Abstract of the Disclosure A damping spacer for overhead conductors comprises at least two rigid spacing arms, with each arm having means for clamping the arms to respective conductors. Each arm is provided with an integral hub structure for holding a composite elastomer damping element, the hub structures and damping element being mechanically held together by a pin means extending through the hub structures and damping element. The damping element is comprised of an inner structure made of a relatively soft elas- tomer material and an outer structure made of a relatively hard elastomer material. The soft elastomer is effective to dampen low amplitude, high frequency aeolian vibration, while the rela- tively hard elastomer is effective to dampen high energy, wake- induced oscillations in a conductor bundle. The hard material also serves as a stop mechanism to limit relative motion of the arms and hub structures. This provides protection for the soft elastomer and prevents clashing of the metal parts of the spacer.
