Tension Stringing with Tesmec Cable Hauling Equipment

The first goal when installing - or replacing in case of re-conductoring - an overhead single or bundled conductor(s) is to prevent its damage during stringing operations.

Tension stringing and power lines installation technology allows you to install the conductor under controlled mechanical tension, preventing it from touching the ground (or any infrastructure on the line path), and minimizing the impact on the line path.

Re-conductoring stringing operations, with energized line (possible only for lines with more than 2 circuits - one will be interrupted), are becoming more frequent and vitally important all around the world. Live line operations are the most efficient way to:
- replace old conductors when close to the end of their life,
- increase the capacity of an existing line, by replacing the ordinary conductors with the new generation ones like HTLS (High Temperature Low Sag).

The possibility of tension stringing all the conductors of a phase simultaneously is a great achievement for installation efficiency. Multiple stringing can perform up to eight conductor simultaneously, using multiple conductor machines or modular electronically synchronized machines.
The high precision and reliability of the tension control system, independent for every conductor, deliver the highest installation quality.
