Basic knowledge of fire protection bridge!

Fire-resistant cable trays are primarily constructed of fireproof panels made of glass fiber reinforced material and inorganic adhesives, combined with a metal frame and other fire-resistant substrates. A fire-retardant coating is applied to the exterior, preventing the fire from spreading. Fire-resistant cable trays offer excellent fire protection and flame retardancy. They are also fire-resistant, oil-resistant, corrosion-resistant, non-toxic, and non-polluting. They are easy to install, structurally sound, and offer a long service life. They are also aesthetically pleasing. Cables installed in cable trays maintain a clean and easy-to-clean environment. The fire-retardant coating features a thin coating, high fire resistance, and strong adhesion.

Fire-resistant cable trays are constructed by spraying a layer of fire-retardant paint onto ordinary cable trays to provide a fire-resistant and flame-retardant effect. In reality, the cable tray itself won't catch fire; it's the cables that could catch fire. This is due to the fire-retardant coating's effectiveness.

Fire-resistant cable trays, with a matte finish, are generally used for power distribution lines for firefighting equipment, including fire control rooms, fire pumps, fire elevators, smoke exhaust fans, and automatic fire alarm systems. Fire-resistant cables can be used for other power distribution lines, eliminating the need for fire-resistant cable trays. Fire-resistant cable trays in underground garages are required to withstand fires for at least one hour.

For sections requiring fire-resistant cable trays, fire-resistant or flame-retardant panels or mesh materials can be added to pallets and ladders to create closed or semi-enclosed structures. The cable trays should be coated with a fire-resistant coating that complies with CECS 24;90, "Technical Specifications for the Application of Fire-Retardant Coatings for Steel Structures." The overall fire resistance should meet the requirements of relevant national codes and standards.
