company news about Hydraulic Puller and Tensioner Adapt to Mountain and Flat Terrain for Vietnam Transmission Line Construction

With the ongoing development of Vietnam’s power grid, the mixed terrain of mountains, hills and flat areas has brought challenges of stability and adaptability to transmission line stringing. Hydraulic puller and tensioner adopt closed hydraulic circuit to realize bi-directional stepless speed regulation, equipped with pull force pre-set system that maintains set tension even when speed drops to 0, automatically adjusting to on-site friction and sudden loads. The equipment supports 220kV/500kV line construction and can be used for stringing OPGW, ADSS optical cables and various bundle conductors, providing stable tension output and continuous operation in all-terrain transmission projects in Vietnam.
