What is "tension stringing" in overhead power distribution lines, and why is it preferred over other methods?

2025-07-19

Tension stringing is a sophisticated method for installing overhead conductors where the conductor is pulled under a controlled tension, preventing it from touching the ground or any obstacles. This method is preferred because it:

  • Minimizes conductor damage: By keeping the conductor off the ground, it avoids abrasions, nicks, or kinks that can occur with traditional "slack stringing" methods.

  • Ensures safety: It significantly reduces the risk of accidental contact with energized lines, structures, or personnel, especially when stringing over existing infrastructure, roads, or populated areas.

  • Maintains precise sag and tension: OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioners and pullers allow for accurate control of conductor sag, which is critical for meeting design specifications and ensuring optimal electrical performance and mechanical stability of the line.

  • Reduces environmental impact: Less ground disturbance is required, protecting sensitive ecosystems.
