Use of fire-resistant cable tray
The fireproof cable tray is made of steel shell, double-layer fireproof cover, and built-in inorganic fireproof box. The average thickness of the insulation layer is 25mm, the double-layer cover is ventilated and dissipated, and the fireproof paint is sprayed inside. When the fireproof cable tray encounters fire, the paint expands and blocks. The heat dissipation hole protects the cables in the tank. The fire performance of the inorganic fireproof tank has passed the 60-minute fire resistance test of the National Fixed Fire Resistance Test Center, and the cable is not damaged. The structure of the support is good, and the inorganic fireproof tank can be effectively fixed.
Fireproof cable tray application: suitable for laying of power cables below 10KV, as well as control cables, lighting wiring and other indoor and outdoor overhead cable trenches and tunnels. The fireproof bridge is mainly composed of glass fiber reinforced material, fireproof board composited with inorganic adhesive, composite with metal skeleton and other fireproof substrates, and the outer layer is coated with fireproof coating. The fire bridge will not burn in case of fire, thus preventing the spread of the fire. The fire bridge has extremely good fire resistance and fire resistance, and has the characteristics of fire resistance, oil resistance, corrosion resistance, non-toxicity, non-polluting, and convenient overall installation. Fire retardant coatings have the characteristics of thin coating, high fire resistance and strong adhesion.

Advantages of trough fireproof cable tray
1. The thickness of the anti-corrosion layer on the surface of the traditional metal bridge is small, which is easy to be damaged during transportation and installation, and there are tiny holes on the surface, through which corrosive gas can easily enter the structural layer and affect the anti-corrosion effect;
Second, the non-metallic cable tray has strong anti-corrosion performance, but the mechanical strength is not enough. Based on these circumstances, our company has developed a composite epoxy resin composite fiberglass cable tray: it adds a metal frame to the composite epoxy resin cable tray, which not only retains the characteristics of the original composite epoxy resin cable tray, but also increases the mechanical Strength, can carry large diameter cables, bridge spans up to 15 meters.
3. In order to solve the delamination problem caused by different expansion coefficients of metals and non-metals, a bonding layer is added between the metal and the non-metal;
Fourth, in order to solve the problems of easy powdering and aging, a protective layer with special effects such as anti-light is molded on the surface of the bridge;
5. The composite epoxy resin composite cable bridge has a service life of more than 30 years identified by authoritative institutions. This product has been used for 15 years, and there is no sign of fading and aging.
6. The FRP cable tray includes the main body of the bridge and the cover of the bridge, both of which are layered structures, and the layers are tightly combined into one by molding. , fire protection layer, anti-corrosion layer, protective layer.
