1、定義不同
廣(guang)義上，人(ren)們將電(dian)線(xian)和(he)(he)電(dian)纜(lan)統一稱為(wei)電(dian)線(xian)電(dian)纜(lan)。電(dian)線(xian)和(he)(he)電(dian)纜(lan)之間，沒有準(zhun)確且固定的(de)概(gai)念區分(fen)(fen)，一般僅以日常經驗來(lai)進(jin)行區分(fen)(fen)。在狹(xia)義上，分(fen)(fen)為(wei)電(dian)線(xian)和(he)(he)電(dian)纜(lan)，電(dian)線(xian)和(he)(he)電(dian)纜(lan)一般都是由(you)電(dian)線(xian)電(dian)纜(lan)導(dao)體、絕(jue)緣層和(he)(he)護套層三個(ge)部分(fen)(fen)組(zu)成(cheng)。
2、材料(liao)的區(qu)別(bie)
電線用(yong)于(yu)承載電流的(de)導電金屬線材。有實心的(de)﹑絞合的(de)或箔片編織的(de)等各種形(xing)式。按絕緣(yuan)狀況分為裸電線和絕緣(yuan)電線兩大類。
電(dian)纜(lan)(lan)由一根或多根相互(hu)絕緣的(de)(de)(de)導電(dian)線(xian)(xian)心置于(yu)密封護套中構(gou)成的(de)(de)(de)絕緣導線(xian)(xian)。其外可加保護覆蓋層，電(dian)線(xian)(xian)與電(dian)纜(lan)(lan)的(de)(de)(de)區別在(zai)于(yu)電(dian)線(xian)(xian)的(de)(de)(de)尺寸一般較(jiao)小、結構(gou)較(jiao)為簡單，但有時也將電(dian)纜(lan)(lan)歸入廣義的(de)(de)(de)電(dian)線(xian)(xian)之列。
3、用途的區別
裸電(dian)線(xian)(xian)(xian)不包任何絕緣或保護層的(de)電(dian)線(xian)(xian)(xian)。除作(zuo)為傳輸電(dian)能和信息的(de)導(dao)線(xian)(xian)(xian)外(wai)，還可(ke)用(yong)于制造電(dian)機﹑電(dian)器的(de)構件(jian)和連(lian)接(jie)線(xian)(xian)(xian)。一般用(yong)銅(tong)、鋁(lv)、銅(tong)合金(jin)、鋁(lv)合金(jin)。此外(wai)，還有各(ge)種適用(yong)于特種要(yao)求的(de)絕緣電(dian)線(xian)(xian)(xian)，如汽車(che)用(yong)低壓電(dian)線(xian)(xian)(xian)、汽車(che)用(yong)高壓點火線(xian)(xian)(xian)、電(dian)機電(dian)器引接(jie)線(xian)(xian)(xian)、航空導(dao)線(xian)(xian)(xian)、補償(chang)導(dao)線(xian)(xian)(xian)等(deng)。
電纜用于傳輸、分配電能或傳送電信號。 電纜按其用途可分為電力電纜、通信電纜和控制電纜等。
4、結構不同
電線(xian)(xian)是(shi)由一(yi)根或幾(ji)根柔軟(ruan)的(de)(de)導線(xian)(xian)組成，外面包以輕軟(ruan)的(de)(de)護(hu)層，用于承載電流的(de)(de)導電金屬(shu)線(xian)(xian)材(cai)。有實心的(de)(de)﹑絞合的(de)(de)或箔片編織的(de)(de)等(deng)各種形式(shi)。按(an)絕(jue)緣(yuan)狀況分(fen)為裸(luo)電線(xian)(xian)和絕(jue)緣(yuan)電線(xian)(xian)兩大類。
電纜由一根或多根相互絕緣的導電線(xian)心置于(yu)密封護套中(zhong)構成的絕緣導線(xian)。其(qi)外可加保(bao)護覆蓋層﹐用(yong)于(yu)傳輸﹑分配電能或傳送電信號。它與普通(tong)電線(xian)的差別主(zhu)要是電纜尺寸較大﹐結(jie)構較復雜。
5、直徑不同
直徑(jing)小的(de)叫(jiao)“線”;直徑(jing)大的(de)叫(jiao)“纜”。結構簡單的(de)叫(jiao)“線”;結構復雜的(de)叫(jiao)“纜”。
隨著使用范圍的擴大，很多品種“線中有纜”，“纜中有線”。所以沒有必要嚴格區分。在日常習慣上，人們把家用布電線叫做電線，把電力電纜簡稱電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)。電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)主要(yao)包(bao)括(kuo)裸電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)、繞組線(xian)(xian)(xian)、電(dian)(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)、通信電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)與光(guang)纜(lan)、電(dian)(dian)(dian)(dian)(dian)(dian)氣裝(zhuang)備用。廣義上(shang)，人(ren)們將電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)和(he)(he)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)統(tong)一(yi)稱為(wei)電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)。電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)和(he)(he)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)之間，沒(mei)有準確且固定的概念區(qu)分，一(yi)般僅以日(ri)常經(jing)驗來進行區(qu)分。在狹義上(shang)，分為(wei)電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)和(he)(he)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)，電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)和(he)(he)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)一(yi)般都是(shi)由(you)電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)導體(ti)、絕緣層和(he)(he)護(hu)套(tao)層三個(ge)部(bu)分組成。
