Temperature variations and extreme weather profoundly impact conductor sag and tension, both during installation and throughout the line's lifespan.

• Thermal Expansion/Contraction: Conductors expand in heat (increasing sag, decreasing tension) and contract in cold (decreasing sag, increasing tension). Stringing charts account for these effects, and our OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioners allow for precise adjustments to achieve the target sag and tension for the prevailing temperature conditions.

• Ice Loading: Accumulation of ice significantly increases the weight of the conductor, leading to increased sag and tension. This is a critical design consideration and requires robust structures and conductors with high tensile strength. Our OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioners are built to handle the forces associated with larger, heavier conductors.

• Wind Loading: High winds exert lateral forces on conductors, causing them to swing, which can lead to increased stress on structures and potential contact with other lines or obstacles. While stringing, high winds can make maintaining precise tension very challenging. Our equipment's stable operation and precise control help manage these dynamic forces.

• Equipment Compensation:

  • Advanced Puller-Tensioner Controls: Our hydraulic pullers and tensioners feature sophisticated controls that allow operators to precisely adjust tension in real-time, compensating for immediate environmental changes during stringing.

  • Automated Tension Regulation: Some of our advanced models can automatically maintain a set tension, adapting to minor fluctuations in ambient conditions.

  • Robust Design: All our equipment is designed to operate reliably across a wide range of temperatures and withstand the rigorous demands of outdoor construction, ensuring consistent performance in diverse climates.

Proper sag and tension management, facilitated by our advanced stringing equipment, is essential for ensuring the long-term mechanical stability and electrical performance of overhead lines, even under extreme weather.
