Vibration Damper for Overhead Power Lines | Anti-Vibration, Corrosion-Resistant

Vibration Damper

Product Description：

The Vibration Damper for Overhead Power Lines is engineered to control wind-induced vibrations and protect conductors, ground wires, and fittings from fatigue damage. Made from corrosion-resistant materials with balanced counterweights, the damper efficiently dissipates vibration energy from aeolian, subspan, and galloping motions. It ensures long-term network reliability in HV and MV transmission systems.

Product Advantages：

1. Excellent vibration-damping performance for long spans

2. Corrosion-resistant weights and galvanized steel messenger wire

3. Extends service life of conductors and fittings

4. Stable damping effect across a wide frequency range

5. Suitable for MV/HV transmission and sub-transmission lines

6. Easy installation, strong mechanical reliability
   

Application Scenarios：

1. Long-Span Transmission Lines：Installed near suspension clamps to absorb wind-induced vibration in long spans.

2. Sub-Transmission & MV Networks：Placed at calculated positions according to span length to prevent aeolian vibration.

3. Coastal or Corrosive Environments：Corrosion-resistant components maintain damping stability under salt fog exposure.

4. Lines with High-Tension Conductors：Protects fittings and strands from fatigue failure due to repeated small-amplitude vibration.

5.  Mountainous and High-Wind Areas：Reduces conductor fatigue caused by continuous wind pressure and turbulence.

Quality Assurance：

Each damper is tested for frequency response, damping ratio, mechanical tensile strength, corrosion resistance, and fatigue performance according to ASTM standards.
