Vibration Damper, Stockbridge
Brand: FARGO
Catalog ID: 6071012O
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 0.859 - 1.130 in (21.8 - 28.7mm)
- Clamp Bolt Torque 25 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.
