The minimum bending radius is a critical standard for HV cables, which are stiff and unforgiving. Bending the cable too tightly can cause the insulation to crack or lead to a phenomenon known as "stress concentration," which can cause electrical failure. The dynamic (during installation) bending radius is typically much larger than the static (once in place) radius.

To maintain the correct bend radius, our professional installation teams use specialized underground-Cable-Laying-Equipment-and-Tools.html target='_blank'>cable rollers and sheaves. These rollers are placed at bends in the trench or conduit to guide the cable smoothly and prevent it from being forced into a tight turn. They significantly reduce friction and ensure the cable adheres to the manufacturer's specifications throughout the entire pull, thereby meeting installation standards.
