一、适用范围 Application range

耐火电缆包罗含卤耐火电缆和无卤耐火电缆,两种耐火电缆均能在熄灭状况下在必然工夫(不小于1.5h)内不发作短路和断路毛病,确保持续供电以保持照明和传输旌旗灯号,保证人员有充足的工夫安全撤离,适用于防火要求较高的场合。

含卤耐火电缆可用于户外、职员密度较小的场合;无卤阻燃电缆熄灭时开释烟雾量小且无毒,更有利于火警状况下的职员分散,适用于高层建筑、剧院、病院、大型商场、车站、等主要的社会公共场合。

Fire resistant cable include ordinary and halogen free fire resistant cable. This cable has the following characteristics: Short circuit and open circuit failures are not to be expected in a certain period of time (not less than 1.5h) during direct flame burning, to secure continuous power supply of lighting and signals, to ensure sufficient time for evacuation. Due to low smoke halogen-free characteristics, as fire breaks out, with low smoke concentration and high visibility, the harmful gas is released at the least quantity to facilitate evacuation.Fewer cable combustion corrosive gases avoid the damage to the equipment and facilities. To meet the waterblocking requirements of rail transit,a radial waterblocking layer is put into the structure of cable.

This cable is mainly suitable for use in rail transit, stations,equipment installations, and also can be used in oil fields, power plants, chemical industry, hospitals, shopping malls, high-rise buildings, theaters and other high fireproof conditions,which is applied to AC rated voltage up to and including 0.6/1kv.
