Cable Tray: Types And Characteristics
Posted by william Rocher on December 9th, 2019
Cable trays are structures used for supporting insulated electrical cables as a part of the cable management system in commercial and industrial construction. The system is designed to withstand the severe environments and protect the wire’s hazardous conditions. The trays are recommended by the National Electrical Code (NEC) for power distribution and routing. Manufacturers of cable tray systems are obliged to test their products for ratings relative to flammability resistance, mechanical resistance, and temperature limitations. If you want to install cable trays in your workstation, call an electrical cable supplier that offers an extensive line of precisely engineered products.
Types of cable trays
The cable trays are designed to comply with standards of NEC Section 392.10 (A) and they are familiar with all these rules to meet all application requirements and NEC requirements. The most widely used cable trays are:
Channel Cable Trays
They are used for installation with limited trays where the cables exit through the cable channel. The standard length of 12 feet to 24 feet and the standard width is 3, 4, & 6 inches in metal systems and up to 8 inches in nonmetallic systems. This system is an economical way of enhancing reliability.
Ladder Cable Trays
They have solid side rail protection that allows the free flow of air through the system. The trays are generally made with a support span of 12 - 30 feet and standard widths of 150 to 900 millimetre. They are great for resisting excessive heating issues and preventing explosions when exposed to gasses in the conduit.
Single Rail Cable Trays
These trays have the potential to support ample cable to route in the system. They are flexible to the wires and a good choice for low voltage and low power cables. The standard width of these trays are 6 to 25 inches, depth are of 3 to 6 inches, and lengths are 10 to 12 feet during installation.
Solid Bottom Cable Trays
They are a great option for minimal heat generating electrical or telecommunication applications. These trays are non-ventilated and they can be used for applications that require EMI shielding. If you are looking for a cable tray support for critical projects that require absolute safety, galvanized solid bottom is the best choice. Standard width is 6 to 36 inches, depths of 3 to 6 inches, and length of 10 to 24 feet.
Wire Mesh Cable Trays
They are generally used for businesses that are involved in telecommunication and fiber optic applications. Stainless steel wire mesh and zinc plated trays can support systems for low voltage. They have a standard depth of 1 to 4 inches and length is about 10 feet.
