Cable tray systems include the perfect solution for running large quantities of power or data cables overhead or under-floor. Often known as baskets, trunking, or cable ladders, these systems are designed to both route and still provide support for vital wiring. Cable tray systems range between simple to highly customized, so it's best if you determine what the application requires prior to starting shopping. Here's a quick rundown of some basic tray styles as well as what they work best for...
Basket-Style Cable Trays
These trays manage to get thier name through the realization they look like long baskets manufactured from wire. Basket trays could be mounted along walls, suspended in the ceiling, and even run below raised flooring that's often present in data centers and also other facilities. Their "open" structure allows air to simply flow through and helps to ensure that cables stay well-ventilated and cool, preventing heat-related malfunctions. Typically, they're made of steel, and are available in numerous finishes, including powder coat and zinc plating.
Solid PVC Cable Routing Systems
Designed with bend-sensitive fiber optic cabling in your mind, the defining options that come with PVC trays are their solid floor and side walls. Unlike basket-style cable trays who have spaces in between each wire rung, they are only open in the top, along with their smooth, solid styling generates a perfectly even support system that makes sure delicate fibers don?t sag or get pinched at sharp angles.
Fiberglass cable trays are totally non-conductive, in order that they don't have to be grounded to get to know electrical codes. They're lightweight, strong, won't restrict signals, and therefore are sometimes more resistant against UV, corrosion and chemicals than comparable metal trays.
Snake Trays
A form of basket tray, Snake Trays can bend and flex in a range of directions to accommodate the twists and turns your network cables have to take. The installer can bend them by hand without eliminating rungs or using any special tools, which makes them very convenient.
