ABSTRACT:
A vibration absorber for attachment to suspended cables such as electrical transmission lines, to suppress vertical aeolian vibrations as well as horizontal subconductor oscillations. A clamp arm has one end attached to a suspended cable and another end rotatably coupled to a frame through two frictionally-engaged elements which provide coulomb friction when the clamp arm is caused to rotate relative to the frame as a result of said vibrations or oscillations. A separate resilient member couples the clamp arm to the frame to restore the initial orientation of the clamp arm.
