Fireproof coating system for electrical cables and pipelines
When a fire occurs, certain important fire-fighting facilities, such as smoke exhaust fans, fire elevators, fire alarm systems and emergency lighting systems, need to maintain continuous power supply to ensure their normal operation and to fulfill their intended functions. Therefore, the power cables for these fire-fighting facilities must adopt necessary fire protection measures.
Application
Suitable for environments in buildings that are vulnerable to fire attacks and require special protection for electrical wires and cables.
The electrical wire and cable fireproof coating system ensures that certain important fire-fighting facilities, such as smoke exhaust fans, fire elevators, fire alarm systems and emergency lighting systems, can maintain continuous power supply to ensure their normal operation and fulfill their intended functions during a fire.
