銅(tong)芯(xin)電(dian)纜(lan)(lan)對比(bi)鋁(lv)芯(xin)電(dian)纜(lan)(lan)的幾點優(you)勢？1。電(dian)阻率低(di)：鋁(lv)芯(xin)電(dian)纜(lan)(lan)的電(dian)阻率比(bi)銅(tong)芯(xin)電(dian)纜(lan)(lan)約高(gao)(gao)1。68倍。2。延(yan)展性好(hao)：銅(tong)合(he)金(jin)的延(yan)展率為(wei)20~40%，高(gao)(gao)溫(wen)電(dian)線(xian)電(dian)纜(lan)(lan)廠，電(dian)工用銅(tong)的延(yan)展率在30%以上，而鋁(lv)合(he)金(jin)僅為(wei)18%。3。強度高(gao)(gao)：常溫(wen)下(xia)的允許應力，銅(tong)比(bi)鋁(lv)分別高(gao)(gao)出7~28%。特(te)別是高(gao)(gao)溫(wen)下(xia)的應力，兩(liang)者相(xiang)差更(geng)是甚遠。4。抗1疲(pi)勞：鋁(lv)材(cai)反復折彎(wan)易斷裂(lie)，銅(tong)則不易。彈性指(zhi)標(biao)方面，銅(tong)也比(bi)鋁(lv)高(gao)(gao)約1。7~1。8倍。5。穩定性好(hao)，耐(nai)腐(fu)(fu)蝕(shi)：銅(tong)芯(xin)抗1氧化，耐(nai)腐(fu)(fu)蝕(shi)，而鋁(lv)芯(xin)容易受氧化和腐(fu)(fu)蝕(shi)。

電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)作(zuo)為(wei)電(dian)(dian)(dian)(dian)力傳輸的(de)主要載(zai)體，廣泛(fan)應用(yong)于電(dian)(dian)(dian)(dian)器(qi)裝(zhuang)(zhuang)備(bei)、照明線(xian)(xian)(xian)路、家用(yong)電(dian)(dian)(dian)(dian)器(qi)等方面，其質量(liang)的(de)好(hao)壞直接影響到工程質量(liang)及消(xiao)費(fei)者的(de)生命財產安全。在市場上有(you)很多電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)品(pin)種(zhong)，合肥(fei)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)，要根據(ju)自己(ji)的(de)用(yong)電(dian)(dian)(dian)(dian)負荷來采(cai)用(yong)合適的(de)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)。鑒別電(dian)(dian)(dian)(dian)纜(lan)的(de)好(hao)方法：1、看包裝(zhuang)(zhuang)，的(de)電(dian)(dian)(dian)(dian)纜(lan)往(wang)往(wang)做都比較好(hao)、整齊，手拿上去有(you)質量(liang)感。2、要打開(kai)包裝(zhuang)(zhuang)看一(yi)下里面的(de)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)了，電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)品(pin)牌有(you)哪些，的(de)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)1。

我(wo)們(men)知(zhi)道現(xian)(xian)在(zai)生活離不(bu)(bu)開(kai)電(dian)當然(ran)就離不(bu)(bu)開(kai)電(dian)線(xian)電(dian)纜，由于使用(yong)場合的(de)(de)不(bu)(bu)同(tong)對于電(dian)線(xian)電(dian)纜的(de)(de)選用(yong)也(ye)是有(you)(you)區別的(de)(de)，高壓電(dian)纜，變(bian)頻電(dian)纜，阻燃電(dian)纜等(deng)等(deng)，這些(xie)不(bu)(bu)同(tong)特性的(de)(de)電(dian)纜應用(yong)場所(suo)有(you)(you)所(suo)不(bu)(bu)同(tong)。電(dian)線(xian)電(dian)纜的(de)(de)品(pin)種非常(chang)多，性能(neng)要求(qiu)特別高，如導體用(yong)銅，電(dian)纜電(dian)線(xian)報(bao)價，要求(qiu)銅的(de)(de)純度要在(zai)99。95%以上，有(you)(you)的(de)(de)產(chan)品(pin)要采用(yong)無氧高純銅。我(wo)們(men)對于電(dian)線(xian)電(dian)纜的(de)(de)挑選非常(chang)的(de)(de)嚴(yan)謹，因為(wei)如果(guo)稍微不(bu)(bu)慎可(ke)能(neng)會(hui)造成安全事(shi)故。所(suo)以一旦(dan)電(dian)線(xian)電(dian)纜出現(xian)(xian)什么異常(chang)，一定要及時的(de)(de)找出原因并解決。
