電線(xian)電纜的區別有哪些(xie)？

廣義上，人(ren)們(men)將電(dian)線(xian)和(he)電(dian)纜(lan)(lan)(lan)(lan)一(yi)致稱為電(dian)線(xian)電(dian)纜(lan)(lan)(lan)(lan)。電(dian)線(xian)和(he)電(dian)纜(lan)(lan)(lan)(lan)之間，沒有準確(que)且(qie)固定的概念區分(fen)，一(yi)般(ban)僅(jin)以日(ri)常經驗來(lai)進行(xing)區分(fen)。在狹義上，分(fen)為電(dian)線(xian)和(he)電(dian)纜(lan)(lan)(lan)(lan)，電(dian)線(xian)和(he)電(dian)纜(lan)(lan)(lan)(lan)一(yi)般(ban)都(dou)是(shi)由電(dian)線(xian)電(dian)纜(lan)(lan)(lan)(lan)導體、絕緣層和(he)護套層三個部分(fen)組(zu)成(cheng)。

下面沈陽電(dian)線(xian)電(dian)纜(lan)廠小(xiao)編分別從材料、用處及結構上介紹一下兩者的區別

1、材料的區(qu)別 

電(dian)(dian)線(xian)(xian)(xian)用于承載電(dian)(dian)流的(de)導電(dian)(dian)金屬線(xian)(xian)(xian)材(cai)。有實心的(de)、絞(jiao)合(he)的(de)或(huo)箔片編織的(de)等各種(zhong)形式(shi)。按絕(jue)(jue)緣(yuan)情況分(fen)為裸電(dian)(dian)線(xian)(xian)(xian)和絕(jue)(jue)緣(yuan)電(dian)(dian)線(xian)(xian)(xian)兩大類。電(dian)(dian)纜由(you)一(yi)根(gen)或(huo)多根(gen)相互絕(jue)(jue)緣(yuan)的(de)導電(dian)(dian)線(xian)(xian)(xian)心置于密(mi)封(feng)護套中構成的(de)絕(jue)(jue)緣(yuan)導線(xian)(xian)(xian)。其外可(ke)加維護覆蓋層，電(dian)(dian)線(xian)(xian)(xian)與電(dian)(dian)纜的(de)區別在于電(dian)(dian)線(xian)(xian)(xian)的(de)尺寸一(yi)般較(jiao)小、結構較(jiao)為簡單。但有時也將電(dian)(dian)纜歸(gui)入廣義的(de)電(dian)(dian)線(xian)(xian)(xian)之(zhi)列。

2、用處的(de)區別 

裸(luo)電(dian)(dian)線(xian)(xian)不包任何絕(jue)緣(yuan)或維護層的(de)(de)電(dian)(dian)線(xian)(xian)。除(chu)作為(wei)傳輸電(dian)(dian)能(neng)(neng)和(he)信息的(de)(de)導線(xian)(xian)外，還可用(yong)于(yu)制作電(dian)(dian)機(ji)﹑電(dian)(dian)器的(de)(de)構件和(he)連接線(xian)(xian)。一般用(yong)銅﹑鋁﹑銅合金(jin)﹑鋁合金(jin)。此外，還有(you)各(ge)種(zhong)適用(yong)于(yu)特種(zhong)要求的(de)(de)絕(jue)緣(yuan)電(dian)(dian)線(xian)(xian)，如(ru)轎車用(yong)低壓(ya)電(dian)(dian)線(xian)(xian)、轎車用(yong)高壓(ya)點(dian)火線(xian)(xian)、電(dian)(dian)機(ji)電(dian)(dian)器引接線(xian)(xian)、航(hang)空(kong)導線(xian)(xian)、補償(chang)導線(xian)(xian)等(deng)。電(dian)(dian)纜(lan)用(yong)于(yu)傳輸、分配電(dian)(dian)能(neng)(neng)或傳送電(dian)(dian)信號(hao)。電(dian)(dian)纜(lan)按(an)其用(yong)處(chu)可分為(wei)電(dian)(dian)力(li)電(dian)(dian)纜(lan)、通信電(dian)(dian)纜(lan)和(he)控制電(dian)(dian)纜(lan)等(deng)。

3、結構的區(qu)別 

電纜一般(ban)有2層以上的絕緣，多數(shu)是多芯結構，繞在電纜盤上，長度一般(ban)大于(yu)100米。電線一般(ban)是單(dan)層絕緣，單(dan)芯，無線盤。
