What Are The Types of Cable Trays

There are many types of cable trays, which can be classified from multiple perspectives. Here are some common classification methods and specific types:

1、 Classified by Material

Metal bridge: The most commonly used type of bridge, with commonly used materials including steel, aluminum, etc. These cable trays have high strength and load-bearing capacity, suitable for various industrial and commercial environments.

Fiberglass bridge frame: made of unsaturated polyester resin and glass fiber composite molding, it has the advantages of corrosion resistance, aging resistance, and light weight, especially suitable for humid and highly corrosive environments.

Plastic bridge frame: made of polyvinyl chloride (PVC) or polyester profiles, with good insulation and anti-corrosion properties, but relatively low load-bearing capacity, suitable for occasions with low strength requirements.

2、 Classified by structural form

Trough type cable tray: with a groove shaped cross-section, it is the most common type of metal cable tray, which has dust-proof and anti-interference properties, and is suitable for laying computer cables, communication cables, etc.

Tray type cable tray: It has the advantages of light weight, large load capacity, beautiful appearance, simple structure, and easy installation. It is suitable for installing both power cables and control cables.

Ladder type cable tray (ladder type cable tray): The cross-section is trapezoidal, with a large bearing capacity, good heat dissipation and breathability, but relatively weak dust and anti-interference performance, suitable for laying cables with generally larger diameters.

Grid format cable tray: composed of metal rods and connectors, forming a mesh structure, suitable for power and communication cable wiring, and is an extension of traditional cable trays.

Composite cable tray: a new type of cable tray with the characteristics of simple structure, flexible configuration, convenient installation, and novel form, suitable for laying various projects, units, and cables.

3、 Classified by purpose

Power cable tray: used to support and protect power lines, usually installed on the ceiling or walls of buildings.

Communication bridge: used for installing and protecting communication lines, such as telephone lines, network lines, etc.

Pipeline bridge: used to support and protect various pipelines, such as water supply pipelines, drainage pipelines, etc.

4、 Classified by laying method

Direct burial type: The cable is directly buried underground.

Laying in trenches (tunnels): When concealed along the ground, wires and cables are placed in sealed conduits and then placed in the well chamber.

5、 Other classification methods

Classification by height: The height of the bridge frame can also be used as a basis for classification, such as 6 meters, 8 meters, 10 meters and other bridge frames of different heights.

Divided by material: such as aluminum alloy cable tray, stainless steel cable tray, hot-dip galvanized cable tray, etc. These cable trays have different properties and uses due to differences in material.

In summary, there are many types of cable trays, and the selection needs to be comprehensively considered based on the specific usage environment and requirements.
