Select 4-R™ Fargo® 4-R Vibration Damper Application Software Instructions Select 4-R ™ is Hubbell Power Systems’ online software for the application of Fargo 4-R Stockbridge-type dampers to provide vibration protection of open-wire overhead power line conductors and shield wire cables. Damper recommendations are based on user-defined inputs of basic line design and operating environment data for specific line construction or reconductor projects. The vibration dampers recommended are designed to protect conductors and shield wire cables from bending strains associated with small-amplitude conductor motion known as aeolian vibration. Large-amplitude, low-frequency conductor/cable motion known as galloping is typically associated with uneven ice formation on conductors/cables and strong winds. Galloping can damage line components, including vibration dampers, and must be prevented by other measures which are the responsibility of the line designer to specify and implement. For additional information, visit our website at HubbellPowerSystems.com . Thank you for specifying Fargo 4-R dampers to provide aeolian vibration protection for conductors/cables on your power line projects.
