How are the cables fixed inside the vertical cable tray?

The cables inside the vertical cable tray can be fixed using various methods, and the following are some common practices:

1. Binding tape fixing method: Thread the binding tape through the cable and fix it on the inner wall of the bridge. This method is simple and easy to implement, but not suitable for large cables.  

2. Hook fixing method: Install hooks on the inner wall of the bridge and hang the cables on the hooks. This method is suitable for large cables, but requires additional processing of hooks.  

3. Ladder fixing method: Arrange the cables along a trapezoidal track, and then fix them on the track with binding tape. This method is suitable for large cables, but requires additional processing of trapezoidal tracks.  

4. Spiral fixing method: Arrange the cables along a spiral track, and then fix them on the track with binding tape. This method is suitable for large cables, but requires additional processing of spiral tracks.  

Regardless of the method used, the following points should be noted when fixing cables:

1. The fixation should be firm and not loose to avoid cable detachment or potential safety hazards.  

2. When fixing, the cable should be kept beautiful and tidy, and there should be no disorderly situation.  

When fixing, the selection should be based on the size and weight of the cable, and different cables require different fixing methods.
