Cable Support Systems

Cable support systems are material used for supporting collected cables and keeping them in an open area instead of letting them exposed and running throughout the walls. The construction in commercial, residential and industrial fields are major users of cable support systems as they serve one of the major foundations of an electrical system. Cable support systems are great alternative to open wiring and when new wirings are anticipated to be installed. This is advantageous at times when there are changes needed to be done on the cables in the future as they can be simply removed on the tray where they are laying. There are several types of cable support system available today that are built to match different applications of various industries.


Cable Tray

Cable trays are installed to walls and ceiling to carry cables. The installers used can be trapeze bar hangers or j-hooks. Cable trays can be made from fiberglass, steel or aluminium depending on the requirement of the application. The main factor that usually dictates what material to use is the local building code requirement. Another factor is the construction budget. The manufacturer and local inspectors will determine the number of cables that each tray can carry.


Cable Ladder

Cable ladder is a widely used type of cable support system. It is made up of two longitudinal side rails connected by rungs that helps secure the wirings in place. It can be installed with or without covers. Installing it without a cover allows air to freely flow around the cables to let heat escape. This is ideal to use when trying to achieve maximum ventilation. It also allows for cables and wires to be accessible from either side of the tray. Cable ladder comes in 10, 12, 20 and 24 feet in length.


Cable Trough

Similar to cable ladder, cable troughs comprise of two longitudinal side rails but with a solid bottom. They troughs are suitable for supporting wires or cables that produce a minimal amount of heat. They can provide best protection to cables and wires within especially on sensitive circuits. They can handle five to 12 feet long wires and can be bought with or without ventilation openings. Metallic and non-metallic cable troughs are available today.


Cable Trunking

A cable trunking system refers to a system of enclosures comprised of a base and a removable cover intended for the complete surrounding of insulated conductors, cables and cords. For the area of electrical installations, In order to conceal cables there are normally two options to go by. The first option is to recess the cables by channeling the walls, fitting new false panels, using ceiling voids or ripping up floors. The traditional alternative of fitting white box trunking with sharp edges can end up looking unfashionable in modern décor. D-line trunkings find particular appeal in retail premises, fire and security installation, office and residential properties and re-wiring projects. For basic socket circuits and lighting, there are snap-on accessories for certain trunking ranges so that while combining with D-line hinge and click-lock designs, electricians can easily fit through this trunking system.
