電線和電纜的區別

1、材料的區別 

電(dian)(dian)線(xian)(xian)(xian)用(yong)于(yu)承載電(dian)(dian)流的導電(dian)(dian)金屬線(xian)(xian)(xian)材(cai)。有(you)實心(xin)的、絞(jiao)合的或箔(bo)片編(bian)織的等各種形式。按絕(jue)緣(yuan)狀況(kuang)分(fen)為(wei)(wei)裸電(dian)(dian)線(xian)(xian)(xian)和絕(jue)緣(yuan)電(dian)(dian)線(xian)(xian)(xian)兩(liang)大(da)類。電(dian)(dian)纜(lan)由(you)一根(gen)或多(duo)根(gen)相互(hu)絕(jue)緣(yuan)的導電(dian)(dian)線(xian)(xian)(xian)心(xin)置于(yu)密封護(hu)套中構(gou)成的絕(jue)緣(yuan)導線(xian)(xian)(xian)。其外可(ke)加保護(hu)覆蓋層，電(dian)(dian)線(xian)(xian)(xian)與電(dian)(dian)纜(lan)的區別在于(yu)電(dian)(dian)線(xian)(xian)(xian)的尺寸一般(ban)較小、結構(gou)較為(wei)(wei)簡單(dan)。但(dan)有(you)時也將電(dian)(dian)纜(lan)歸入(ru)廣義的電(dian)(dian)線(xian)(xian)(xian)之(zhi)列。

2、用途的區別 

裸(luo)電(dian)(dian)線(xian)(xian)(xian)不包任何絕緣或(huo)(huo)保護層的(de)電(dian)(dian)線(xian)(xian)(xian)。除作為傳輸電(dian)(dian)能和信(xin)(xin)息的(de)導線(xian)(xian)(xian)外，還可用于(yu)制(zhi)造電(dian)(dian)機﹑電(dian)(dian)器的(de)構件和連接線(xian)(xian)(xian)。一般用銅﹑鋁﹑銅合金﹑鋁合金。此外，還有各種(zhong)適(shi)用于(yu)特種(zhong)要求的(de)絕緣電(dian)(dian)線(xian)(xian)(xian)，如汽車用低壓電(dian)(dian)線(xian)(xian)(xian)、汽車用高壓點火(huo)線(xian)(xian)(xian)、電(dian)(dian)機電(dian)(dian)器引(yin)接線(xian)(xian)(xian)、航空導線(xian)(xian)(xian)、補償導線(xian)(xian)(xian)等。電(dian)(dian)纜(lan)用于(yu)傳輸、分(fen)配電(dian)(dian)能或(huo)(huo)傳送(song)電(dian)(dian)信(xin)(xin)號。電(dian)(dian)纜(lan)按其用途可分(fen)為電(dian)(dian)力電(dian)(dian)纜(lan)、通信(xin)(xin)電(dian)(dian)纜(lan)和控制(zhi)電(dian)(dian)纜(lan)等。

3、結(jie)構(gou)的區別 

電(dian)纜一(yi)(yi)般(ban)有2層(ceng)(ceng)以上的絕緣，多數是多芯結構，繞在電(dian)纜盤上，長度一(yi)(yi)般(ban)大于100米。電(dian)線(xian)一(yi)(yi)般(ban)是單層(ceng)(ceng)絕緣，單芯，100米一(yi)(yi)卷，無線(xian)盤。
