Helical Vibration Damper for Conductor

Helical Vibration Damper for Conductor

The Vibration Damper is to provide the best possible protection from aeolian vibration for conductors and earth wires (including OPGW). It is used for electric power transmission and distribution.

Usage scenarios

Transmission lines system, distribution system

Technical features

  1. Vibration dampers are to dissipate the maximum amount of vibration energy to prevent fatigue damage to the strands of the conductors;
  2. Vibration Damper has an asymmetric design that features 4 resonant frequencies.

Product advantages

  1. Computer simulation software TIII. This computer model identifies the optimum damper placement on the span whose development has been verified by decades of testing and field measurements.
  2. We can do all types of tests for vibration damper according to IEC 61897, AS 1154.1, etc. test standards, even damper effectiveness evaluation tests for large spans.
  3. This design can avoid stress concentration, and it is suitable for stress-sensitive conductors.
