1. Support and protection: withstand the weight of cables inside the cable tray and possible external impacts, protect cables from external collisions, compression, and wear, and maintain the overall shape and stability of thecable tray.
2. Prevent cable detachment: Ensure that the cable is always in a safe space inside the cable tray, ensuring that the cable laying is neat and orderly
3. Enhance sealing: Cooperate with the cover plate and bottom plate to form a relatively enclosed space, improve the sealing of the cable tray, reduce the possibility of dust, water vapor, etc. entering the interior of the cable tray, and provide a good operating environment for the cable
4. Auxiliary grounding: It can be used as a part of grounding to connect the cable tray to the grounding system, achieve safe grounding of electrical equipment, and ensure the safety of personnel and equipment
5. Easy to install: It is convenient to connect and fix with other components of the cable tray and external support structures, making it easy to install and debug the entire cable tray system
