Home / What size support should be used for cable trays
The NEC requires that cable trays must be supported by members at an interval specified by the cable tray manufacturer, but not more than 5 feet for horizontal runs to support the weight of the cables and other loads. They are recommended for heavy cable runs as they provide good cable support as well as adequate ventilation. Wire Mesh Cable Trays are mainly used for telecommunication and fiber optic cables. The cable tray is made of a lightweight and easily rearrangeable design that can suit the various cable. A cable support system consists of cable support lengths and system components, such as cable support fittings, support elements, mounting elements and system acces-sories. For proper installation, design, and maintenance, adherence to international standards is essential. The mechanical and electrical characteristics, tests, certifications, overall quality management, recommendations mentioned in this technical guide only apply to our own cable management ranges and cannot under any circumstances be transposed to si osure, overheating or. Quality Type TC, Type PLTC, or Type ITC small diameter multi-conductor control and instrumentation cables will not be damaged due to the cable tray rung spacing.
