Product Overview

The Vibration Damper (4D, FD, and FR Series Stockbridge Damper) is an essential anti-vibration fitting used in high-voltage overhead transmission lines, distribution networks, and OPGW/ADSS optical fiber installations. Manufactured by YiHao Power, these dampers are installed near line suspension clamps to absorb dynamic energy generated by laminar wind flows, safeguarding conductor strands from fatigue failure and extending line service life.
