電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)作為(wei)電(dian)(dian)(dian)(dian)力傳(chuan)輸的(de)(de)(de)主要(yao)(yao)載體，廣泛(fan)應用(yong)(yong)(yong)于電(dian)(dian)(dian)(dian)器裝備、照明線路、家用(yong)(yong)(yong)電(dian)(dian)(dian)(dian)器等方(fang)面，其質量的(de)(de)(de)好壞直接(jie)影(ying)響到工程質量及消費者的(de)(de)(de)生命財產安(an)全。在(zai)市場上有(you)很多電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)品種，要(yao)(yao)根據自己的(de)(de)(de)用(yong)(yong)(yong)電(dian)(dian)(dian)(dian)負(fu)荷來采用(yong)(yong)(yong)合適的(de)(de)(de)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)。鑒(jian)別電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)好方(fang)法：1、看(kan)包裝，的(de)(de)(de)電(dian)(dian)(dian)(dian)纜(lan)往往做都比較好、整齊(qi)，手拿上去有(you)質量感。2、要(yao)(yao)打(da)開包裝看(kan)一下里面的(de)(de)(de)電(dian)(dian)(dian)(dian)線了，工業電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)，的(de)(de)(de)電(dian)(dian)(dian)(dian)線1。

三稱重(zhong)(zhong)量(liang)。質(zhi)量(liang)好(hao)的(de)(de)電(dian)(dian)線電(dian)(dian)纜(lan)，一般每(mei)100m重(zhong)(zhong)量(liang)都在規(gui)定(ding)的(de)(de)重(zhong)(zhong)量(liang)范(fan)圍內。質(zhi)量(liang)差(cha)的(de)(de)電(dian)(dian)線重(zhong)(zhong)量(liang)不(bu)足，要么長度不(bu)夠，pvc電(dian)(dian)線電(dian)(dian)纜(lan)，要么電(dian)(dian)線銅(tong)(tong)芯(xin)雜質(zhi)過多。四(si)比價(jia)格。購買時，要當心，別為(wei)商家標榜的(de)(de)''沖(chong)昏了頭腦，終(zhong)上當受騙。五看銅(tong)(tong)質(zhi)。合(he)格的(de)(de)銅(tong)(tong)芯(xin)電(dian)(dian)線銅(tong)(tong)芯(xin)應(ying)該是紫(zi)紅色、有光(guang)澤、手感(gan)軟。而的(de)(de)銅(tong)(tong)芯(xin)線銅(tong)(tong)芯(xin)為(wei)紫(zi)黑色、偏黃或偏白，雜質(zhi)多，機械強度差(cha)，韌(ren)性不(bu)佳(jia)，稍用力即會折斷，而且電(dian)(dian)線內常有斷線現象。

電(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)纜的(de)(de)(de)(de)(de)作(zuo)用是(shi)什么(me)?應注(zhu)意什么(me)?首(shou)先我們對(dui)(dui)電(dian)(dian)(dian)(dian)(dian)線肯定(ding)都(dou)不陌(mo)生(sheng)了。也知道一般在(zai)什么(me)場合(he)會使用到(dao)。所以對(dui)(dui)于作(zuo)用大致上我們都(dou)了解。但實質意義(yi)呢?他的(de)(de)(de)(de)(de)作(zuo)用，是(shi)能傳輸供電(dian)(dian)(dian)(dian)(dian)到(dao)各(ge)(ge)(ge)家或各(ge)(ge)(ge)個工(gong)業(ye)，電(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)纜價(jia)格表，只要用到(dao)照明的(de)(de)(de)(de)(de)地方，都(dou)要用到(dao)電(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)纜。電(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)纜用以傳輸電(dian)(dian)(dian)(dian)(dian)（磁）能，合(he)肥電(dian)(dian)(dian)(dian)(dian)線，信(xin)息和實現電(dian)(dian)(dian)(dian)(dian)磁能轉換的(de)(de)(de)(de)(de)線材產品．廣義(yi)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)纜亦簡稱為電(dian)(dian)(dian)(dian)(dian)纜．狹義(yi)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)纜是(shi)指(zhi)絕(jue)緣電(dian)(dian)(dian)(dian)(dian)纜．它可定(ding)義(yi)為：由下(xia)列部(bu)分組(zu)成(cheng)的(de)(de)(de)(de)(de)集合(he)體(ti)：一根或多根絕(jue)緣線芯，以及它們各(ge)(ge)(ge)自可能具有的(de)(de)(de)(de)(de)包覆層，總保護層及外護層．電(dian)(dian)(dian)(dian)(dian)纜亦可有附(fu)加的(de)(de)(de)(de)(de)沒有絕(jue)緣的(de)(de)(de)(de)(de)導體(ti)。
