Cable Trays

Cable trays support cable the way that roadway bridges prop up traffic. A bridge is a structure that provides safe passage for traffic across open spans. Cable tray is the bridge that allows for safe transport of wires across open span. Therefore, think of cable tray as the structural ingredient of a building’s electrical system. In the electrical wiring of buildings, a cable tray system is used to support insulated electric cables used for power allocation and communication. Cable trays are used as an alternative to open wiring or electrical conduit systems, and are commonly used for cable administration in profitable and industrial construction. They are especially useful in situations where changes to a wiring system are predictable, since new cables can be installed by laying them in the tray, instead of pulling them through a pipe. Several types of tray are used in different applications. A solid-bottom tray provides the maximum fortification to cables, but requires cutting the tray or using furnishings to enter or exit cables. A deep, solid inclusion for cables is called a cable channel or cable ditch. Large power cables laid in the tray may require support blocks to preserve spacing between conductors, to prevent overheating of the wires. Smaller cables may be laid unsecured in straight trays, or secured with cable ties to the bottom of upright mounted trays. Common cable trays are made of galvanize steel, stainless steel, aluminum, or glass-fiber unbreakable plastic. The material for a given application is selected based on where it will be used. Galvanized tray may be made of pre-galvanized steel sheet fictitious into tray, or may be hot-dip galvanized after manufacture. When galvanized tray is cut to length in the field, usually the cut exterior will be painted with a zinc-rich multifaceted to protect the metal from deterioration. Regular housecleaning is important for protection, as cable trays are often installed in hard to reach places. Flammable dust and clutter may accumulate if the trays are not usually checked and kept clean
