Cable bridges are an important device used to support and protect cables. They are usually widely used in places such as buildings, industrial facilities and public places. 　　According to different designs and uses, cable trays can be divided into the following classifications:

1、Suspended cable trays

Suspended cable trays support cables by means of brackets suspended from ceilings or walls. They are usually made of metal materials with high strength and durability. Suspended cable bridges are suitable for cable routing that requires long spans, such as large factories and commercial buildings.

3、Groove type cable tray

Trench type cable tray installs cables by building a trench on the ground or wall. Trench cable trays are usually made of concrete or steel and can provide good protection and support. They are commonly used for underground cabling and areas that need extra protection, such as factory floors and underground parking lots.

4、Trapezoidal cable trays

Step type cable trays have a series of parallel beams that resemble stairs. Cables can be routed along the beams and fixed by brackets. Step cable trays are suitable for applications where cables need to be transferred between different heights, such as large server rooms and data centers.
