東北防火電纜運用本產品出產的防火耐火電線電纜，耐火等級可到達GB12666.6的A級標準(在950℃～1000℃火焰中燃燒90分鐘，3A保險絲不熔斷)，也可通過英國BS6387的CWZ很好等級檢驗(C---在950℃火焰中燃燒3小時；W---水噴淋；Z---轟動)。燃燒后的煙氣---低煙、無鹵、無磷氮、無重金屬、無毒、無害，煙氣毒性全等級到達高分子材料的安等級ZA1級(實驗動物在30分鐘染毒期內及今后3天內不逝世且均勻體重恢復)，對人不會形成二次損傷。

東北防火電纜中屏蔽線的作用是將電磁場噪聲源與活絡設備隔離開，并堵截噪聲源的傳播途徑。屏蔽分為有源屏蔽和無源屏蔽。自動屏蔽的目的是避免噪聲源向外輻射，該輻射源正在屏蔽噪聲源。被迫屏蔽的目的是避免活絡設備遭到噪聲源的干擾并屏蔽活絡設備。

電(dian)線和電(dian)纜的外(wai)層(ceng)(ceng)通常是橡膠(jiao)或橡膠(jiao)復合材料套管。該(gai)層(ceng)(ceng)用于絕緣(yuan)，還可以保(bao)護電(dian)纜免受損壞。屏(ping)蔽層是(shi)帶有(you)金屬織造外殼的(de)電(dian)線(xian)，專門規劃用(yong)于削(xue)減(jian)外部(bu)電(dian)磁(ci)場對電(dian)源(yuan)或通信線(xian)路(lu)的(de)影(ying)響。該屏(ping)蔽線(xian)還具有(you)避免線(xian)路(lu)向外輻(fu)射電(dian)磁(ci)能的(de)作用(yong)。

屏蔽層需(xu)求(qiu)接地(di)，外部干擾信號可以(yi)通過該層引入大地(di)，避免(mian)干擾信號進入內部導體的(de)(de)(de)(de)干擾，削減傳輸信號的(de)(de)(de)(de)損耗。電(dian)纜(lan)分(fen)為高(gao)壓電(dian)纜(lan)或(huo)低壓電(dian)纜(lan)。如果是高(gao)壓，內部將有一(yi)層樹脂狀(zhuang)的(de)(de)(de)(de)填料(liao)，用于絕緣。在高(gao)壓電(dian)纜(lan)中，這(zhe)一(yi)層是絕緣的(de)(de)(de)(de)重要部分(fen)。低壓下沒有這(zhe)樣的(de)(de)(de)(de)東(dong)西。然后，將包裹一(yi)條類似帶子的(de)(de)(de)(de)東(dong)西，以(yi)便固定電(dian)纜(lan)的(de)(de)(de)(de)每個芯(xin)線(xian)并填充心(xin)的(de)(de)(de)(de)空(kong)地(di)。
