What is the bend size of a cable tray with a 25-degree incline
To calculate the size of the cut-out in the cable tray in this situation you divide the distance between sets by the width of the cable tray ie. Choose a cable tray fitting with a radius equal to or greater than your calculated minimum. Common standards are 300, 450, 600, and 900 mm. Use this tool to estimate sloped section length, horizontal run requirement, cut marks, and installation feasibility. The cable is pulled at the center of this cable tray. During installation, cables are bent or flexed in various environmental conditions (Sometimes bent way too far!).
