ABSTRACT:
A high voltage outdoor power line includes at least one stranded conductor, and at least one damping device for damping mechanical Karman vibrations of the stranded conductor. The damping device includes a plurality of vibration dampers mounted on the stranded conductor by being suspended from respective suspension points on the stranded conductor, a spacing between the suspension points of two directly adjacent vibration dampers in a mounted state being smaller than half of a smallest anticipated wavelength of the Karman vibrations.
