How to connect a half-bend tee in a cable tray

A half-bend tee in a cable tray is connected by cutting and bending the tray sidewalls, aligning the tee, and securing it with splice plates or brackets to ensure proper support and cable protection.Step-by-Step Connection Process

1. Prepare the Main Tray and Tee

• Identify the location where the half-bend tee will branch off from the main tray.
• Measure and mark the cut lines on the main tray to accommodate the tee's throat, ensuring the bend radius matches the cable requirements . 2. Cut and Bend the Tray
• Use a bolt cutter or appropriate cutting tool to make precise cuts in the main tray sidewalls where the tee will connect .
• Bend down the sidewalls of the main tray to create a smooth interface for the tee. This prevents sharp edges from damaging cables . 3. Align the Half-Bend Tee
• Position the half-bend tee so that it aligns with the main tray and maintains the correct bend radius for the cables.
• Ensure the tee's open side faces the direction of the branch run, and the tray edges are flush for a secure fit . 4. Secure the Tee
• Attach the tee using splice plates or TX brackets on both sides of the connection. Use bolts and nuts (e.g., SBH or CNH splice hardware) to fasten securely .
• Ensure the smooth head of the bolts faces inward to avoid cable damage .
• For wire mesh trays, rubber caps can be used to cover cut ends for additional protection . 5. Verify Installation
• Check that the tee is level and properly supported.
• Confirm that the bend radius meets the minimum requirements for the type of cables being installed .
• Ensure all fasteners are tight and the connection is stable before laying cables.

Additional Tips

• Half-bend tees can be fabricated on-site for faster installation, especially in wire mesh trays .
• Always use two splice plates per tray length to maintain structural integrity .
• If the main tray needs modification, minor trimming or chopping may be required to fit the tee properly . By following these steps, a half-bend tee can be securely and safely integrated into a cable tray system, maintaining proper cable support and minimizing the risk of damage.
