Today, our Cable Tray manufacturer brings us information on the selection and planning of cable trays. Let's learn together about the factors to consider in cable tray selection and planning!

1. There are generally three types of environmental conditions for confession: corrosive environment, normal environment, and special environment.

2. According to the direction of most cables, they can be routed along columns, beams, and floors indoors, and along process pipelines as much as possible outdoors.

3. Calculate the weight q and total load G of the unit length cable on the cross-section of the cable tray for load calculation

4. The selection of cable trays is based on the cable load and the environment of the tray equipment, using the load curve of the tray as the basis to determine the type and standard of the tray, as well as the spacing between columns, the length of the support arm, the level of the tray, and the length of the columns.    

5. Determine the fixing method of the cable tray based on the cable routing and equipment environment; Hanging type, upright type (both of which can be fixed on one side or both sides), wall side type, etc.    

6. The hierarchical arrangement and interlayer spacing of various cables on cable trays.    

The placement of cable trays is as follows: weak current control cables are placed on the top layer, followed by general control cables, low-voltage power cables, and high-voltage power cables in sequence. This placement is beneficial for shielding, disturbing ventilation, heat dissipation, etc.
