How is tension control managed during the installation of MV cables?

2025-08-15

Tension control is the single most critical factor in MV cable installation. Exceeding the maximum allowable pulling tension can cause permanent damage to the conductor, insulation, or jacket, leading to premature cable failure. We address this with our equipment through:

  • Integrated Tension Meters: Our hydraulic pullers are equipped with a real-time tension meter, allowing the operator to constantly monitor the force being applied to the cable.

  • Tension Recording: For large projects, our machines can provide a digital output of the tension graph, which serves as a crucial part of the project documentation and quality control.

  • Push-Pull Capability: For extremely long or complex pulls, a puller-OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioner can be used at both ends of the run, with one machine pulling and the other feeding the cable under controlled tension.

All of our machines and accessories are designed to work together to keep the cable tension within the manufacturer's specified limits.
