    Disadvantages of cable tray compensation devices

    However, there are also disadvantages of using cable tray that need to be considered. While cable trays offer good structural support, they may not provide as much protection against physical damage or environmental hazards compared to fully enclosed conduit systems. Solid trays serve as electromagnetic shields and protect control and data cables from RFI interference. This issue can be addressed by adding perforations for continuous drainage, provided the trays are not used as a shield. One is a Cascade-type cable tray,It has the advantage of light weight, small footprint, relatively low cost, beautiful shape, good ventilation and heat dissipation. For the laying of large diameter cables, this equipment is undoubtedly.
