What Happen to the Electric Wire When Bent？
If conventional cable bend radius is less than the minimum radius, the cable insulation can’t reach standard thickness because of convex curvature of cable end excessive bending, thus affecting the insulation effect, lead to cable breakdown, or even cause a fire or other accidents.
If the electric wire is armored cable, the problem is more serious, because bending over with armor will pierce the outer sheath and inner insulation, leading to accidents.
When you install the bridge, the bridge should be done to meet the bending radius. Do not install 90 degree; you can use two 45-degree angle cut to meet the 90 elbow.
