Partition plates in vertical cable trays are fixed using bolts or clamps through pre-drilled holes, ensuring proper alignment, secure fastening, and compliance with load and spacing standards.

Step-by-Step Guide

1. Inspect the Tray and Partition Plate Before installation, check the vertical cable tray and partition plate for any damage, corrosion, or deformation. Ensure the tray is properly supported and aligned vertically, with deviations not exceeding 3 mm per meter and total deviation ≤ 10 mm . 2. Align the Partition Plate Position the partition plate inside the tray at the required location. Ensure it is perpendicular to the tray sides and properly aligned with any existing partitions or cable layers. Maintain the recommended spacing between power and weak-current trays (≥150 mm) if applicable . 3. Select Appropriate Fasteners Use nuts and bolts compatible with the tray material. Typically, M12 or larger bolts are recommended for vertical trays, especially when supporting heavy cable loads . Ensure bolts are corrosion-resistant if the tray is galvanized or aluminum. 4. Secure the Partition Plate Insert bolts through the pre-drilled holes in the partition plate and the tray sides. Tighten nuts using a torque wrench to the manufacturer's recommended torque to prevent loosening due to vibration . For some systems, clamps or quick-connect systems may be used for faster assembly, but bolts provide the most reliable long-term stability. 5. Verify Stability and Clearance After fastening, check that the partition plate is firmly fixed and does not move. Ensure there is sufficient clearance for cables and that the plate does not interfere with cable routing or firestop requirements . 6. Repeat for Additional Plates If multiple partition plates are required, repeat the alignment and fastening process for each plate, maintaining consistent spacing and alignment throughout the vertical tray. 7. Final Inspection Perform a final inspection to ensure all plates are secure, bolts are tightened, and the tray system meets load-bearing and fire-resistance standards. Confirm that the installation complies with relevant codes such as GB 50303 or local electrical standards . By following these steps, partition plates in vertical shaft cable trays will be securely fixed, ensuring mechanical stability, proper cable separation, and long-term system reliability.
