Vibration and Spacer Dampers for Transmission Lines

Our vibration and spacer dampers are engineered to protect transmission line conductors from fatigue, galloping and wind-induced vibration. With manufacturing experience dating back to 1959 and supply to more than 45 countries, we deliver proven solutions that extend conductor life and improve system reliability across a wide range of voltage classes.

The product range includes Stockbridge dampers, spacer dampers, spacer-damper assemblies for bundled conductors and custom-engineered designs for long spans and high wind zones. Each unit is designed for efficient energy dissipation, stable clamp grip, corrosion resistance and long-term mechanical performance. All dampers are tested for frequency response, fatigue resistance and compatibility with ACSR, AAAC and HTLS conductors in accordance with international standards.

Utilities and EPC contractors rely on our vibration and spacer dampers to reduce maintenance needs, prevent conductor failures and enhance the operational stability of transmission lines in challenging terrain and climate conditions.
