DOGBONE® Vibration Damper for Tower Down Guys
The DOGBONE Vibration Damper for Tower Down Guys is designed to eliminate guy line fatigue damage and line maintenance costs by effectively diminishing aeolian vibration. The messenger cable and unique "dog bone" shape of the masses are designed to achieve optimal energy dissipation for minimal clamp movement.

-
Messenger Cable – The 19 strand messenger cable provides greater energy dissipation at small amplitudes of flexure.
-
Damper Attachment Clamp – Provides adequate slip strength without imposing excessive clamping pressure on the conductor.
-
The offset "dog bone" shaped masses also introduce a torsional mode of vibration damping not present in conventional Stockbridge type dampers
-
Can be installed by hand or by using live line installation techniques without disassembling the clamp.
