Different types of cable tray are as follows:
Ladder Cable Tray
The ladder type cable trays are manufactured in the width from150 mm to 900 mm: having Height from 50 mm to 150 mm and the Thickness from16 SWG to 10 SWG with all accessories. These trays consist oftwo longitudinal side rails connected by individual transverse members.
Adder cable trayhas two longitudinal side members connected by individual transverse members, designed for use as powercableor control cable support.
Made from sheet metal
Made from angle and flats / Ducts
Ladder cable tray provides:
Solid side rail protection and system strength with smooth radius fittings and a wide selection of materials and finishes maximum strength for long span applications.
Standard widths of 6, 12, 18, 24, 30, and 36 inches
Standard depths of 3, 4, 5, and 6 inches
Standard lengths of 10, 12, 20 and 24 feet
Rung spacing of 6, 9, 12, and 18 inches
Ladder cable type is generally used in applications with intermediate to long support spans, 12 feet to 30 feet.
Solid bottom cable tray
The solid bottom tray is used to carry smaller instrumentation, data communications, computer, and telephone control and fiber opticcable from one location to another.
Channel cable tray
Channel cable tray system consisting of one piece, ventilated or solid bottom section, designed for use with a single power cable or multiple control or single circuit cables.
Single rail cable tray
Single Rail, Center-Supported cable traysystems save time and money in those lighter-dutycable support projects that do not require a traditional dual siderail cable tray. Single Rail Cable Tray is generally used for low voltage and power cables installations where maximumfreedom, side fill, and speed to install are factors.
Single rail tray provides:
These aluminum systems are the fastest systems to install and provide the maximum freedom fort cable to enter and exit the system.
Single hung or wall mounted systems insingle or multiple tiers.
Standard widths are 6, 9, 12, 18, and 24 inches.
Standard depths are 3, 4, and 6 inches.
Standard lengths are 10 and 12 feet.
Wire mesh cable trays
Wire mesh cable trays are used extensively for data cables and low voltage installations; steel wire trayhas become increasingly popular with installers thanks to its ease of use, flexibility and lightweight structure. They are appropriate for Sensitive cables such as control cables, optical cables, telecommunication cables, etc.
Features and Benefits of wire mesh cable trays:
1. Low cost.
2. Light in weight.
3. Easy for line check and cleaning.
4. Easy maintained.
5. Fast heat dispersion.
6. Cables can be secured to clamps or ties.
7. Flexible and fast installation.
8. Safe-T-Edge design to protect cables.
9. Strong enough to withstand short circuits.
