适用范围
Applications
本产品适用于交流额定电压0.6/1KV及以下聚氯乙烯绝缘耐火电缆，要求电缆在着火情况下仍能保持一定时间继续运行的固定敷设场合。主要用于高层建筑、地下铁路、核电站及重要工矿企业与防火安全和消防救生的地方，如应急电源、户内消防设备、火灾报警设备、信号灯、通风排烟设备、紧急用电梯等的供电线路。能有效地起到消防救生的目的，且由于电缆本身不会造成火灾，可减少火灾发生的频率及危害。
The product is used under 0.6/1KV,ａnd can work properly for certain period of time even in fire.It is mainly used in high buildings,subways,nuclear station as well as safety devices,such as emergency power supply,fire-fighting equipment,fire alarming lights,elevator power lines.The cable will not burn even in the fire.
