Product Details

FR vibration dampers effectively prevent fatigue damage to conductor and static wires caused by wind-induced Aeolian vibration.


The FR 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 FR.


These additional resonant peaks create an envelope of dynamic response that protects the conductor through the entire range of dangerous vibration frequencies.
