ZHT-FRVV防火系統(tǒng)專用電纜
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。
    It can be used not only to transmit and distribute power on the power line of 0.6/1kv voltage or below for high-rise building, subway, tunnel, theater, civil air defense engineering, petrochemical system, but also as power supply wire and signal control circuit of emergency facilities such as power transmission and distribution systems, fire alarm equipment and communications equipment and so on. Besides of features of LSZH and high flame resistance, it can also normally operate within 180min under the condition of flame burning. When the fire occurs, short-circuit and open circuit faults would not happen. It could endure continually supplying power and maintain the normal operation of system. During the process of burning, high light transmittance and low toxicity of cable can be considered as an evidence of functions of fireproofing safety and fire rescue.
