Installation of horizontal elbows in wire mesh cable trays

Horizontal elbows in wire mesh cable trays are created by cutting, bending, and securing the mesh using specialized tools and connectors to form 90-degree bends.

Key Steps for Installation

1. Tray Preparation Turn the wire mesh tray open-side down to provide optimal access for cutting and bending. Identify the section where the horizontal elbow will be formed and mark the cutting lines according to the desired bend radius and tray width . 2. Cutting the Mesh Use an angular bolt cutter or a specialized mesh cutting tool (e.g., MM-ACC-BTC) to remove selected longitudinal and cross wires. Ensure cuts are clean and precise to maintain structural integrity. Typically, the cut length is slightly smaller than the tray width to allow proper bending . 3. Forming the Elbow Bend the tray along the cut lines to create a 90-degree horizontal elbow. Maintain the lowermost longitudinal wire to cap off the end and provide stability. Use a bending jig or manual bending techniques to achieve a smooth, uniform curve . 4. Securing the Elbow Attach inner radius brackets at the corners using appropriate clips (e.g., TM-CPL-JN2 or TM-CPL-JN3) to reinforce the elbow and prevent deformation. Ensure at least one clip per seam, with additional clips for taller trays or heavier cable loads . 5. Finishing Touches Install wire end protector caps (e.g., CC-KNB02) over exposed wire ends to prevent cable damage and ensure safety. Verify that the elbow maintains the correct angle and alignment with the main tray run .

Additional Considerations

• Material Selection: Choose galvanized steel, stainless steel, or powder-coated trays based on environmental conditions to prevent corrosion .
• Bend Radius: Follow manufacturer recommendations for minimum bend radius to avoid cable stress and maintain performance .
• Load Capacity: Ensure the elbow and tray system can support the intended cable weight, especially in horizontal runs.
• Compliance: Adhere to local electrical codes and industry standards for cable tray installation and safety. By following these steps, horizontal elbows in wire mesh cable trays can be installed efficiently, maintaining both structural integrity and cable protection. Proper cutting, bending, and securing are essential for a durable and safe cable management system.
