What are the main steps in an overhead cable pulling (tension stringing) operation?

2025-08-15

A typical tension stringing operation follows these well-defined steps:

  1. Pilot Rope Stringing: A lightweight pilot rope is pulled between the OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioner and puller using a small winch or manual methods. This rope is used to then pull the heavier pulling rope.

  2. Pulling Rope Installation: The pulling rope (often a braided steel wire rope) is attached to the pilot rope and pulled through the running blocks.

  3. conductor pulling: The conductor is attached to the pulling rope using a Swivel and pulling grip. The hydraulic puller then pulls the conductor, while the hydraulic OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioner applies a constant back tension.

  4. Sagging and Clipping: Once the conductor is in place, a team "sags" the line to the correct tension according to engineering specifications. The conductor is then permanently secured to the insulators and the running blocks are removed.
