電線(xian)電纜的區別(bie)有哪些(xie)？

廣義上(shang)，人們將電(dian)(dian)(dian)線和(he)(he)電(dian)(dian)(dian)纜(lan)(lan)一致稱為(wei)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)(lan)。電(dian)(dian)(dian)線和(he)(he)電(dian)(dian)(dian)纜(lan)(lan)之(zhi)間，沒有準確且固定的概念區分，一般(ban)(ban)僅以(yi)日常經驗來進行區分。在狹(xia)義上(shang)，分為(wei)電(dian)(dian)(dian)線和(he)(he)電(dian)(dian)(dian)纜(lan)(lan)，電(dian)(dian)(dian)線和(he)(he)電(dian)(dian)(dian)纜(lan)(lan)一般(ban)(ban)都(dou)是由電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)(lan)導(dao)體、絕(jue)緣層(ceng)和(he)(he)護套層(ceng)三個(ge)部分組成(cheng)。

下面沈(shen)陽電(dian)線電(dian)纜廠(chang)小(xiao)編分別從材料、用處及結(jie)構(gou)上介(jie)紹一下兩者的區別

1、材料的(de)區別 

電(dian)線(xian)(xian)(xian)(xian)用于承(cheng)載電(dian)流(liu)的(de)導(dao)電(dian)金屬線(xian)(xian)(xian)(xian)材。有實(shi)心(xin)的(de)、絞合的(de)或(huo)箔片編織的(de)等各種(zhong)形式。按絕(jue)(jue)緣(yuan)情況分(fen)為(wei)裸電(dian)線(xian)(xian)(xian)(xian)和絕(jue)(jue)緣(yuan)電(dian)線(xian)(xian)(xian)(xian)兩(liang)大類。電(dian)纜由(you)一根或(huo)多根相互絕(jue)(jue)緣(yuan)的(de)導(dao)電(dian)線(xian)(xian)(xian)(xian)心(xin)置于密封護(hu)套中構成的(de)絕(jue)(jue)緣(yuan)導(dao)線(xian)(xian)(xian)(xian)。其外可加維(wei)護(hu)覆蓋層，電(dian)線(xian)(xian)(xian)(xian)與(yu)電(dian)纜的(de)區別在于電(dian)線(xian)(xian)(xian)(xian)的(de)尺寸一般較小、結構較為(wei)簡(jian)單。但有時也將電(dian)纜歸入廣(guang)義的(de)電(dian)線(xian)(xian)(xian)(xian)之列。

2、用處的區別 

裸電(dian)(dian)(dian)(dian)線不包任何絕緣或維護(hu)層的(de)電(dian)(dian)(dian)(dian)線。除(chu)作(zuo)為傳輸電(dian)(dian)(dian)(dian)能和(he)信息(xi)的(de)導(dao)(dao)線外，還可用(yong)于(yu)制作(zuo)電(dian)(dian)(dian)(dian)機﹑電(dian)(dian)(dian)(dian)器的(de)構(gou)件和(he)連(lian)接線。一般用(yong)銅﹑鋁﹑銅合(he)金(jin)﹑鋁合(he)金(jin)。此外，還有各種適用(yong)于(yu)特(te)種要求的(de)絕緣電(dian)(dian)(dian)(dian)線，如轎(jiao)車用(yong)低壓電(dian)(dian)(dian)(dian)線、轎(jiao)車用(yong)高壓點火線、電(dian)(dian)(dian)(dian)機電(dian)(dian)(dian)(dian)器引接線、航(hang)空導(dao)(dao)線、補償導(dao)(dao)線等(deng)(deng)。電(dian)(dian)(dian)(dian)纜(lan)(lan)用(yong)于(yu)傳輸、分配電(dian)(dian)(dian)(dian)能或傳送電(dian)(dian)(dian)(dian)信號(hao)。電(dian)(dian)(dian)(dian)纜(lan)(lan)按其用(yong)處可分為電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)纜(lan)(lan)、通(tong)信電(dian)(dian)(dian)(dian)纜(lan)(lan)和(he)控制電(dian)(dian)(dian)(dian)纜(lan)(lan)等(deng)(deng)。

3、結構(gou)的區別 

電(dian)纜一般(ban)有2層以(yi)上的絕緣，多(duo)數是多(duo)芯結構，繞(rao)在電(dian)纜盤(pan)上，長度一般(ban)大于100米。電(dian)線一般(ban)是單層絕緣，單芯，無(wu)線盤(pan)。
