Professional Answer: While both applications require immense force and precision, the equipment is tailored to the specific environment.

• Overhead Stringing Equipment: The focus here is on puller-OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioner systems. These machines work in tandem on opposite ends of the line section to string conductors with controlled tension, ensuring correct sag and preventing ground contact.

• underground Laying Equipment: For underground projects, the primary machine is a hydraulic winch or puller used in conjunction with Cable Feeders. Winches provide the immense force needed to pull cables through ducts, while feeders assist in pushing the cable from the reel stand, easing the load on the pulling equipment and the cable itself.
