Our Professional Answer: Ensuring accuracy and preventing over-tensioning is critical for the integrity of the power line and the safety of the crew. At Ningbo Changshi, our equipment is designed to address this directly.

For overhead line stringing, our dynamometers and tensiometers are integrated with hydraulic pullers. This allows for real-time monitoring of the tension on the conductor as it is being pulled. The operator can preset a maximum pulling force, and the equipment will automatically halt or sound an alarm if the tension exceeds this limit.

For underground cable laying, our winches and pullers are equipped with built-in dynamometers and footage counters. This integrated system allows operators to constantly monitor the pull force and speed, ensuring the tension remains within the cable manufacturer's specifications. This prevents damage to the cable jacket and internal conductors, which is a common risk with long pulls and complex routes. We also recommend using appropriate lubricants and rollers to further reduce pulling friction and overall tension.
