The fireproof cable tray with fireproof board is an upgraded fire-fighting wiring matching profile. It is equipped with special fireproof partitions and lining plates on the basis of the traditional tray structure, and the overall insulation and flame retardant layer is more complete. It is suitable for various building electromechanical, underground pipe gallery, factory power distribution and public building engineering projects with strict fire protection requirements. The built-in fireproof board has good insulation, fire and smoke blocking effects, which can effectively isolate high-temperature heat sources, slow down the spread of fire, avoid damage to internal cables by open flames and high-temperature smoke, and ensure the continuous operation of emergency power and communication lines during fire situations. The board is tightly adhered, structurally stable, and not easily detached or cracked. It has stable long-term performance and is suitable for various indoor enclosed wiring environments. This type of cable tray is easy to install, suitable for conventional lifting and wall installation construction methods, with neat and orderly wiring, making it convenient for later line maintenance and renovation. Solid fire-resistant structural design can effectively improve the fire safety level of electrical systems and is the preferred wiring profile for high standard fire mechanical and electrical engineering.
