Modern hydraulic OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioners include spring-applied brakes that auto-engage on power loss or hose failure, keeping conductors and equipment at the same potential to prevent shocks. They also feature overpull protection (limits set by conductor type) and remote diagnostics (via IoT) to reduce on-site risk. On long spans, better tension control cuts twisting by ~50%, protecting insulators. These features (used by utilities worldwide) greatly enhance crew safety compared to unregulated pulling.
