Our Professional Answer: Reducing friction is one of the most critical factors in underground cable installation. Excessive friction can cause the pulling tension to exceed the cable's maximum allowable limit, leading to damage to the cable's sheath and internal conductors. This can compromise the cable's lifespan and lead to costly repairs or failures.

To mitigate this risk, our clients rely on specialized tools and materials:

• underground-Cable-Laying-Equipment-and-Tools.html target='_blank'>cable rollers: These are placed inside the trench or conduit to support the cable and allow it to be pulled smoothly. We offer a variety of rollers, including corner rollers and straight rollers, designed to accommodate different cable sizes and routes.

• Cable Lubricants: High-performance, water-based lubricants are applied to the cable as it is pulled. These lubricants significantly reduce the coefficient of friction, allowing for longer pulls and reducing the strain on both the cable and the pulling equipment.

• Cable Pulling Winches: Our hydraulic and diesel-powered pulling winches are equipped with tension measurement systems to ensure the pulling force remains within safe limits. This precise control is vital for preventing cable damage and ensuring a safe, efficient installation.

Using the right combination of rollers, lubricants, and controlled pulling equipment ensures the integrity of the cable and a successful installation.
