Cable tray 45-degree fittings

Specialty cable knowledge brief Published 26 Aug 2024

Prepared for preliminary research by the ZITHA SPECIALTY knowledge desk. Confirm fire performance, mechanical protection, loss budgets and installation requirements against current standards and product documentation.

Cable trays can be installed at a 45-degree angle using proper bending techniques, support spacing, and adherence to safety and design standards.Planning and Preparation

Before installation, review the Bill of Quantities (BOQ) to ensure all tray sections, fittings, and supports meet the project's size and weight requirements. Calculate the total cable weight per meter to select the correct tray thickness and support brackets. Supports are typically spaced 1.5 to 3 meters apart, with shorter spacing providing greater rigidity and longer spacing reducing material costs but requiring stronger trays . Inspect the site for accessibility, safety, and alignment with approved drawings .

Creating a 45-Degree Bend

To form a flat 45-degree bend in a cable tray:

  1. Identify the centerline of the tray where the bend will occur.
  2. Measure and mark the points on either side of the centerline to determine the section of the lip to be removed.
  3. File or cut the lip along the marked lines.
  4. Cut down the centerline and fold the tray so the cuts overlap, forming the 45-degree angle.
  5. For precision, take the desired angle (45°) and divide it by two (22.5°) to mark the bend accurately on each side .
Installation Steps
  1. Obtain approval for drawings and materials before starting.
  2. Install safety barriers and warning signs around the work area.
  3. Coordinate with other trades to prevent interference.
  4. Inspect all trays, conduits, and accessories for damage before installation.
  5. Mount the trays according to the approved layout, ensuring proper alignment and support spacing.
  6. Secure the trays with brackets, hangers, or threaded rods, maintaining the maximum load capacity per hanger (typically 318–340 kg) and support spacing (up to 3.6 m for ladder trays), .
  7. Label each tray section by feeder name and branch number for easy identification and future maintenance .
Safety and Compliance
  • Follow NEMA, IEC, or local electrical codes for tray installation.
  • Ensure trays are not overloaded to prevent sagging or bending.
  • Avoid sharp edges that could damage cables.
  • Use proper lifting techniques when handling long or heavy tray sections to prevent injury .
Summary

Installing cable trays at a 45-degree angle requires careful planning, precise cutting and bending, proper support spacing, and adherence to safety standards. By following these steps, the tray system will remain robust, safe, and accessible for future cable additions or modifications .
