ABSTRACT:
A vibration damper comprising a resilient messenger cable having a clamp intermediate its ends for securing it to a conductor. The cable has a weight secured to each end thereof, the center of gravity of each of the weights being disposed away from the axis of the cable. Each of the weights comprises an enlarged head portion attached to the ends of the cable, an arm extending from the head portion in a generally inward direction and a further mass supported at the distal end of the arm, the further mass being smaller in size and weight than the head portion. The size and placement of the further mass produces substantial local flexing of the messenger cable adjacent the innermost point of contact of the cable with the weight when the weight oscillates about its center of gravity.
