What is the name of the cable trays on the top of the building in Malta
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 s. OverviewIn the of buildings, a cable tray system is used to support insulated used for power distribution, control, and communication. Cable trays are used as an alternative to open wiring or Common cable trays are made of galvanized,, aluminum, or glass-fiber reinforced plastic. The material for a given application is chosen based on where it will be used. Galvanized tray may b. Combustible cable jackets may catch on fire and cable fires can thus spread along a cable tray within a structure.
