電線電纜的區別有(you)哪些？

廣義上，人們將(jiang)電(dian)線(xian)(xian)和(he)(he)電(dian)纜(lan)一(yi)致稱(cheng)為電(dian)線(xian)(xian)電(dian)纜(lan)。電(dian)線(xian)(xian)和(he)(he)電(dian)纜(lan)之間，沒有準確且固(gu)定(ding)的(de)概(gai)念區分(fen)，一(yi)般僅以日常經驗來(lai)進行區分(fen)。在狹義上，分(fen)為電(dian)線(xian)(xian)和(he)(he)電(dian)纜(lan)，電(dian)線(xian)(xian)和(he)(he)電(dian)纜(lan)一(yi)般都是由(you)電(dian)線(xian)(xian)電(dian)纜(lan)導體、絕緣層(ceng)和(he)(he)護套層(ceng)三(san)個部分(fen)組成。

下面沈(shen)陽電線電纜(lan)廠小編分別從材料、用處(chu)及結構上(shang)介紹一下兩者(zhe)的區別

1、材料(liao)的區別 

電(dian)(dian)(dian)(dian)線(xian)用(yong)于(yu)承載電(dian)(dian)(dian)(dian)流的(de)導電(dian)(dian)(dian)(dian)金屬線(xian)材。有(you)(you)實(shi)心(xin)的(de)、絞合(he)的(de)或箔片編織的(de)等各(ge)種形式(shi)。按絕緣(yuan)情況分(fen)為(wei)裸電(dian)(dian)(dian)(dian)線(xian)和(he)絕緣(yuan)電(dian)(dian)(dian)(dian)線(xian)兩大類。電(dian)(dian)(dian)(dian)纜由一(yi)根或多根相互絕緣(yuan)的(de)導電(dian)(dian)(dian)(dian)線(xian)心(xin)置于(yu)密封護套中(zhong)構成的(de)絕緣(yuan)導線(xian)。其(qi)外可(ke)加維(wei)護覆蓋層，電(dian)(dian)(dian)(dian)線(xian)與電(dian)(dian)(dian)(dian)纜的(de)區別在于(yu)電(dian)(dian)(dian)(dian)線(xian)的(de)尺(chi)寸(cun)一(yi)般較(jiao)小、結構較(jiao)為(wei)簡單。但有(you)(you)時也將電(dian)(dian)(dian)(dian)纜歸(gui)入廣義的(de)電(dian)(dian)(dian)(dian)線(xian)之列(lie)。

2、用處的區別 

裸電(dian)(dian)(dian)線(xian)不包任何(he)絕緣或維護層的(de)電(dian)(dian)(dian)線(xian)。除作(zuo)為(wei)傳輸(shu)(shu)電(dian)(dian)(dian)能(neng)和(he)信(xin)息的(de)導(dao)線(xian)外，還可用(yong)(yong)(yong)于制作(zuo)電(dian)(dian)(dian)機(ji)﹑電(dian)(dian)(dian)器(qi)(qi)的(de)構件和(he)連接線(xian)。一(yi)般用(yong)(yong)(yong)銅﹑鋁(lv)(lv)﹑銅合(he)(he)金(jin)﹑鋁(lv)(lv)合(he)(he)金(jin)。此外，還有各種適用(yong)(yong)(yong)于特(te)種要求的(de)絕緣電(dian)(dian)(dian)線(xian)，如轎車(che)(che)用(yong)(yong)(yong)低壓電(dian)(dian)(dian)線(xian)、轎車(che)(che)用(yong)(yong)(yong)高壓點火線(xian)、電(dian)(dian)(dian)機(ji)電(dian)(dian)(dian)器(qi)(qi)引接線(xian)、航(hang)空(kong)導(dao)線(xian)、補償(chang)導(dao)線(xian)等(deng)。電(dian)(dian)(dian)纜用(yong)(yong)(yong)于傳輸(shu)(shu)、分配電(dian)(dian)(dian)能(neng)或傳送電(dian)(dian)(dian)信(xin)號。電(dian)(dian)(dian)纜按其用(yong)(yong)(yong)處可分為(wei)電(dian)(dian)(dian)力電(dian)(dian)(dian)纜、通信(xin)電(dian)(dian)(dian)纜和(he)控制電(dian)(dian)(dian)纜等(deng)。

3、結構的區(qu)別 

電纜一般有(you)2層以上的絕緣(yuan)(yuan)，多數是(shi)多芯結構，繞在電纜盤(pan)上，長度一般大于100米。電線一般是(shi)單(dan)層絕緣(yuan)(yuan)，單(dan)芯，無(wu)線盤(pan)。
