電(dian)纜和電(dian)線有(you)啥區別？

1---材(cai)料的區別

電(dian)(dian)(dian)(dian)線用于承載電(dian)(dian)(dian)(dian)流的(de)導電(dian)(dian)(dian)(dian)金(jin)屬(shu)線材。有實心的(de)﹑絞(jiao)合的(de)或(huo)箔片編織的(de)等各種形式。按(an)絕(jue)緣(yuan)狀況分為(wei)裸電(dian)(dian)(dian)(dian)線和(he)絕(jue)緣(yuan)電(dian)(dian)(dian)(dian)線兩大類。電(dian)(dian)(dian)(dian)纜由一(yi)根(gen)或(huo)多根(gen)相(xiang)互絕(jue)緣(yuan)的(de)導電(dian)(dian)(dian)(dian)線心置于密封護套中(zhong)構成的(de)絕(jue)緣(yuan)導線。其外(wai)可加保(bao)護覆(fu)蓋層，電(dian)(dian)(dian)(dian)線與(yu)電(dian)(dian)(dian)(dian)纜的(de)區別在于電(dian)(dian)(dian)(dian)線的(de)尺(chi)寸一(yi)般較小、結構較為(wei)簡單，但有時也將電(dian)(dian)(dian)(dian)纜歸入廣(guang)義的(de)電(dian)(dian)(dian)(dian)線之列(lie)。

2---用途的區別

裸電(dian)(dian)(dian)線(xian)(xian)(xian)不(bu)包任何絕(jue)緣或(huo)保(bao)護層的(de)電(dian)(dian)(dian)線(xian)(xian)(xian)。除(chu)作為(wei)傳輸電(dian)(dian)(dian)能(neng)和(he)(he)信(xin)(xin)息(xi)的(de)導線(xian)(xian)(xian)外，還(huan)可用(yong)于制(zhi)造電(dian)(dian)(dian)機﹑電(dian)(dian)(dian)器(qi)的(de)構(gou)件和(he)(he)連接線(xian)(xian)(xian)。一般(ban)用(yong)銅、鋁、銅合金、鋁合金。此(ci)外，還(huan)有各種適(shi)用(yong)于特(te)種要求的(de)絕(jue)緣電(dian)(dian)(dian)線(xian)(xian)(xian)，如汽(qi)車用(yong)低(di)壓電(dian)(dian)(dian)線(xian)(xian)(xian)、汽(qi)車用(yong)高壓點火線(xian)(xian)(xian)、電(dian)(dian)(dian)機電(dian)(dian)(dian)器(qi)引接線(xian)(xian)(xian)、航空導線(xian)(xian)(xian)、補償導線(xian)(xian)(xian)等(deng)。電(dian)(dian)(dian)纜(lan)(lan)(lan)用(yong)于傳輸、分配電(dian)(dian)(dian)能(neng)或(huo)傳送電(dian)(dian)(dian)信(xin)(xin)號。 電(dian)(dian)(dian)纜(lan)(lan)(lan)按(an)其用(yong)途可分為(wei)電(dian)(dian)(dian)力(li)電(dian)(dian)(dian)纜(lan)(lan)(lan)、通信(xin)(xin)電(dian)(dian)(dian)纜(lan)(lan)(lan)和(he)(he)控制(zhi)電(dian)(dian)(dian)纜(lan)(lan)(lan)等(deng)。

3---結構(gou)的區別

電(dian)(dian)力電(dian)(dian)纜與普通電(dian)(dian)線的(de)差(cha)別主(zhu)要(yao)是電(dian)(dian)纜尺寸較大，結構較復雜。電(dian)(dian)纜主(zhu)要(yao)由以下4部(bu)分群組(zu)成(cheng)。導(dao)電(dian)(dian)線心(xin)：用高電(dian)(dian)導(dao)率材料(liao)制(zhi)成(cheng)。絕緣(yuan)(yuan)(yuan)層(ceng)：用作(zuo)電(dian)(dian)纜的(de)絕緣(yuan)(yuan)(yuan)材料(liao)應當具有高的(de)絕緣(yuan)(yuan)(yuan)電(dian)(dian)阻，高的(de)擊穿電(dian)(dian)場強度。電(dian)(dian)纜常(chang)以絕緣(yuan)(yuan)(yuan)材料(liao)分類。

除了上(shang)面的(de)(de)區(qu)別，電(dian)(dian)纜還具有明顯的(de)(de)優(you)勢。與架空(kong)(kong)線相比，電(dian)(dian)纜的(de)(de)優(you)點是(shi)線間絕緣距離小(xiao)，占(zhan)(zhan)地空(kong)(kong)間小(xiao)，地下敷(fu)設而不占(zhan)(zhan)地面以(yi)上(shang)空(kong)(kong)間，不受周(zhou)圍環(huan)境污染影響，送電(dian)(dian)可靠性(xing)高(gao)，對(dui)人身和周(zhou)圍環(huan)境干擾小(xiao)。因此，電(dian)(dian)纜多應用于人口(kou)密(mi)集和電(dian)(dian)網稠密(mi)區(qu)及(ji)交通擁擠繁忙處。對(dui)于現代化(hua)建設有著不可忽視的(de)(de)作用。
