What are the key features to look for when choosing a hydraulic tensioner?
2025-08-13Choosing the right OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioner is crucial for project success. Here are some key features to consider:
-
Bullwheel Diameter and Number of Grooves: The diameter of the bullwheels and the number of grooves are essential. Larger diameters are gentler on conductors, especially sensitive ones like OPGW, and a greater number of grooves allows for higher load capacity and smoother operation.
-
Constant Tension Control: Modern, high-quality OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioners should have a hydraulic system that can maintain a constant tension regardless of the stringing speed. This is vital for achieving a uniform sag and tension across all spans.
-
Line Pull Gauge and Over-Pulling Protection: A precise dynamometer or line pull gauge allows the operator to monitor the tension in real time. Our machines also feature an automatic over-pulling protection system that prevents damage to the conductor or equipment by stalling the operation if the preset maximum tension is exceeded.
-
Negative Self-Acting Brake: This is a critical safety feature. A reliable brake system will automatically engage in the event of hydraulic failure, ensuring the conductor remains suspended and doesn't run away.
