耐火(huo)電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜(lan)是指在電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜(lan)火(huo)災(zai)事故中，該電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜(lan)產品能夠(gou)在外部火(huo)焰依(yi)然燃(ran)燒的情況下，能夠(gou)堅持(chi)一定時間的正常(chang)運作，保(bao)(bao)持(chi)電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜(lan)線(xian)(xian)(xian)路(lu)完整性并保(bao)(bao)持(chi)線(xian)(xian)(xian)路(lu)設備(bei)的正常(chang)運轉。

耐火電纜型號表示：N

耐火鎧裝電纜型號

 耐火(huo)控制(zhi)鎧裝電(dian)纜型(xing)號：NH-KVV22、NH-KVV32、NH-KVVR22

耐火鎧裝電力電纜型號(hao)：NH-YJV22、NH-VV22，NH-YJV32

YJV22鎧裝(zhuang)電(dian)(dian)力電(dian)(dian)纜(lan)

耐火鎧裝屏蔽控制電纜型(xing)號：NH-KVVP-22、NH-RVVP-22、NH-KVVRP-22、NH-KVVP2-22

鎧裝電纜型號表示法

22——雙(shuang)鋼帶繞包(bao)鎧裝聚氯乙烯(xi)護套、23——雙(shuang)鋼帶繞包(bao)鎧裝聚乙烯(xi)護套

32——細圓(yuan)鋼絲鎧(kai)裝(zhuang)聚氯乙烯護、33——細圓(yuan)鋼絲鎧(kai)裝(zhuang)聚乙烯護套

42——粗圓鋼絲(si)鎧裝聚氯乙烯(xi)護套、43——粗圓鋼絲(si)鎧裝聚乙烯(xi)護套

耐火電(dian)纜中還有一(yi)種(zhong)特(te)殊的特(te)種(zhong)電(dian)纜，稱(cheng)為(wei)防火電(dian)線(xian)電(dian)纜。它是以(yi)(yi)無(wu)縫(feng)銅管作為(wei)護(hu)套，以(yi)(yi)氧化鎂做為(wei)絕緣材料制造而成(cheng)。因其材料的特(te)殊性，防火電(dian)線(xian)電(dian)纜既(ji)不(bu)(bu)燃(ran)燒，也不(bu)(bu)延燃(ran)。經實驗表明：在(zai)800～900℃中2小時，防火電(dian)線(xian)電(dian)纜依然(ran)正常運作，在(zai)1000℃下30分鐘內依然(ran)持續正常運轉。
