Properly managing sag and tension is a fundamental step in the construction of any overhead power line. The process, known as sagging, involves adjusting the conductor to the correct sag-tension ratio for a given temperature, span, and loading condition.

At Ningbo Changshi, we provide a full range of high-quality tension stringing equipment designed to make this process safe and efficient. Our equipment ensures that conductors are kept off the ground throughout the entire stringing operation and are pulled to the precise tension required by engineering specifications. This approach minimizes damage to the conductor and ensures uniform tension across all spans, which is vital for long-term reliability and safety. We offer the necessary tools, including hydraulic OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioners, OHTLstringingequipment.com/Hydraulic-Conductor-Pullers.html target='_blank'>Conductor Pullers, and other specialized overhead line tools that are used by professionals worldwide to meet these rigorous demands.
