Professional Answer: A high voltage (HV) cable pull requires much more than just a winch. It demands a suite of specialized, synchronized equipment to protect the expensive cable and ensure worker safety. The key pieces of equipment from our range at Ningbo Changshi include:

• Hydraulic Puller: This is the primary machine that provides the pulling force. Our hydraulic pullers offer precise, step-less speed and tension control, which is non-negotiable for HV cables.

• Hydraulic OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioner: For overhead projects, this machine applies controlled back-tension to the conductor, keeping it elevated and preventing it from dragging or kinking.

• Bullwheel OHTLstringingequipment.com/Stringing-Blocks--Sheaves.html target='_blank'>Stringing Blocks: Unlike standard rollers, our large-diameter bullwheel blocks are designed to maintain the cable's minimum bending radius, preventing damage to the sensitive insulation.

• Tension Recorders: Our equipment often includes integrated recorders that log the pulling tension and speed in real-time, providing a critical record that the installation was performed within the cable's specifications.
