lv)的電阻率(lv)，取1/35.5；ρ銅(tong)(tong)：銅(tong)(tong)的電阻率(lv)，取1/58。

比(bi)如，使用1.18㎜的(de)鋁漆包(bao)(bao)線(xian)(xian)(xian)，改(gai)為(wei)使用銅線(xian)(xian)(xian)時，銅線(xian)(xian)(xian)的(de)線(xian)(xian)(xian)徑為(wei)D銅=(35.5/58)1/2*1.18=0.61211/2*1.18=0.7823*1.18=0.92，即1.18㎜鋁漆包(bao)(bao)線(xian)(xian)(xian)改(gai)為(wei)銅漆包(bao)(bao)線(xian)(xian)(xian)后，需用0.92㎜銅線(xian)(xian)(xian)代替(ti)。
