耐火電纜
名稱(chēng):
ZHT-FRVV防火系統(tǒng)專(zhuān)用電纜
說(shuō)明:
防火系統(tǒng)專(zhuān)用電纜
SpecialCableForFireResistantSystem
本產(chǎn)品適用于0.6/1kv及以下的高層建筑物、地鐵、隧道、劇場(chǎng)、人防工程、石化系統(tǒng)等所作輸配電線路或火災(zāi)報(bào)警設(shè)備、通信設(shè)備等應(yīng)急設(shè)施的供電線路及信號(hào)控制線路。電纜除低煙無(wú)鹵高阻燃特性外，還應(yīng)能處在火焰燃燒中正常運(yùn)行180min，當(dāng)火災(zāi)發(fā)生時(shí)，不發(fā)生短路和斷路故障，一直保障電力供給，維持系統(tǒng)運(yùn)行。并且燃燒時(shí)煙霧透光率高、毒性低，從而顯示其防火安全和消防救生的功能。
