一、漆包銅線和漆包鋁線怎么區分

漆(qi)包(bao)線按照材質不(bu)同有銅(tong)線、鋁(lv)線、銅(tong)包(bao)鋁(lv)線等多種，其中(zhong)比較常(chang)用的(de)是銅(tong)線和鋁(lv)線，漆(qi)包(bao)銅(tong)線和漆(qi)包(bao)鋁(lv)線性能有所不(bu)同，那么怎么區分漆(qi)包(bao)銅(tong)線和鋁(lv)線呢？

取(qu)一小段漆(qi)包(bao)線(xian)(xian)(xian)，用打火機(ji)直接燒線(xian)(xian)(xian)頭(tou)，當(dang)燒出(chu)的線(xian)(xian)(xian)頭(tou)變成灰(hui)或灰(hui)色渣狀(zhuang)時(shi)，此(ci)線(xian)(xian)(xian)為(wei)鋁(lv)漆(qi)包(bao)線(xian)(xian)(xian)或銅包(bao)鋁(lv)漆(qi)包(bao)線(xian)(xian)(xian)；當(dang)燒出(chu)的線(xian)(xian)(xian)頭(tou)變成球狀(zhuang)或只燒去(qu)漆(qi)層而露出(chu)紅色金屬(shu)線(xian)(xian)(xian)狀(zhuang)，此(ci)線(xian)(xian)(xian)為(wei)銅漆(qi)包(bao)線(xian)(xian)(xian)。

二、漆包銅線和漆包鋁線哪個好

漆(qi)包線(xian)(xian)(xian)(xian)銅線(xian)(xian)(xian)(xian)和鋁(lv)線(xian)(xian)(xian)(xian)相比，各有各的(de)好處：銅比鋁(lv)的(de)導電(dian)性要好、抗(kang)拉(la)強度高(gao)(gao)、耐溫高(gao)(gao)，而缺點是(shi)銅的(de)成本高(gao)(gao)、比鋁(lv)重。不過整(zheng)體(ti)來(lai)說，還是(shi)漆(qi)包銅線(xian)(xian)(xian)(xian)要好一(yi)些。

除(chu)了銅線(xian)和鋁線(xian)的(de)截(jie)流量和材質不同以外，由于漆(qi)包鋁線(xian)質量更輕，機(ji)械強度較(jiao)差，在接駁線(xian)端極容易氧化，接駁線(xian)端氧化后會出現溫度升高、接觸不良(liang)等情況(kuang)，是引起(qi)故障(zhang)（斷電或斷線(xian)）的(de)多發點。因此(ci)，一些比較(jiao)重(zhong)要(yao)的(de)領域都用的(de)是漆(qi)包銅線(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)/2*D鋁

D銅：銅線直徑；D鋁：鋁線直徑；ρ鋁：鋁的電阻率，取1/35.5；ρ銅：銅的電阻率，取1/58。

比如，使(shi)用1.18㎜的(de)鋁漆(qi)包(bao)線(xian)，改(gai)為(wei)使(shi)用銅(tong)線(xian)時，銅(tong)線(xian)的(de)線(xian)徑(jing)為(wei)D銅(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)改(gai)為(wei)銅(tong)漆(qi)包(bao)線(xian)后(hou)，需用0.92㎜銅(tong)線(xian)代替。
