company news about Stable Tension Control with Hydraulic Puller and Tensioner for 220kV/500kV Lines in Vietnam

Vietnam’s high-voltage transmission projects have clear requirements for stringing tension accuracy and operational safety, especially in long-distance and complex terrain sections where stable and controllable traction equipment is essential. Hydraulic puller and tensioner are equipped with hydraulic dynamometer and oil cooling system, maintaining a stable speed of 2.5km/h at maximum pull force, with a maximum speed of 5km/h, balancing efficiency and tension consistency. Powered by Cummins engine and German Rexroth hydraulic components, the equipment meets long-term heavy-duty construction requirements for 220kV and 500kV lines, supporting Vietnam’s power grid upgrade with reliable machinery.
