How to cover cable tray bends with caps

To cover a cable tray bend, use a compatible tray cover or cap designed for bends, ensuring it fits securely and protects the cables from damage. Steps to Cover a Cable Tray Bend1. Choose the Right Cover Type Select a cover that matches your cable tray system.

Options include dome, flat, peak, finned, corrugated, ventilated, or perforated designs depending on whether the installation is indoor or outdoor and the level of protection required. Ensure the cover complies with relevant standards such as NEMA, CE, IEC, UL, or IP ratings. 2.

Measure and Prepare the Bend Measure the bend angle and tray width accurately. For wire mesh trays, bends can be made on-site using a bolt cutter or bending tools, which also allow protective caps to be fitted over cut ends. 3.

Fit the Cap or Cover

For pre-fabricated covers, select a bend-specific piece if available. Many manufacturers provide 90-degree or custom bend covers. For custom solutions, you may need to cut and bend a sheet metal cover to match the tray bend, ensuring it fully encloses the cables.

Secure the cover using bolts, clamps, or snap-on mechanisms depending on the tray system. Ensure the cover does not pinch or stress the cables. 4.

Verify Protection and Clearance Check that the cover fully protects the cables, especially at the edges and corners. For wire mesh trays, rubber caps can be used to protect cut ends and prevent abrasion. Ensure there is enough clearance for cable expansion and maintenance.

5. Optional: Fabrication or Modeling For complex installations, you can model the cover as a separate family in CAD software or use fabrication parts to create a custom lid. This is particularly useful for non-standard bends or when precise alignment is required.

By following these steps, you can safely cover cable tray bends, maintain cable integrity, and comply with installation standards.
