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級規范(在950℃～1000℃火焰中燃燒90分鐘，3A保險絲不熔斷)，也可經過英國BS6387的CWZ很好級別檢驗(C---在950℃火焰中燃燒3小時；W---水噴淋；Z---驚動)。燃燒后的煙氣---低煙、無鹵、無磷氮、無重金屬、無毒、無害，煙氣毒性級別到達高分子資料的級別ZA1級(實驗動物在30分鐘染毒期內及以后3天內不死亡且平均體重康復)，對人不會形成二次傷害。作為用戶，作為設計師，可能會選擇礦物質絕緣電纜BTTZ，由于他們垂青的是BTTZ有統一的國度標準，性能保證，牢靠，質量好控制，不用承當義務。還有一局部用戶和設計師會選擇柔性礦物質絕緣電纜，那是由于他們風聞BTTZ礦物質絕緣電纜硬，欠好安裝，長度短，需求運用銜接器，人工本錢高。柔性礦物質絕緣電纜的本錢低，不用接頭，安裝便利。可是事實上真的是這樣嗎。

有人(ren)說(shuo)它硬欠好安(an)裝(zhuang)，從國度標準可知(zhi)。BTTZ電纜的安(an)裝(zhuang)半徑為不(bu)小(xiao)于電纜外(wai)徑的2-6倍，遠小(xiao)于柔性系列不(bu)小(xiao)于15-20倍的請求(qiu)。

有(you)人說它長(chang)度短，截面越大電(dian)(dian)(dian)(dian)(dian)纜越短。我(wo)國(guo)的(de)(de)(de)(de)首代和次代生設(she)備和工藝的(de)(de)(de)(de)確無(wu)法打長(chang)度出產(chan)。但自2009年以來，我(wo)國(guo)曾(ceng)(ceng)經(jing)有(you)了(le)第三代BTTZ礦(kuang)物質絕緣(yuan)電(dian)(dian)(dian)(dian)(dian)纜出產(chan)技藝（主動灌裝工藝），出產(chan)長(chang)度早已(yi)不再(zai)受限(xian)，并且產(chan)品(pin)曾(ceng)(ceng)經(jing)在國(guo)內各種項(xiang)目上得(de)到普遍運用(yong)，產(chan)品(pin)的(de)(de)(de)(de)技藝應(ying)用(yong)曾(ceng)(ceng)經(jing)非(fei)常干練。就詳細差別(bie)上，電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)，普通(tong)是(shi)指由(you)單根(gen)(gen)(gen)或(huo)多(duo)跟銅(tong)或(huo)鋁等(deng)導(dao)(dao)(dao)(dao)體(ti)(ti)絞合而成，然后在電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜導(dao)(dao)(dao)(dao)體(ti)(ti)外(wai)(wai)部加上絕緣(yuan)層(ceng)(ceng)或(huo)護(hu)套層(ceng)(ceng)而組(zu)成的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜種類。電(dian)(dian)(dian)(dian)(dian)纜普通(tong)是(shi)由(you)一(yi)根(gen)(gen)(gen)或(huo)多(duo)根(gen)(gen)(gen)導(dao)(dao)(dao)(dao)體(ti)(ti)組(zu)成，而電(dian)(dian)(dian)(dian)(dian)纜的(de)(de)(de)(de)每(mei)一(yi)根(gen)(gen)(gen)導(dao)(dao)(dao)(dao)體(ti)(ti)，又(you)是(shi)由(you)一(yi)股(gu)(gu)(gu)或(huo)多(duo)股(gu)(gu)(gu)導(dao)(dao)(dao)(dao)體(ti)(ti)絞合而成，再(zai)外(wai)(wai)包絕緣(yuan)或(huo)護(hu)套構成，簡單點(dian)說，電(dian)(dian)(dian)(dian)(dian)纜的(de)(de)(de)(de)每(mei)一(yi)根(gen)(gen)(gen)導(dao)(dao)(dao)(dao)體(ti)(ti)都(dou)能夠算(suan)作一(yi)股(gu)(gu)(gu)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)。這是(shi)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)和電(dian)(dian)(dian)(dian)(dian)纜直接的(de)(de)(de)(de)差別(bie)。1、電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)：是(shi)由(you)一(yi)根(gen)(gen)(gen)或(huo)幾根(gen)(gen)(gen)柔軟(ruan)(ruan)的(de)(de)(de)(de)導(dao)(dao)(dao)(dao)線(xian)(xian)(xian)(xian)組(zu)成，外(wai)(wai)面包以輕軟(ruan)(ruan)的(de)(de)(de)(de)護(hu)層(ceng)(ceng)，用(yong)于承載(zai)電(dian)(dian)(dian)(dian)(dian)流的(de)(de)(de)(de)導(dao)(dao)(dao)(dao)電(dian)(dian)(dian)(dian)(dian)金屬線(xian)(xian)(xian)(xian)材。有(you)實心的(de)(de)(de)(de)﹑絞合的(de)(de)(de)(de)或(huo)箔片編織(zhi)的(de)(de)(de)(de)等(deng)各種方式。
