電線電纜的區別

電線

電(dian)線(xian)(xian)(xian)是(shi)由一根(gen)或幾根(gen)柔軟的(de)導線(xian)(xian)(xian)組成，外面包以輕軟的(de)護層，用于(yu)承載電(dian)流的(de)導電(dian)金屬(shu)線(xian)(xian)(xian)材。有實心的(de)、絞合的(de)或箔片編(bian)織的(de)等各種(zhong)形(xing)式。按絕緣(yuan)狀(zhuang)況(kuang)分為裸電(dian)線(xian)(xian)(xian)和絕緣(yuan)電(dian)線(xian)(xian)(xian)兩大(da)類。

電纜

由一根或多根相(xiang)互絕緣的導(dao)電(dian)(dian)(dian)(dian)線心置于密(mi)封護(hu)套中構成(cheng)的絕緣導(dao)線。其(qi)外可加保(bao)(bao)護(hu)覆(fu)蓋層(ceng)﹐用于傳輸、分(fen)(fen)配電(dian)(dian)(dian)(dian)能(neng)或傳送電(dian)(dian)(dian)(dian)信(xin)號(hao)。它與普通電(dian)(dian)(dian)(dian)線的差別主(zhu)要是電(dian)(dian)(dian)(dian)纜(lan)尺寸較(jiao)大，結構較(jiao)復(fu)雜。電(dian)(dian)(dian)(dian)纜(lan)主(zhu)要由導(dao)電(dian)(dian)(dian)(dian)線心、絕緣層(ceng)、密(mi)封護(hu)套以(yi)及保(bao)(bao)護(hu)覆(fu)蓋層(ceng)四(si)個部分(fen)(fen)組成(cheng)。按其(qi)用途可分(fen)(fen)為電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)纜(lan)﹑通信(xin)電(dian)(dian)(dian)(dian)纜(lan)和控制電(dian)(dian)(dian)(dian)纜(lan)等。

Tips：用(yong)于電(dian)路裝(zhuang)修的線(xian)材我(wo)們通常統稱(cheng)為電(dian)線(xian)電(dian)纜(lan)(lan)，電(dian)線(xian)和電(dian)纜(lan)(lan)并沒有嚴格的界限。家裝(zhuang)中一般(ban)不需用(yong)到電(dian)纜(lan)(lan)，電(dian)線(xian)就滿足要求。
