Cable tray systems include the perfect solution for running bulk of power or data cables overhead or under-floor. Often known as baskets, trunking, or cable ladders, scalping systems are made to both route and supply support for vital wiring. Cable tray systems range between an easy task to highly customized, so it's smart to know what the job requires before you begin shopping. Here's a quick rundown of a few basic tray styles as well as what they work best for...
Basket-Style Cable Trays
These trays get their name from the fact they seem like long baskets made of wire. Basket trays can be mounted along walls, suspended from the ceiling, and also run below raised flooring that's often within data centers as well as other facilities. Their "open" structure allows air to easily flow through and means that cables stay well-ventilated and cool, preventing heat-related malfunctions. Typically, they're created from steel, and come in various finishes, including powder coat and zinc plating.
Solid PVC Cable Routing Systems
Designed with bend-sensitive fiber optic cabling in your mind, the defining popular features of PVC trays are their solid floor and side walls. Unlike basket-style cable trays that have spaces between each wire rung, they are only open on the top, and their smooth, solid styling generates a perfectly even support system that creates sure delicate fibers don?t sag or get pinched at sharp angles.
Fiberglass cable trays are totally non-conductive, so they won't need to be grounded to meet electrical codes. They're lightweight, strong, won't hinder signals, and so are often times more proof against UV, corrosion and chemicals than comparable metal trays.
Snake Trays
A form of basket tray, Snake Trays can easily bend and flex in a range of directions to allow for the twists and turns your network cables have to take. The installer can bend them personally without reducing rungs or using any special tools, making them very convenient.
