Vibration Damper, Stockbridge

Brand:

FARGO

Catalog ID:

6072025

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 dyanmic response that protects the conductor through the entire range of dangerous vibration frequencies.

  • Conductor/Cable Diameter Range 1.940 - 2.560 in (49.3 - 65.0mm)
  • Clamp Bolt Torque 40 ft-lb
  • To specify Torque Head/Break Away bolt option, add suffix “O” to catalog number.
  • Galvanized steel messenger cable
  • Weights are given a corrosion-resistant finish and have smooth surfaces and rounded edges to eliminate possible corona discharge.
  • The bolted clamp permits easy installation on a wide range of conductor sizes. Aluminum clamping bolt ensure that damper clamp remains tight as conductor temperature changes with current load cycling.
