ABSTRACT:
A vibration absorber for attachment to a single conductor suspended transmission line to suppress vertical aeolian vibrations. A clamp arm has one end attached to a suspended cable and another end rotatably coupled to a housing having a weight extending therefrom through two frictionally-engaged elements which provide coulomb friction when the clamp arm is caused to rotate relative to the housing as a result of said vibrations. A separate resilient member couples the clamp arm to the housing to restore the initial orientation of the clamp arm.
