company news about Efficient Flat Ground & Stable Mountain Construction: Hydraulic Puller-Tensioner in Vietnam

Vietnam’s power infrastructure projects cover plains, hills, and mountainous areas. Traditional stringing equipment can hardly meet both high efficiency in flat terrain and high stability in mountains. Hydraulic puller and tensioner adopt closed hydraulic circuit and automatic pull retention system, which can stably maintain preset tension even when speed drops to 0, and automatically adapt to terrain slope, cable friction and sudden load changes. The equipment supports 220kV/500kV high-voltage lines, OPGW/ADSS optical cables and various bundle conductors traction. It runs efficiently at 5km/h on flat ground and keeps stable at 2.5km/h in mountains to ensure tension consistency, balancing construction efficiency and safety, making it the mainstream choice for all-terrain transmission line construction in Vietnam.
