1. 看電纜電線長度：河南專業生產鋁芯線國家(jia)標準規(gui)定(ding)，電(dian)(dian)線(xian)(xian)電(dian)(dian)纜每(mei)卷100米，計量(liang)誤差不大于0.5%，也就是(shi)(shi)每(mei)卷線(xian)(xian)的(de)長度為100±0.5米，但是(shi)(shi)有(you)些(xie)(xie)商(shang)家(jia)標注的(de)是(shi)(shi)100±20米，但實(shi)(shi)際上，卻(que)只有(you)80米左右(you)。2. 看(kan)電(dian)(dian)阻(zu)值：電(dian)(dian)阻(zu)值超標的(de)話，電(dian)(dian)線(xian)(xian)就容易(yi)出(chu)現溫度過高、老(lao)化(hua)的(de)危(wei)險，而且如(ru)果電(dian)(dian)線(xian)(xian)短路的(de)話，還(huan)會引(yin)發(fa)火災。并且電(dian)(dian)阻(zu)值超標，還(huan)增加傳輸電(dian)(dian)量(liang)時(shi)的(de)消耗，增加電(dian)(dian)費(fei)，所以，我們在選(xuan)擇時(shi)，一定(ding)要留意(yi)這一點。3.看(kan)原材(cai)(cai)料：純(chun)銅(tong)芯的(de)材(cai)(cai)料導(dao)電(dian)(dian)性好，而且不易(yi)老(lao)化(hua)，更加耐用(yong)，也減少了故(gu)障發(fa)生。但是(shi)(shi)有(you)些(xie)(xie)商(shang)家(jia)，會在銅(tong)材(cai)(cai)質(zhi)中(zhong)(zhong)添加一些(xie)(xie)雜質(zhi)銅(tong)、回(hui)收(shou)銅(tong)，還(huan)有(you)的(de)劣質(zhi)產(chan)品通過降低銅(tong)芯實(shi)(shi)際截面積(ji)，來減少銅(tong)材(cai)(cai)質(zhi)的(de)用(yong)量(liang)，這樣容易(yi)導(dao)致(zhi)電(dian)(dian)線(xian)(xian)電(dian)(dian)纜用(yong)電(dian)(dian)過程中(zhong)(zhong)發(fa)熱，損壞外(wai)邊的(de)絕緣層塑料，容易(yi)讓電(dian)(dian)線(xian)(xian)老(lao)化(hua)，導(dao)致(zhi)出(chu)現漏電(dian)(dian)、短路的(de)問(wen)題(ti)。
