用于高层建筑，地铁，电站及一些重要场所等；具有防火特性的环境场合，除了在0.6/1KV额定工作电压下传送电力外； 耐火电缆还可在 Refractory cables are used in high-rise buildings, subways, power stations and some important places, etc .; environmental conditions with fire resistance, in addition to transmitting power at the rated working voltage of 0.6 / 1KV; refractory cables can also be used in
Safe operation for a certain period of time under burning conditions,
的使用安全系数、为救助火灾赢得了一定时间； 950-1000 degrees Celsius high-temperature flames keep safe operation for 3 hours, which greatly improves the safety factor of the use of refractory cables and wins a certain time for fire rescue;
In subways, power stations, office buildings, and public places, in order to reduce the fire accidents caused by the heating and burning of cables, the current flame retardant cables are mainly halogen flame retardant. When a fire occurs, a large amount of smoke will be generated, which will be toxic and stimulate
And corrosive hydrogen halide gas, smoke will hinder
For fire fighting and evacuation, hydrogen halide gas will corrode equipment and endanger human health, and production and use of halogen-free flame-retardant cables have become a trend;
Petrochemical, steel, aerospace, shipbuilding, military, pharmaceutical, food, plastic machinery, boiler and other industries related to heat and high temperature all need wires and cables that can withstand a certain high temperature.
