ZR是阻燃型

IV是4級
B是B類

BV是PVC絕緣電線

總稱：阻燃型4級B類PVC絕緣電線

  電(dian)(dian)(dian)線(xian)(xian)是(shi)指傳輸(shu)電(dian)(dian)(dian)能(neng)(neng)的(de)(de)導(dao)(dao)線(xian)(xian)。分裸(luo)(luo)線(xian)(xian)、電(dian)(dian)(dian)磁(ci)(ci)線(xian)(xian)和(he)(he)絕緣線(xian)(xian)。裸(luo)(luo)線(xian)(xian)沒有絕緣層(ceng)，包括銅(tong)、鋁(lv)平線(xian)(xian)、架空絞線(xian)(xian)以(yi)及(ji)各種(zhong)型材(如型線(xian)(xian)、母線(xian)(xian)、銅(tong) 排、鋁(lv)排等)。它(ta)主(zhu)(zhu)要用(yong)于(yu)戶外架空及(ji)室內匯流(liu)(liu) 排和(he)(he)開關箱。電(dian)(dian)(dian)磁(ci)(ci)線(xian)(xian)是(shi)通電(dian)(dian)(dian)后產生磁(ci)(ci)場或在(zai)磁(ci)(ci)場中感應(ying)產生電(dian)(dian)(dian)流(liu)(liu)的(de)(de)絕緣導(dao)(dao)線(xian)(xian)。它(ta)主(zhu)(zhu)要用(yong)于(yu)電(dian)(dian)(dian)動機(ji)和(he)(he)變壓(ya)器繞圈以(yi)及(ji)其他有關電(dian)(dian)(dian)磁(ci)(ci)設備。其導(dao)(dao)體主(zhu)(zhu)要是(shi)銅(tong)線(xian)(xian)，應(ying)有薄(bo)的(de)(de)絕緣層(ceng)和(he)(he)良好(hao)的(de)(de)電(dian)(dian)(dian)氣機(ji)械性能(neng)(neng)，以(yi)及(ji)耐熱(re)、防潮、耐溶劑等性能(neng)(neng)。選用(yong)不(bu)同的(de)(de)絕緣材料(liao)可獲(huo)得不(bu)同的(de)(de)特性。
