A successful tension stringing operation requires a coordinated system of specialized equipment working in unison.

1. Preparation:

   • Pilot Line Installation: A lightweight, non-conductive rope (pilot line) is first pulled across the spans, often by a drone or manually. This rope is then used to pull the heavier, anti-twisting steel pulling rope.

   • Equipment Setup: A hydraulic OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioner is positioned at one end of the section with the conductor reel, and a hydraulic puller is set up at the other end.

2. The Pull:

   • The hydraulic puller starts to pull the steel wire rope, which is connected to the conductor by a specialized conductor pulling grip and a Swivel to prevent twisting.

   • Simultaneously, the hydraulic OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioner applies a controlled back-tension to the conductor. This is the key to the entire process, as it keeps the conductor elevated and taut as it moves through the Stringing Blocks (sheaves) on the tower arms.

3. Sagging & Termination:

   • Once the conductor is fully installed in the section, the tension is adjusted to achieve the pre-calculated sag. This is a crucial step that ensures the conductor's safety clearances are met and the tension is within safe limits for the supporting structures. Our sagging scopes are used for this.

   • Finally, the conductor is secured to the dead-end towers with tension clamps, and the temporary Stringing Blocks are replaced with final suspension clamps.
