A Stockbridge damper Simply because power lines can put up with aeroelastic flutter driven by wind, Stockbridge dampers will often be attached towards the lines to lessen the vibrations.
Insulators are broadly categorized as possibly pin-sort, which assistance the conductor previously mentioned the construction, or suspension sort, in which the conductor hangs down below the composition. The invention with the strain insulator was a critical factor in enabling greater voltages for use.
