In the Electrical wiring of Buildings / Malls / Cement Plant / Power Plant, a cable Tray system is used to support insulated electric cables used for power distribution & communication. Cable Trays are used as an alternative to open wiring or electrical conduit systems & are commonly used for cable management in commercial & industrial construction. They are especially useful in situations where changes to a wiring systems are anticipated, since new cables can be installed by laying them in the Tray, instead of pulling them through a pipe.
