A comprehensive OHTL stringing project typically involves several critical stages:

1. Preparation: Site preparation, access road construction, tower erection, and installation of stringing accessories like conductor stringing blocks (sheaves) on towers.

2. Pilot Line Stringing: Pulling a lightweight pilot rope (often by drone or helicopter in challenging terrain, or by lighter pullers) through the stringing blocks.

3. Pulling Rope Installation: The pilot rope then pulls a stronger pulling rope (often an anti-twist steel wire rope) through the blocks.

4. Conductor Stringing: The main conductors are then attached to the pulling rope and pulled through the stringing blocks using powerful hydraulic pullers while hydraulic tensioners control the back tension.

5. Sagging & Clipping: Once pulled, the conductors are precisely sagged to meet design specifications, often involving specialized sagging equipment and methods. After sagging, conductors are "clipped-in" to their permanent insulator clamps, replacing the stringing blocks.

6. De-tensioning & Final Adjustments: Removing the tensioning equipment and performing any final adjustments or inspections. Our range of OHTL tension stringing equipment supports every one of these vital stages with precision and reliability.
