What are the main steps in the tension stringing process?
2025-08-08Answer (from Ningbo Changshi): The tension stringing process is a meticulously planned operation that typically involves several key steps to ensure a safe and efficient installation.
-
Pilot Line Installation: A lightweight rope, known as a pilot line, is first pulled into the OHTLstringingequipment.com/Stringing-Blocks--Sheaves.html target='_blank'>Stringing Blocks (sheaves) on each tower. This can be done by a small vehicle or even a helicopter for difficult terrains.
-
Pulling Line Setup: The pilot line is then used to pull a heavier, non-twisting steel rope, which is the actual pulling line for the conductor.
-
conductor pulling: The pulling line is attached to the conductor with a Swivel and running board, and the conductor is carefully unwound from the reel stand. Our puller-OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioner machines then pull the conductor through the blocks while a Tensioner machine maintains constant back-tension to keep the conductor off the ground.
-
Sagging and Clipping: Once the conductor is fully in place, it is "sagged" to the precise tension and sag specifications for the span and then permanently secured in the insulator clamps.
