How many degrees should the cable tray be bent
For low-voltage cables, the minimum bending radius is commonly six times the cable's outer diameter. If fabricating, mark the side rail at intervals based on the calculated arc length, cut V-notches, and bend the tray until the gap closes. The bending radii stated always apply at an ambient temperature of (20 ± 10)°C and are always measured at the inner curvature of the cable. The method for producing bridge bend elbows is as follows: Take a 90-degree cable tray bend elbow as an example, and apply the same principles for 45-degree bends accordingly.
