一、漆包銅線和漆包鋁線怎么區分
漆(qi)包線(xian)按(an)照材質不同(tong)有銅(tong)(tong)線(xian)、鋁(lv)線(xian)、銅(tong)(tong)包鋁(lv)線(xian)等多種,其中比較(jiao)常(chang)用的是銅(tong)(tong)線(xian)和鋁(lv)線(xian),漆(qi)包銅(tong)(tong)線(xian)和漆(qi)包鋁(lv)線(xian)性能有所不同(tong),那么怎(zen)么區分漆(qi)包銅(tong)(tong)線(xian)和鋁(lv)線(xian)呢?
取一小段漆(qi)(qi)包(bao)(bao)線(xian)(xian)(xian),用打火機直(zhi)接燒(shao)線(xian)(xian)(xian)頭(tou),當燒(shao)出的(de)線(xian)(xian)(xian)頭(tou)變成灰或灰色渣狀時(shi),此線(xian)(xian)(xian)為鋁漆(qi)(qi)包(bao)(bao)線(xian)(xian)(xian)或銅包(bao)(bao)鋁漆(qi)(qi)包(bao)(bao)線(xian)(xian)(xian);當燒(shao)出的(de)線(xian)(xian)(xian)頭(tou)變成球狀或只(zhi)燒(shao)去漆(qi)(qi)層(ceng)而露出紅(hong)色金(jin)屬線(xian)(xian)(xian)狀,此線(xian)(xian)(xian)為銅漆(qi)(qi)包(bao)(bao)線(xian)(xian)(xian)。
二、漆包銅線和漆包鋁線哪個好
漆包線(xian)銅(tong)線(xian)和(he)鋁(lv)線(xian)相比,各有(you)各的(de)好處:銅(tong)比鋁(lv)的(de)導電性要好、抗拉強度高(gao)、耐溫高(gao),而缺(que)點是銅(tong)的(de)成本高(gao)、比鋁(lv)重。不過(guo)整體來說,還是漆包銅(tong)線(xian)要好一些。
除了銅(tong)(tong)線(xian)(xian)和鋁線(xian)(xian)的(de)截流(liu)量和材質不(bu)同以外,由于漆包鋁線(xian)(xian)質量更輕,機械強度較(jiao)差(cha),在接駁(bo)線(xian)(xian)端極容易氧(yang)化(hua),接駁(bo)線(xian)(xian)端氧(yang)化(hua)后會出現溫(wen)度升高、接觸不(bu)良等情(qing)況(kuang),是引起故障(zhang)(斷電或斷線(xian)(xian))的(de)多(duo)發點(dian)。因(yin)此,一些比較(jiao)重要的(de)領域都用的(de)是漆包銅(tong)(tong)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(tong)=(ρ銅(tong)/ρ鋁(lv))/2*D鋁(lv)
D銅(tong):銅(tong)線直徑(jing)(jing);D鋁:鋁線直徑(jing)(jing);ρ鋁:鋁的電阻率,取(qu)(qu)1/35.5;ρ銅(tong):銅(tong)的電阻率,取(qu)(qu)1/58。
比如(ru),使(shi)(shi)用1.18㎜的(de)鋁漆(qi)包線(xian)(xian),改(gai)為使(shi)(shi)用銅(tong)(tong)(tong)線(xian)(xian)時,銅(tong)(tong)(tong)線(xian)(xian)的(de)線(xian)(xian)徑為D銅(tong)(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)包線(xian)(xian)改(gai)為銅(tong)(tong)(tong)漆(qi)包線(xian)(xian)后,需用0.92㎜銅(tong)(tong)(tong)線(xian)(xian)代(dai)替。
