Special Cable For Fire Resistant System
本产品适用于0.6/1kv及以下的高层建筑物、地铁、隧道、剧场、人防工程、石化系统等所作输配电线路或火灾报警设备、通信设备等应急设施的供电线路及信号控制线路。电缆除低烟无卤高阻燃特性外，还应能处在火焰燃烧中正常运行180min，当火灾发生时，不发生短路和断路故障，一直保障电力供给，维持系统运行。并且燃烧时烟雾透光率高、毒性低，从而显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.
