Fabrication of 90-degree elbow cable trays
Creating a 90-degree elbow in an electrical cable tray, often called a "fabricated" or "mitered" bend, involves cutting, bending, and fastening a straight section of tray. The most common method involves creating two 45-degree cuts to form a 90-degree angle. The length of the bottom side (bottom diagonal) after bending the cable tray should be equal to the width of the cable. Ladder cable trays are critical components in modern electrical infrastructure, providing robust support and organization for cables. This manual is designed to guide workers through the detailed production process of ladder cable trays, including the manufacture of horizontal elbows, tees.
