電(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)纜的(de)區別電(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)線(xian)(xian)是由一根或幾(ji)根柔軟的(de)導(dao)線(xian)(xian)組成(cheng)，外面包(bao)以(yi)輕軟的(de)護(hu)(hu)層(ceng)，用于承載電(dian)(dian)(dian)(dian)流(liu)的(de)導(dao)電(dian)(dian)(dian)(dian)金屬(shu)線(xian)(xian)材。有(you)實心(xin)(xin)的(de)、絞合的(de)或箔片(pian)編織的(de)等各種形式。按絕(jue)緣狀況分為裸電(dian)(dian)(dian)(dian)線(xian)(xian)和絕(jue)緣電(dian)(dian)(dian)(dian)線(xian)(xian)兩(liang)大類(lei)。電(dian)(dian)(dian)(dian)纜由一根或多(duo)根相互絕(jue)緣的(de)導(dao)電(dian)(dian)(dian)(dian)線(xian)(xian)心(xin)(xin)置于密封護(hu)(hu)套(tao)中(zhong)構成(cheng)的(de)絕(jue)緣導(dao)線(xian)(xian)。其外可(ke)加(jia)保護(hu)(hu)覆(fu)(fu)蓋(gai)層(ceng)﹐用于傳(chuan)輸、分配電(dian)(dian)(dian)(dian)能或傳(chuan)送電(dian)(dian)(dian)(dian)信號。它與普通(tong)電(dian)(dian)(dian)(dian)線(xian)(xian)的(de)差別主要是電(dian)(dian)(dian)(dian)纜尺(chi)寸較大，電(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)纜多(duo)少錢，結構較復雜。電(dian)(dian)(dian)(dian)纜主要由導(dao)電(dian)(dian)(dian)(dian)線(xian)(xian)心(xin)(xin)、絕(jue)緣層(ceng)、密封護(hu)(hu)套(tao)以(yi)及保護(hu)(hu)覆(fu)(fu)蓋(gai)層(ceng)四個部分組成(cheng)。按其用途(tu)可(ke)分為電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)纜﹑通(tong)信電(dian)(dian)(dian)(dian)纜和控(kong)制(zhi)電(dian)(dian)(dian)(dian)纜等。
