Vibration Damper

Fargo® 4-R stockbridge vibration dampers effectively prevent fatigue damage to conductor and static wires caused by wind-induced aeolian vibration. The 4-R concept improves on the design of the basic Stockbridge Damper, significantly increasing the efficiency of converting wind-induced energy into heat. The improved design employs unequal weights on messengers of unequal length. This configuration doubles the number of resonant peaks from two generated by the old-style Stockbridge Damper to four in the improved Fargo® 4-R. These additional resonant peaks create an envelope of dynamic response that protects the conductor through the entire range of dangerous vibration frequencies.
  • Messenger Cable: Materials and stranding are selected to obtain the best energy absorption characteristics. The galvanized steel messenger is manufactured to rigid engineering standards.
  • Clamp: The bolted clamp permits easy installation on a wide range of conductor sizes. Aluminum clamping bolt ensures that damper clamp remains tight as conductor temperature changes with current load cycling.
  • Weights: Uniquely s
