The Application of Control Cable:
It is used in the environment with high demand on fire-resisting performance such as high-rise buildings, oil field, power station, power plant, mine, chemical industry and subway. It is also the necessary cable prepared for emergency power, fire pump and communication system of elevator. It has good flame-resistant. In time of being directly fire by flame, it could ensure continual power supply and signal transmission to keep lightening in certain time for people to retreat safely and also to benefit fighting fire to reduce damage
