How does a "hydraulic OPGW tensioner-puller" ensure constant tension and protect the optical fibers during stringing?
2025-07-21Our "hydraulic OPGW OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioner-pullers" are central to fiber protection through their advanced hydraulic and electronic systems:
-
Closed Hydraulic Circuit: This system provides exceptionally smooth, stepless speed and tension control in both pulling and tensioning modes. It eliminates jerks and sudden changes in force that could stress or damage the optical fibers.
-
Automatic Tension Control (ATC): The machine's electronic control unit continuously monitors the OPGW tension via a precise dynamometer. If the tension deviates from the pre-set value, the hydraulic system automatically adjusts to maintain the constant desired tension, ensuring the OPGW is always within its safe working limits.
-
Overload Protection: Integrated safety features, often with audible alarms and automatic machine shutdown, prevent the application of excessive tension, safeguarding both the OPGW and the equipment.
This combination of hydraulic precision and electronic control is paramount for achieving accurate sag and preventing any form of damage to the delicate optical core.
