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)(dian)(dian)線(xian)(xian)(xian)(xian)是指傳輸電(dian)(dian)(dian)(dian)(dian)能的(de)(de)導線(xian)(xian)(xian)(xian)。分裸線(xian)(xian)(xian)(xian)、電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)線(xian)(xian)(xian)(xian)和絕(jue)(jue)(jue)緣(yuan)線(xian)(xian)(xian)(xian)。裸線(xian)(xian)(xian)(xian)沒有(you)絕(jue)(jue)(jue)緣(yuan)層，包(bao)括銅、鋁(lv)平(ping)線(xian)(xian)(xian)(xian)、架空(kong)絞線(xian)(xian)(xian)(xian)以(yi)及各種型(xing)材(cai)(如(ru)型(xing)線(xian)(xian)(xian)(xian)、母線(xian)(xian)(xian)(xian)、銅 排(pai)(pai)、鋁(lv)排(pai)(pai)等(deng))。它主要用于(yu)戶外架空(kong)及室內匯流 排(pai)(pai)和開關箱。電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)線(xian)(xian)(xian)(xian)是通電(dian)(dian)(dian)(dian)(dian)后產(chan)生(sheng)磁(ci)(ci)場(chang)或(huo)在磁(ci)(ci)場(chang)中(zhong)感應產(chan)生(sheng)電(dian)(dian)(dian)(dian)(dian)流的(de)(de)絕(jue)(jue)(jue)緣(yuan)導線(xian)(xian)(xian)(xian)。它主要用于(yu)電(dian)(dian)(dian)(dian)(dian)動機(ji)和變壓器(qi)繞(rao)圈以(yi)及其他(ta)有(you)關電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)設備。其導體(ti)主要是銅線(xian)(xian)(xian)(xian)，應有(you)薄的(de)(de)絕(jue)(jue)(jue)緣(yuan)層和良好的(de)(de)電(dian)(dian)(dian)(dian)(dian)氣機(ji)械性(xing)(xing)能，以(yi)及耐熱、防潮、耐溶(rong)劑等(deng)性(xing)(xing)能。選用不(bu)同的(de)(de)絕(jue)(jue)(jue)緣(yuan)材(cai)料可獲(huo)得不(bu)同的(de)(de)特性(xing)(xing)。
