電(dian)線(xian)(xian)(xian)是(shi)指(zhi)傳輸(shu)電(dian)能的(de)導線(xian)(xian)(xian)。分裸(luo)線(xian)(xian)(xian)、電(dian)磁(ci)線(xian)(xian)(xian)和絕(jue)(jue)緣線(xian)(xian)(xian)。裸(luo)線(xian)(xian)(xian)沒有絕(jue)(jue)緣層，包(bao)括銅、鋁平線(xian)(xian)(xian)、架(jia)空絞線(xian)(xian)(xian)以及各種型(xing)材(如型(xing)線(xian)(xian)(xian)、母線(xian)(xian)(xian)、銅 排、鋁排等(deng))。它主要用于戶外架(jia)空及室內匯流 排和開關(guan)箱(xiang)。電(dian)磁(ci)線(xian)(xian)(xian)是(shi)通電(dian)后產(chan)(chan)生(sheng)(sheng)磁(ci)場(chang)或(huo)在磁(ci)場(chang)中(zhong)感(gan)應產(chan)(chan)生(sheng)(sheng)電(dian)流的(de)絕(jue)(jue)緣導線(xian)(xian)(xian)。

  它主要(yao)用(yong)于(yu)電(dian)動機(ji)和變壓器繞圈以及其(qi)他(ta)有關電(dian)磁設備。其(qi)導體主要(yao)是銅線，應(ying)有薄的(de)(de)絕緣層和良好的(de)(de)電(dian)氣機(ji)械性能，以及耐(nai)熱、防潮(chao)、耐(nai)溶劑(ji)等性能。選用(yong)不同的(de)(de)絕緣材(cai)料可獲(huo)得不同的(de)(de)特(te)性。
