Professional Answer: The strategic use of a bridge type cable laying roller is paramount in maintaining the minimum recommended bending radius of a cable during installation. By raising the cable over obstacles, the rollers prevent the cable from making sharp, damaging bends that could compromise its integrity. The smooth, wide-waisted rollers minimize friction and distribute the pulling tension evenly along the cable, thereby protecting the outer sheath and internal conductors from stress. Adhering to the correct bending radius and tension limits is a fundamental best practice in the industry, and our specialized rollers are engineered to make this process both effortless and secure, extending the lifespan and performance of the installed cables.
