Fireproof and fire-resistant plate trough cable tray is a high standard wiring profile for fire engineering. It is mainly composed of enclosed galvanized trough cable tray and embedded with composite fire-resistant plate, which combines the dual protection performance of fire and fire resistance. It is widely used in key fire protection scenarios such as high-rise buildings, underground pipe galleries, data rooms, and industrial plants, and is suitable for emergency power supply and communication line laying. The product is equipped with a sealed tank and reinforced refractory plate structure, which can effectively block open flames, high temperatures, and smoke infiltration, delay the spread of fire, continuously protect internal cables, and ensure stable operation of the circuit during a fire. The fire-resistant board has a tight and stable fit, is not easy to fall off or deform, and can resist high temperature erosion for a long time, making up for the protective shortcomings of ordinary fire-resistant bridge frames and adapting to strict fire construction standards. The bridge has a regular layout, complete specifications, strong installation adaptability, and is compatible with various standardized construction methods. The overall wiring is clean and orderly, making it easy for later inspection and maintenance as well as line expansion and renovation. With solid fire resistance protection capabilities and stable engineering adaptability, it has become a commonly used supporting profile for high-end firefighting electromechanical projects.
