電線(xian)電纜的區別有哪些？

廣義上(shang)，人們將電線(xian)和(he)(he)(he)(he)(he)電纜一致稱(cheng)為(wei)電線(xian)電纜。電線(xian)和(he)(he)(he)(he)(he)電纜之間，沒有準確且固(gu)定的概念(nian)區分(fen)，一般僅(jin)以日(ri)常經驗(yan)來進行區分(fen)。在狹義上(shang)，分(fen)為(wei)電線(xian)和(he)(he)(he)(he)(he)電纜，電線(xian)和(he)(he)(he)(he)(he)電纜一般都(dou)是(shi)由電線(xian)電纜導(dao)體、絕緣層和(he)(he)(he)(he)(he)護(hu)套(tao)層三個部分(fen)組成。

下(xia)面沈陽電(dian)線(xian)電(dian)纜廠小(xiao)編(bian)分別(bie)從材料、用處及(ji)結構(gou)上(shang)介紹一下(xia)兩者的(de)區別(bie)

1、材料的(de)區別 

電(dian)(dian)(dian)線(xian)用于承載(zai)電(dian)(dian)(dian)流的(de)導電(dian)(dian)(dian)金(jin)屬線(xian)材。有實心的(de)、絞合的(de)或(huo)箔(bo)片編織的(de)等各(ge)種形式。按絕(jue)(jue)緣(yuan)(yuan)情況(kuang)分為裸電(dian)(dian)(dian)線(xian)和絕(jue)(jue)緣(yuan)(yuan)電(dian)(dian)(dian)線(xian)兩(liang)大類。電(dian)(dian)(dian)纜(lan)由(you)一(yi)根(gen)或(huo)多(duo)根(gen)相互絕(jue)(jue)緣(yuan)(yuan)的(de)導電(dian)(dian)(dian)線(xian)心置于密封護套中構(gou)成的(de)絕(jue)(jue)緣(yuan)(yuan)導線(xian)。其外可加維護覆(fu)蓋層，電(dian)(dian)(dian)線(xian)與電(dian)(dian)(dian)纜(lan)的(de)區(qu)別在(zai)于電(dian)(dian)(dian)線(xian)的(de)尺寸一(yi)般較(jiao)(jiao)小(xiao)、結(jie)構(gou)較(jiao)(jiao)為簡單。但有時也將電(dian)(dian)(dian)纜(lan)歸(gui)入廣義的(de)電(dian)(dian)(dian)線(xian)之列。

2、用處的(de)區(qu)別 

裸電(dian)(dian)(dian)(dian)線(xian)(xian)不包任何絕(jue)緣或(huo)維護(hu)層的電(dian)(dian)(dian)(dian)線(xian)(xian)。除作(zuo)為傳輸(shu)電(dian)(dian)(dian)(dian)能(neng)和(he)信(xin)息的導(dao)線(xian)(xian)外，還可(ke)用于(yu)制作(zuo)電(dian)(dian)(dian)(dian)機(ji)﹑電(dian)(dian)(dian)(dian)器的構件(jian)和(he)連(lian)接線(xian)(xian)。一般用銅﹑鋁﹑銅合金(jin)﹑鋁合金(jin)。此外，還有各種適用于(yu)特種要求的絕(jue)緣電(dian)(dian)(dian)(dian)線(xian)(xian)，如轎車(che)用低壓(ya)電(dian)(dian)(dian)(dian)線(xian)(xian)、轎車(che)用高壓(ya)點火線(xian)(xian)、電(dian)(dian)(dian)(dian)機(ji)電(dian)(dian)(dian)(dian)器引(yin)接線(xian)(xian)、航空導(dao)線(xian)(xian)、補償導(dao)線(xian)(xian)等(deng)。電(dian)(dian)(dian)(dian)纜用于(yu)傳輸(shu)、分配電(dian)(dian)(dian)(dian)能(neng)或(huo)傳送(song)電(dian)(dian)(dian)(dian)信(xin)號。電(dian)(dian)(dian)(dian)纜按其(qi)用處可(ke)分為電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)纜、通(tong)信(xin)電(dian)(dian)(dian)(dian)纜和(he)控制電(dian)(dian)(dian)(dian)纜等(deng)。

3、結構的區別 

電(dian)(dian)纜一般有2層以上的絕緣，多數是多芯結構，繞在電(dian)(dian)纜盤(pan)上，長(chang)度一般大于100米。電(dian)(dian)線(xian)一般是單層絕緣，單芯，無線(xian)盤(pan)。
