Fire-resistant power cable is a special cable that can maintain the power transmission function in case of fire. It is mainly used in places with high fire protection requirements, such as high-rise buildings, subways, tunnels, etc., to ensure that the power system can continue to supply power in the event of a fire.
Fire-resistant power cables have the following characteristics:
1. High temperature resistance: fire-resistant cable can maintain stable electrical performance in high temperature environment, is not easy to melt and burn, and can continue to transmit electrical energy in the case of fire.
2. Flame retardant performance: The outer sheath material of the fire-resistant cable has good flame retardant performance, which can self-extinguish in the case of fire and prevent the spread of flame, reducing the impact of fire on the power system.
3. Fire resistance: The insulation material of the fire-resistant cable has good fire resistance, which can maintain the insulation performance of the cable in the case of fire and prevent short circuit or leakage of the power system.
4. Corrosion resistance: The outer sheath material of the refractory cable has good corrosion resistance, which can work stably in a certain chemical environment and extend the service life of the cable.
Fire-resistant power cables are widely used in high-rise buildings, subways, tunnels and other places with high fire protection requirements. It can maintain the normal operation of the power system in the case of fire, ensuring the safety of personnel and the protection of property. At the same time, the installation and maintenance of fire-resistant power cables are also relatively simple and easy to use.
