Ningbo Changshi’s latest stringing machine is a 1000kV-capable puller-OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioner engineered for ultra-high-voltage DC transmission. This new unit features extra-large bullwheel drums and a reinforced hydraulic drive to handle the heavier aluminum and composite conductors used in long-distance HVDC lines. It comes with fully remote operation: crews can control tension settings and monitor status from a safe distance. The machine’s electric-hydraulic control system ensures precise, constant tension during lengthy pulls, reducing the risk of conductor damage.

Key highlights of the 1000kV puller-OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioner include:

• Ultra-High Capacity Drums: Extra-large diameter pulleys built for continuous duty on very long spans, enabling efficient pulls over 50 kilometers without re-spooling.

• Advanced Digital Controls: A touchscreen interface provides real-time readouts of pull/push force and wire speed. Automated tension algorithms keep the conductor stress within safe limits during any overload or slack event.

• Remote Safety Features: Wireless control and integrated fail-safes allow operators to start/stop the machine and brake from distance, minimizing personnel on the line.

With this high-capacity model, Changshi customers can string 1000kV lines faster and safer. It is particularly suited for new HVDC projects connecting wind farms, solar farms or inter-regional links, where reliable long-span performance is critical. By combining raw pulling power with modern electronics, the puller-tensioner boosts productivity while meeting strict quality standards on ultra-high-voltage installations.
