FR damper Installation instructions for vibration dampers
1. Dampers shall be located from the center of the damper clamp
to either the dead end or the suspension supportas shown above.
2. The orientation of the damper weights along the conductor is
optional. For convenience, orient the damper such
that the clamp bolt head faces the installer.
3. When only one damper is required per conductor per span,
it can be installed at either span extremity when the
support hardware is identical. When support hardware differs,
place the damper at the suspension structure.
4. When two dampers are required per conductor per span,
the preferred placement is one at each span extremity.
