The cable tray can replace the electric pole, eliminating the electric pole project, and the effect is better. It can ensure the safety of the cable during use. Let's take a look at the practices and contents when selecting the style and variety of cable tray.
1. When the cable network requiring electrical or external interference (such as corrosive liquid, combustible dust and other environmental impacts) needs to be shielded, the channel type composite anti-corrosion shielded cable tray shall be selected.
2. In strong corrosive environment, flame retardant and anti-oxidation composite epoxy resin cable tray shall be selected. The same materials shall be selected for the upright and support to improve the service life of the bridge and accessories. Cover with panels in environments where dust tends to accumulate and where other covers and outdoor locations are required.
3. Shandong cable bridge manufacturer mentioned that in addition to the above, according to the site environment and technical requirements, bridge type, trough type, ladder type, glass cable bridge anti-corrosion and flame retardant or ordinary steel bridge can be selected. In the environment where dust is easy to accumulate, the panel shall be covered in the environment where other covers are required and in outdoor places.
4. In the public passage or outdoor crossing section, install cushion blocks at the bottom of the step or use pallets at this section. When a large span crosses the public passage, the bearing capacity of the rack can be increased, and the rack can be selected according to user requirements.
5. Composite bridge is selected for large span.
6. Composite epoxy frame is selected for outdoor use.
In addition, the selection of cable tray specification is also very important. The width and height of cable tray shall be selected according to the following table to ensure that the actual load rate of cable does not exceed the specified value of relevant standards. The power cable shall account for 40-50%, the control cable shall account for 50-70%, and the remaining equation development allowance shall be 10-25%. The specifications of various fixtures and accessories shall meet the engineering design conditions and match the bridge.
The above is the introduction of Shandong cable tray style and how to choose. When selecting, you should select the style and type, and then consider the specification to ensure that it can achieve good use effect. Follow our website for more relevant content http://www.sddlqj.cn Come on!
