Stockbridge Damper Vibration Suppression for Overhead Transmission Lines

Jiujin Electric Power’s Stockbridge Damper represents precision engineering for overhead transmission line protection. These dampers are specifically designed to mitigate aeolian vibration – high-frequency, low-amplitude oscillations caused by wind vortex shedding that can lead to conductor fatigue failure. Manufactured to international standards including IEC 61897 and DL/T 1099-2009, our dampers feature optimized mass-spring systems that dissipate vibrational energy through tuned counterweights connected by flexible steel strands. The robust construction ensures reliable performance in diverse environmental conditions, from coastal areas to industrial zones. Through careful parameter optimization including hammer mass, steel strand length, and moment of inertia, our dampers provide effective vibration control across multiple frequency ranges, protecting your transmission infrastructure and reducing maintenance costs.
