Present day, people are depending a lot on cable trays for both industrial as well as commercial constructions. They have become have become a necessary part as they are quick, highly economical and very flexible solutions to the complex construction problems. With cable trays at hand, people in the concerning field can easily support different types of wiring including High Voltage Power Lines, Power Distribution Cables, Sensitive Control Wiring, Telecommunication Wiring and Optical Cables.
Cable trays are made of different materials so they can suit the purpose of use easily. The most common metal used to make cable trays is a corrosion-resistant metal which can be low-carbon steel, an aluminum alloy or stainless steel. If people want something in corrosion-resistant finish then they can go for zinc or epoxy. The choice of material usually depends on the type of installation and the environment where the installation is done. Cost is also a factor to choose the material.
There are many different varieties of cable tray types to choose the requirement. The six basic types of cable trays are:
Ladder Type Cable Tray:
They are generally used in applications that need intermediate to high support ranging between 12 to 30 feet. These are used in almost 75 percent of cable tray system installations in Dubai. Ladder cable trays are much preferred because they allow maximum free flow of air to the cables. They also allow the cable heat to dissipate effectively.
Solid Bottom Cable Tray
These are usually used for heat generating telecommunication or electrical applications. The support they offer spans 5 to 12 feet and the main reason that they are preferred by professionals is their shielding. Solid bottom steel cable trays provide EMI/ RFI shielding for highly sensitive circuits.
Trough Cable Tray
The trough cable tray is usually used for application that release moderate heat and their support range spans from short to intermediate —5 to 12 feet. They offer moderate ventilation with extra cable support frequency and this type of tray is available in both metal as well as nonmetallic materials.
Channel Cable Tray
These are used in installations that have limited numbers of tray cable in cases where the behavior is undesirable. Channel cable trays offer support frequency of short to medium that spans 5 to 10 feet. They provide economical support for cable drops.
Wire Mesh Cable Tray
The wire mesh cable tray type is generally used for applications of telecommunication and fiber optics. They are used for installations requiring short support spans ranging from 4 to 8 feet. They also provide field adaptable support system for low voltage applications.
Single Rail Cable Tray
The single rail cable tray type is another variety that is generally used for cable installations that need low voltage and power. These installations require maximum cable freedom, installation speeds and side fill and hence single rail cable tray is apt.
