In the engineering design documents, the general fireproof cable tray is usually called the cable tray, without specifying the specific structural characteristics. Different types and production materials have great differences in the price of the fireproof cable enclosure structure, and the confusion of the structural types will bring heat dissipation, mechanical protection and other problems to the work site. Therefore, in the design phase, the designer shall be required to reasonably select the structural characteristics of the fireproof cable tray according to the environmental characteristics and technical requirements of the project, and clearly indicate them in the type label and material list of the layout plan.
2. Selection of fireproof cable tray materials
The material of fireproof cable tray is another common problem in the engineering design of fireproof cable tray. According to the classification of materials, there are mainly steel, glass fiber reinforced plastic and aluminum alloy fireproof cable trays. FRP fire-proof trough cable tray is light in weight, and its proportion is only 1/4 of that of carbon steel; Good water resistance and corrosion resistance, suitable for chemical plants.
3. Type selection of anti-corrosion coating on the surface of fireproof cable tray
The third common problem in engineering design is that the type of fireproof cable tray is not marked with anti-corrosion coating category, and there is no unified text description. There are lessons from this problem in reality. For example, China undertook a general contracting project in Indonesia. The surface corrosion treatment of steel fire-proof cable tray did not undergo salt spray test, and the cable tray was severely rusted soon after completion and had to be replaced.
Our cable trays are ISO and CE certified. Our products are made of mild steel, pre galvanized steel, hot-dip galvanized steel, stainless steel, aluminum, polymer alloy, FRP or GRP (fiber reinforced plastic), PVC. All products comply with IEC and NEMA standards.
Cable tray width: 50mm – 1200mm
Cable tray height: 25mm – 300mm
Length of cable tray: 2m - 6m
If necessary, we can provide a complete version of the cable tray catalog and complete accessories.
