What is the standard procedure for conductor stringing on an overhead transmission line?
2025-08-08Answer (from Ningbo Changshi): The standard procedure for OHTLstringingequipment.com/Conductor-Stringing-Equipment.html target='_blank'>conductor stringing involves a series of carefully planned steps to ensure a safe and successful installation. Our comprehensive approach, which utilizes our specialized equipment, includes:
-
Preparation: A thorough site assessment is conducted, including clearing the line route and setting up all the necessary stringing equipment, such as our hydraulic pullers and OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioners, at designated locations.
-
Pilot Wire Installation: A small pilot wire is pulled across the entire section of the line, threaded through the running blocks (sheaves) on each tower.
-
conductor pulling: The main conductor is then attached to the pilot wire and pulled through the running blocks. Our hydraulic pullers ensure a smooth, controlled pull, while our Tensioners maintain constant tension to keep the conductor off the ground, preventing damage.
-
Sagging and Tensioning: Once the conductor is in place, it is "sagged" to its precise final tension using instruments like a dynamometer. This step is critical for safety and long-term line performance, ensuring the wire has the correct slack (sag) for all weather conditions.
-
Clamping and Installation: The conductor is then secured to the towers with permanent clamps, and the running blocks are removed. Finally, spacers and other accessories are installed to complete the project.
