Achieving precise sag and tension in long-span or challenging terrain overhead stringing is critical for line performance and longevity. Best practices include:

• Detailed Stringing Charts: Pre-calculating sag and tension values based on conductor type, span length, temperature, and specific design criteria is fundamental. Our equipment supports the precise application of these calculated values.

• Advanced Puller-OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioner Synchronization: Utilizing puller-OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioner systems with synchronized controls ensures that consistent tension is maintained across the entire span, preventing slack or excessive tension that can lead to conductor damage or incorrect sag.

• Real-time Tension Monitoring: Operators continuously monitor tension readouts on the puller and tensioner, adjusting as needed to match the stringing chart specifications. Some advanced systems offer automated feedback to maintain target tension.

• Use of Sagging Sights/Targets: For final sag verification, optical sagging sights or drone-based measurement systems are used to accurately measure the actual sag in a span and compare it to design specifications, especially in complex terrains.

• Controlled Stop-and-Go Procedures: When stringing over undulating terrain or long spans, controlled stop-and-go procedures with proper braking on the tensioner are essential to prevent conductor run-back or surging.

• Environmental Compensation: Accounting for temperature variations and wind effects during stringing is crucial, as these factors directly influence conductor sag and tension. Operations may be adjusted or paused during extreme conditions.

Our tension stringing equipment is designed to facilitate these best practices, providing the precision and control needed for even the most demanding projects.
