There are several types of cable trays:
The tray type cable tray has the advantages of light weight, large load, beautiful appearance, simple structure and convenient installation. Applicable to petroleum, chemical, light industry, telecommunications and other aspects. The surface treatment of the tray cable bridge is galvanized and painted. If it is in a heavy corrosive environment, it can be treated with special anti-corrosion treatment. The maximum allowable uniform load and variable of the tray cable tray under different spans.
The trough cable tray is a fully enclosed cable tray suitable for communication cables, thermocouple cables and other high-sensitivity system control cables. It has a good effect on the shielding interference of the control and the protection of the environmental cable in the medium corrosion.
Cascade cable trays are used for the laying of general straight and light cables, especially for the laying of high and low power cables.
FRP cable trays, made of glass fiber reinforced plastic and flame retardant and other materials, is fire-resistant and self-extinguishing, and has high corrosion resistance. It is used in strong corrosive environments such as chemical, metallurgical and petroleum.
Cable tray advantages:
The cable tray is the full name of a rigid structural system with a tightly supported cable consisting of a straight section of a pallet or ladder frame, a bend, a component, and a support arm (arm bracket), a hanger, and the like. It is a metal frame of a wire slot type that is placed along with the pipe gallery. The cable bridge factory has the characteristics of full variety, wide application, high strength, light structure, low cost, simple construction, flexible wiring, installation standard and beautiful appearance.
The cable bridge has high mechanical strength. It has the rigidity of the metal bridge and the toughness of the glass steel bridge. It has good corrosion resistance, strong anti-aging performance, beautiful appearance, convenient installation and long service life.
