Cable trays are used to house cables that need to cross traffic areas or be hidden. They can be made of different materials and are popular in industrial settings to avoid tripping hazards. Cable ducts allow for the passage of multiple cables and can be secured with brackets or adhesive. Once in place, the conduit is applied over the top of the cable to hide it from view.
A cable tray is a form of housing for a run of cables that must cross a traffic area such as a door or be slid up a wall without being seen. Depending on the environment and intended use, the cable duct can be made of different materials. The materials range from plastic of any color to stainless steel.
The use of cable ducts and trunking has become very popular, as many people do not want to go through the chore of running cable under existing carpeting or flooring. Also, running cable under floors isn’t an option in cases where the flooring method used is solid, such as tile or laminate flooring. Channels and raceways, on the other hand, run both along the floor and on the plinths of the room, allowing the cable to be hidden from view and protected from trampling.
The industrial uses of cable trays allow multiple lengths of cable to be run through high traffic areas without posing a tripping hazard. In industrial environments, a cable duct allows the passage of many cables required for different types of networks. They are often used for monitors that run in sequence relative to each other. Examples where cable ducts are used include CCTV monitoring systems or computer networks that are wired to servers or to each other to operate in a network-based fashion.
In these industrial environments, the cable trunking system allows cables to be hidden without having to route the cables inside walls and under different floors. It also allows the user to avoid running cables or the cabling system through ceiling structures or ceiling tiles. Due to safety code issues in some areas, running cables through floors or ceilings is not a legal option in an industrial setting, so cable ducting is the only cost-effective option for signal transfer to multiple go out.
Most cable tray systems are extruded, which means they are formed as they are forced through a forming machine. Unless the cable duct was made as a one-piece duct unit, as in many flooring applications, the typical cable duct system is a two-piece application. In these applications the bracket or cleat that holds the conduit or actual cable cover in place is screwed to the wall or secured by a high-strength adhesive that holds the cleat in place.
Once the cleat determines the route of the raceway, the cable is slid against the cleat. The conduit can then be applied over the top of the cable, hiding the often unsightly cords from view. The top of the duct is often applied to the cleat through the use of a snap tension formation, meaning that the top cleat simply “snaps” into place.
