電線和電纜的區別

1、材料的區別 

電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)用于承載(zai)電(dian)(dian)(dian)(dian)流的(de)導(dao)電(dian)(dian)(dian)(dian)金屬線(xian)(xian)(xian)(xian)(xian)材。有實心的(de)、絞合的(de)或(huo)箔片編織的(de)等各種(zhong)形(xing)式。按絕緣(yuan)(yuan)狀況(kuang)分為(wei)裸電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)和絕緣(yuan)(yuan)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)兩大類。電(dian)(dian)(dian)(dian)纜(lan)由一(yi)根(gen)或(huo)多(duo)根(gen)相互絕緣(yuan)(yuan)的(de)導(dao)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)心置于密封(feng)護(hu)套(tao)中構成(cheng)的(de)絕緣(yuan)(yuan)導(dao)線(xian)(xian)(xian)(xian)(xian)。其外可加保護(hu)覆蓋層，電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)與電(dian)(dian)(dian)(dian)纜(lan)的(de)區別在(zai)于電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)的(de)尺(chi)寸一(yi)般(ban)較(jiao)小(xiao)、結(jie)構較(jiao)為(wei)簡單。但有時也將電(dian)(dian)(dian)(dian)纜(lan)歸(gui)入廣義(yi)的(de)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)之列。

2、用途的區別 

裸電(dian)(dian)(dian)線(xian)(xian)(xian)不包任何絕(jue)緣(yuan)或保(bao)護層的(de)電(dian)(dian)(dian)線(xian)(xian)(xian)。除作為(wei)傳輸電(dian)(dian)(dian)能(neng)和(he)(he)信息的(de)導線(xian)(xian)(xian)外，還可用(yong)(yong)于(yu)制造(zao)電(dian)(dian)(dian)機(ji)(ji)﹑電(dian)(dian)(dian)器(qi)的(de)構件(jian)和(he)(he)連接線(xian)(xian)(xian)。一般用(yong)(yong)銅(tong)(tong)﹑鋁(lv)(lv)﹑銅(tong)(tong)合金﹑鋁(lv)(lv)合金。此(ci)外，還有各種適(shi)用(yong)(yong)于(yu)特種要求的(de)絕(jue)緣(yuan)電(dian)(dian)(dian)線(xian)(xian)(xian)，如汽車用(yong)(yong)低(di)壓(ya)電(dian)(dian)(dian)線(xian)(xian)(xian)、汽車用(yong)(yong)高壓(ya)點火線(xian)(xian)(xian)、電(dian)(dian)(dian)機(ji)(ji)電(dian)(dian)(dian)器(qi)引(yin)接線(xian)(xian)(xian)、航空導線(xian)(xian)(xian)、補(bu)償(chang)導線(xian)(xian)(xian)等。電(dian)(dian)(dian)纜(lan)用(yong)(yong)于(yu)傳輸、分(fen)配電(dian)(dian)(dian)能(neng)或傳送電(dian)(dian)(dian)信號。電(dian)(dian)(dian)纜(lan)按其用(yong)(yong)途可分(fen)為(wei)電(dian)(dian)(dian)力電(dian)(dian)(dian)纜(lan)、通信電(dian)(dian)(dian)纜(lan)和(he)(he)控制電(dian)(dian)(dian)纜(lan)等。

3、結構的區(qu)別 

電纜一般(ban)有2層以(yi)上(shang)的絕(jue)緣，多數是(shi)多芯結構，繞在電纜盤上(shang)，長度一般(ban)大于100米。電線一般(ban)是(shi)單(dan)層絕(jue)緣，單(dan)芯，100米一卷，無線盤。
