ABSTRACT:
A vibration absorber for attachment to suspended cables such as electrical transmission lines, to suppress vertical aeolian vibrations as well as horizontal sub-conductor oscillations. A clamp arm has one end attached to a suspended cable and a fulcrum adjacent the other end. The fulcrum is rotatably coupled to a frame, and the end of the clamp arm adjacent the fulcrum is coupled to the frame through the air cylinder damping element which forces air through a small orifice to provide viscous damping when the clamp arm is caused to rotate relative to the frame as a result of said vibrations or oscillations. A pair of torsion springs or non-rotatably mounted resilient washers acts to restore the initial orientation of the clamp arm.
