Cable trays are mechanical support systems designed to route, protect, and organize cables in industrial, commercial, and utility installations . They are part of the broader cable management category and serve as alternatives to fully enclosed conduits or raceways. Cable trays can carry multiple types of cables, including:
Optical cables, also known as fiber optic cables, are primarily used for communication and data transmission. They can be installed in cable trays if they meet tray-rated standards defined by the National Electric Code (NEC), such as OFNP, OFCP, OFNR, OFCR, OFNG, OFCG, OFN, and OFC . These ratings ensure the cable's mechanical durability, flame resistance, and suitability for overhead or industrial tray applications.
Several types of tray are used in different applications. A solid-bottom tray provides the maximum protection to cables, but requires cutting the tray or using fittings to enter or exit cables. A deep, solid enclosure for cables is called a cable channel or cable trough. A ventilated tray has openings in the bottom of the tray, allowing some air circulation around the cables, water drainage, and allowing some dust to fall through the tray. Small cables may exit the tray throug
