Type No.:MAG-Vibration damper 4R stockbridge FR Damper
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.
