Fire-resistant bridgeways are suitable for power cables below 10KV, as well as control cables, lighting wiring, and overhead cable conduits in both indoor and outdoor cable tunnels.
Fire-resistant bridge supports are composed of fire-resistant boards made by combining glass fiber reinforced materials and inorganic binders, which are then bonded with metal frames, as well as other fire-resistant materials. They are coated with fire-resistant paint, ensuring that the bridge supports do not burn when exposed to fire, effectively preventing the spread of flames. They offer excellent fire-retardant properties, are resistant to heat, oil, corrosion, non-toxic, and environmentally friendly. The overall installation is convenient, the structure is rational, the service life is long, and they are aesthetically pleasing. Cables are installed in the cable bridge supports, resulting in a clean environment and easy cleaning. The fire-resistant paint features thin coatings, high耐火性, and strong adhesion.

Fire-resistant bridge supports are coated with a fire-retardant paint on the surface of the standard bridge supports to prevent fire and retard combustion. In reality, the bridge supports themselves do not catch fire; it is only the cables that can ignite, and the fire-retardant paint's role in preventing fire and combustion.
Fire-resistant bridge supports with a matte finish, commonly used in fire protection equipment power distribution lines, including fire control rooms, fire pumps, fire elevators, smoke and exhaust fans, and automatic fire alarm systems. For power distribution lines other than the automatic fire alarm system, fire-resistant cables can be used instead of fire-resistant bridge supports. Fire-resistant bridge supports in underground parking garages must have a fire resistance time of over 1 hour. For sections requiring fire-resistant bridge supports, fire-resistant or flame-retardant boards and mesh materials can be added to trays and ladder racks to form a sealed or semi-enclosed structure. Additionally, a fire-resistant coating in accordance with CECS 24; 90 "Technical Specification for the Application of Fire-Resistant Coatings on Steel Structures" should be applied to the bridge supports' surface, with the overall fire resistance meeting national regulations and standards.
