一、漆包銅線和漆包鋁線怎么區分
漆(qi)包(bao)線(xian)按照材質不同有(you)銅(tong)線(xian)、鋁(lv)線(xian)、銅(tong)包(bao)鋁(lv)線(xian)等(deng)多種,其中(zhong)比較常用的是銅(tong)線(xian)和(he)鋁(lv)線(xian),漆(qi)包(bao)銅(tong)線(xian)和(he)漆(qi)包(bao)鋁(lv)線(xian)性能有(you)所(suo)不同,那么(me)怎(zen)么(me)區分(fen)漆(qi)包(bao)銅(tong)線(xian)和(he)鋁(lv)線(xian)呢?
取(qu)一小段漆(qi)(qi)包(bao)(bao)線(xian),用打火機直接燒(shao)線(xian)頭,當(dang)燒(shao)出的線(xian)頭變成灰(hui)或灰(hui)色(se)渣狀(zhuang)(zhuang)時,此(ci)線(xian)為鋁漆(qi)(qi)包(bao)(bao)線(xian)或銅(tong)包(bao)(bao)鋁漆(qi)(qi)包(bao)(bao)線(xian);當(dang)燒(shao)出的線(xian)頭變成球狀(zhuang)(zhuang)或只燒(shao)去漆(qi)(qi)層而露出紅(hong)色(se)金(jin)屬線(xian)狀(zhuang)(zhuang),此(ci)線(xian)為銅(tong)漆(qi)(qi)包(bao)(bao)線(xian)。
二、漆包銅線和漆包鋁線哪個好
漆包(bao)線銅(tong)線和鋁(lv)(lv)線相比(bi),各(ge)(ge)有各(ge)(ge)的(de)好(hao)處:銅(tong)比(bi)鋁(lv)(lv)的(de)導電性要(yao)好(hao)、抗拉強度(du)高(gao)(gao)、耐溫高(gao)(gao),而缺(que)點是銅(tong)的(de)成(cheng)本高(gao)(gao)、比(bi)鋁(lv)(lv)重。不過整體來說,還是漆包(bao)銅(tong)線要(yao)好(hao)一些(xie)。
除了(le)銅線和鋁線的(de)截流量和材(cai)質不同(tong)以外(wai),由于(yu)漆包(bao)鋁線質量更輕(qing),機械強度(du)較(jiao)(jiao)差(cha),在(zai)接駁線端極容易氧化(hua),接駁線端氧化(hua)后會出現(xian)溫度(du)升高、接觸不良等情況(kuang),是引起(qi)故障(zhang)(斷電(dian)或(huo)斷線)的(de)多發點。因此,一(yi)些比(bi)較(jiao)(jiao)重要的(de)領域都用的(de)是漆包(bao)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(tong):銅(tong)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)阻(zu)率(lv),取(qu)(qu)1/35.5;ρ銅(tong):銅(tong)的電(dian)阻(zu)率(lv),取(qu)(qu)1/58。
比(bi)如,使用1.18㎜的鋁漆包(bao)(bao)線(xian),改(gai)為使用銅(tong)(tong)(tong)線(xian)時,銅(tong)(tong)(tong)線(xian)的線(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(ji)1.18㎜鋁漆包(bao)(bao)線(xian)改(gai)為銅(tong)(tong)(tong)漆包(bao)(bao)線(xian)后(hou),需用0.92㎜銅(tong)(tong)(tong)線(xian)代(dai)替。
