The DOGBONE Vibration Damper is designed to eliminate overhead shield wire fatigue damage and line maintenance costs by effectively diminishing aeolian vibration. The messenger cable and unique "dog bone" shape of the weights are designed to achieve optimal energy dissipation for minimal cable movement. The DOGBONE Vibration Damper may be used as an alternative to the Spiral Vibration Damper for customers who prefer a tuned damper option.

  • Offset dogbone-shaped weights introduce a torsional mode of vibration damping not present in conventional Stockbridge type dampers

  • Galvanized 19-strand messenger cable provides greater energy dissipation at small amplitudes of cable motion

  • Damper attachment clamp provides adequate slip strength without imposing excessive clamping pressure on the conductor

  • Capable of being installed by hand or using live line installation techniques without the need to disassemble the clamp
