Fire-resistant cable tray

Fireproof Cable Tray:

The fireproof cable tray features a steel outer shell, double-layer fireproof covers, and an internal inorganic fireproof trough box. The average thickness of the insulation layer is 25mm. The double-layer covers facilitate ventilation and heat dissipation, while the interior is sprayed with fireproof coating. In the event of a fire, the coating expands, blocking the heat dissipation holes and protecting the cables inside the trough box. The inorganic fireproof trough box has undergone a 60-minute fire resistance test by the Fixed Fire Resistance Testing Center, with no damage to the cables. The supporting structure is robust, effectively securing the inorganic fireproof trough box.

Application of Fireproof Cable Tray: Suitable for power cables below 10KV, as well as control cables, lighting wiring, and other indoor and outdoor overhead cable trenches and tunnel installations. The fireproof tray is primarily composed of glass fiber reinforced materials, inorganic adhesive composite fireproof boards, metal framework composites, and other fireproof base materials, with an outer layer of fireproof coating. The fireproof tray does not burn when exposed to fire, thereby preventing the spread of flames. It offers excellent fire resistance and flame-retardant effects, along with properties such as high temperature resistance, oil resistance, corrosion resistance, non-toxicity, and pollution-free characteristics. It is also easy to install as a whole. The fireproof coating features a thin layer, high fire resistance limit, and strong adhesion.

Advantages of Trough-Type Fireproof Cable Tray

1. Traditional metal cable trays have a thin surface anti-corrosion layer, which is prone to damage during transportation and installation. Additionally, the surface contains micro-pores, allowing corrosive gases to penetrate the structural layer and compromise the anti-corrosion effect.

2. Non-metal cable trays offer strong anti-corrosion performance but lack mechanical strength. To address these issues, our company has developed a composite epoxy resin fiberglass cable tray: It incorporates a metal framework within the composite epoxy resin cable tray, retaining the original characteristics of the composite epoxy resin tray while enhancing mechanical strength. This allows it to support large-diameter cables, with a span of up to 15 meters.

3. To resolve the delamination issue caused by the different expansion coefficients of metal and non-metal materials, a bonding layer is added between the metal and non-metal components.

4. To address problems such as easy powdering and aging, a protective layer with special functions like light resistance is molded onto the surface of the tray.

5. The composite epoxy resin cable tray has been certified by authoritative institutions to have a service life of over 30 years. This product has been in use for 15 years without any signs of fading or aging.
