FIELD: transport engineering; power supply systems.
SUBSTANCE: invention relates to power supply lines in contact with vehicle current collectors. Proposed self-excited vibration damper contains carrying cable with weight attached to cable. Weight is made all metal, provided with through hole along horizontal axis in which bearing is arranged, being rigidly attached to carrying cable and to weight. Weight can be made in form of solid of revolution.
EFFECT: increased efficiency of vibration damping in contact system, increased service life of dampers.
