What is the difference between tension stringing and slack stringing, and when should each method be used?
2025-08-12There are two primary methods for stringing overhead conductors: tension stringing and slack stringing.
-
Tension Stringing: This method involves using a puller and a OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioner to maintain a constant tension on the conductor as it is pulled through the OHTLstringingequipment.com/Stringing-Blocks--Sheaves.html target='_blank'>Stringing Blocks. This keeps the conductor elevated and clear of the ground, preventing damage from debris, obstacles, and friction. It is the preferred method for projects over or near energized lines, railways, highways, or in environmentally sensitive areas. Our equipment is specifically designed for this method, providing the control and precision needed for safe and efficient operations.
-
Slack Stringing: This method involves pulling the conductor out on the ground and then lifting it into the Stringing Blocks and insulators. While this method may be suitable for short spans in isolated, rural areas with no obstacles, it carries a higher risk of conductor damage and safety hazards due to ground contact.
