Cable Trays are used to provide mechanical support in environments with a high volume of power control cables. These cables are designed to provide mechanical security as well as an ideal routing direction for power or control cables. These cables may be both above and below ground. There are several cable trays offered in a multitude of materials. Cable tray manufacturers use galvanised steel, aluminium, stainless steel, and glass fiber reinforced plastic to create cable trays. In addition to all this, the decision on which cable tray to use is entirely dependent on the usage and installation environment.
