電(dian)線電(dian)纜的區別(bie)有哪些？

廣義上(shang)，人們將電(dian)線(xian)和(he)(he)電(dian)纜一致稱為電(dian)線(xian)電(dian)纜。電(dian)線(xian)和(he)(he)電(dian)纜之間，沒有(you)準確且固定(ding)的概念(nian)區分(fen)(fen)(fen)，一般僅以日常經(jing)驗來(lai)進(jin)行區分(fen)(fen)(fen)。在狹義上(shang)，分(fen)(fen)(fen)為電(dian)線(xian)和(he)(he)電(dian)纜，電(dian)線(xian)和(he)(he)電(dian)纜一般都是(shi)由(you)電(dian)線(xian)電(dian)纜導體、絕緣(yuan)層(ceng)和(he)(he)護套層(ceng)三個部分(fen)(fen)(fen)組成。

下(xia)面沈陽電(dian)線(xian)電(dian)纜廠小(xiao)編分別從材料、用處及結(jie)構上介紹一下(xia)兩者的區別

1、材料(liao)的區別(bie) 

電(dian)線用于承載電(dian)流的(de)導電(dian)金屬線材。有實心(xin)的(de)、絞(jiao)合(he)的(de)或箔(bo)片編織的(de)等(deng)各種(zhong)形式。按絕緣(yuan)情(qing)況(kuang)分為裸(luo)電(dian)線和絕緣(yuan)電(dian)線兩大類。電(dian)纜由一根(gen)或多根(gen)相(xiang)互(hu)絕緣(yuan)的(de)導電(dian)線心(xin)置于密封護(hu)套(tao)中構成的(de)絕緣(yuan)導線。其外可(ke)加維(wei)護(hu)覆蓋層，電(dian)線與電(dian)纜的(de)區別在于電(dian)線的(de)尺寸一般較小、結構較為簡單。但有時也將電(dian)纜歸入廣義的(de)電(dian)線之列。

2、用處(chu)的區別 

裸電(dian)(dian)(dian)線(xian)(xian)(xian)不包(bao)任(ren)何絕(jue)緣或維護(hu)層的電(dian)(dian)(dian)線(xian)(xian)(xian)。除作為(wei)傳(chuan)(chuan)輸(shu)電(dian)(dian)(dian)能(neng)和信息的導(dao)線(xian)(xian)(xian)外(wai)，還可用于制作電(dian)(dian)(dian)機﹑電(dian)(dian)(dian)器的構件和連(lian)接(jie)線(xian)(xian)(xian)。一般用銅﹑鋁﹑銅合(he)(he)金﹑鋁合(he)(he)金。此外(wai)，還有各種適用于特種要求(qiu)的絕(jue)緣電(dian)(dian)(dian)線(xian)(xian)(xian)，如(ru)轎(jiao)車用低(di)壓電(dian)(dian)(dian)線(xian)(xian)(xian)、轎(jiao)車用高壓點火線(xian)(xian)(xian)、電(dian)(dian)(dian)機電(dian)(dian)(dian)器引(yin)接(jie)線(xian)(xian)(xian)、航空導(dao)線(xian)(xian)(xian)、補(bu)償導(dao)線(xian)(xian)(xian)等。電(dian)(dian)(dian)纜(lan)用于傳(chuan)(chuan)輸(shu)、分(fen)配(pei)電(dian)(dian)(dian)能(neng)或傳(chuan)(chuan)送電(dian)(dian)(dian)信號。電(dian)(dian)(dian)纜(lan)按其用處可分(fen)為(wei)電(dian)(dian)(dian)力電(dian)(dian)(dian)纜(lan)、通信電(dian)(dian)(dian)纜(lan)和控(kong)制電(dian)(dian)(dian)纜(lan)等。

3、結構(gou)的(de)區別(bie) 

電纜一(yi)般(ban)有2層(ceng)以上的(de)絕緣，多數是多芯(xin)結構，繞(rao)在(zai)電纜盤上，長度一(yi)般(ban)大于100米。電線(xian)一(yi)般(ban)是單層(ceng)絕緣，單芯(xin)，無線(xian)盤。
