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 Process1.

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 TipsHalf-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.
