In principle it is impossible to avoid wind – induced conductor vibrations on overhead lines. In the most unfavourable cases, fractures caused by vibrations on accessories and overhead lines can already occur directly after installation on the overhead line. However, fatigue fractures caused by continuous vibration may occur only some years after installation.

Stockbridge dampers for single conductors and spacers dampers for bundle conductors, have been used for the purpose of reducing the intensity of vibrations. Various types of wind – induced mechanical oscillations occur on overhead lines.
