How is cable pulling tension managed to prevent damage during installation?

2025-08-14

Managing pulling tension is crucial to avoid damaging the cable's inner conductors or insulation. We recommend the following:

  • Pulling Force Calculation: The maximum pulling tension is calculated based on the cable's size, material, and route. This value must not be exceeded.

  • Hydraulic Pullers: Using hydraulic cable pullers equipped with tension recorders ensures a controlled, constant pull and provides a real-time record of the force applied.

  • Specialized Equipment: underground-Cable-Laying-Equipment-and-Tools.html target='_blank'>cable rollers are used at regular intervals to reduce friction, and guide sheaves are installed at bends to maintain the minimum bending radius and prevent excessive sidewall pressure.

  • Swivels and Grip: A pulling Swivel should be used between the pulling rope and the cable grip to prevent twisting.
