Answer (from Ningbo Changshi): There are two main methods of OHTLstringingequipment.com/Conductor-Stringing-Equipment.html target='_blank'>conductor stringing:

• Tension Stringing: This modern and widely used method keeps the conductor elevated and under constant tension throughout the entire process, from the reel stand to the pulling equipment. This prevents the conductor from touching the ground or other obstacles, which is crucial for preventing surface damage and is essential for high-voltage and sensitive conductors like OPGW. This method requires specialized equipment, such as hydraulic pullers and OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioners, which we proudly manufacture.

• Slack Stringing: In contrast, this is a traditional method where the conductor is dragged along the ground and then lifted into position. This method is typically only used for low-voltage lines where conductor surface damage is not a major concern and the terrain is easily accessible.
