一、漆包銅線和漆包鋁線怎么區分

漆(qi)包(bao)線(xian)按照材質不同(tong)有銅線(xian)、鋁(lv)(lv)(lv)線(xian)、銅包(bao)鋁(lv)(lv)(lv)線(xian)等多種，其中(zhong)比較(jiao)常(chang)用(yong)的是銅線(xian)和鋁(lv)(lv)(lv)線(xian)，漆(qi)包(bao)銅線(xian)和漆(qi)包(bao)鋁(lv)(lv)(lv)線(xian)性(xing)能有所不同(tong)，那么怎(zen)么區分漆(qi)包(bao)銅線(xian)和鋁(lv)(lv)(lv)線(xian)呢？

取一小(xiao)段(duan)漆(qi)包(bao)(bao)(bao)線，用打火機(ji)直接(jie)燒線頭(tou)，當(dang)燒出的(de)(de)線頭(tou)變成(cheng)(cheng)灰(hui)或灰(hui)色(se)(se)渣狀時，此(ci)(ci)線為(wei)鋁漆(qi)包(bao)(bao)(bao)線或銅包(bao)(bao)(bao)鋁漆(qi)包(bao)(bao)(bao)線；當(dang)燒出的(de)(de)線頭(tou)變成(cheng)(cheng)球狀或只燒去(qu)漆(qi)層而露(lu)出紅色(se)(se)金(jin)屬線狀，此(ci)(ci)線為(wei)銅漆(qi)包(bao)(bao)(bao)線。

二、漆包銅線和漆包鋁線哪個好

漆包(bao)線(xian)銅(tong)(tong)線(xian)和鋁線(xian)相比，各有(you)各的(de)好(hao)(hao)處：銅(tong)(tong)比鋁的(de)導電性要(yao)好(hao)(hao)、抗拉強度高、耐溫高，而缺點(dian)是(shi)銅(tong)(tong)的(de)成本高、比鋁重。不過(guo)整體來(lai)說，還(huan)是(shi)漆包(bao)銅(tong)(tong)線(xian)要(yao)好(hao)(hao)一些(xie)。

除(chu)了銅線和(he)鋁(lv)線的(de)截(jie)流量和(he)材(cai)質不同以(yi)外，由于漆包鋁(lv)線質量更(geng)輕，機械強(qiang)度(du)較差，在接(jie)(jie)駁線端極容易氧化，接(jie)(jie)駁線端氧化后會出現溫度(du)升高、接(jie)(jie)觸不良(liang)等(deng)情況，是引起故(gu)障（斷(duan)電或斷(duan)線）的(de)多發點。因此，一些比較重要的(de)領域都用的(de)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(tong)＝(ρ銅(tong)/ρ鋁)/2*D鋁

D銅：銅線(xian)直(zhi)徑；D鋁(lv)(lv)：鋁(lv)(lv)線(xian)直(zhi)徑；ρ鋁(lv)(lv)：鋁(lv)(lv)的電(dian)(dian)阻率(lv)，取(qu)1/35.5；ρ銅：銅的電(dian)(dian)阻率(lv)，取(qu)1/58。

比如，使(shi)用(yong)1.18㎜的(de)鋁漆(qi)包(bao)(bao)線(xian)(xian)，改為使(shi)用(yong)銅(tong)(tong)線(xian)(xian)時，銅(tong)(tong)線(xian)(xian)的(de)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)(bao)線(xian)(xian)改為銅(tong)(tong)漆(qi)包(bao)(bao)線(xian)(xian)后，需用(yong)0.92㎜銅(tong)(tong)線(xian)(xian)代(dai)替。
