Anti-vibration system

SanerVib anti-vibration pads for electrical transformers

When electric transformers with dielectric oil or coated dry are in operation, they emit a characteristic noise resulting from the vibrations of the magnetic sheets (mageto constriction) which they contain. This vibration comes from the 50 Hz alternating current that runs through them, characterizing a fundamental vibration frequency of 100 Hz and several corresponding vibration harmonics.

In order to dampen its vibrations, we suggest using shock absorbers from the SanerVib range between the support supports of the transformers (feet, beams, wheels, etc.) and the ground. These are several low-frequency silentblocks specially developed to provide high anti-vibration performance at transformer excitation frequencies, depending on their weight and the desired attenuation.

The SanerVib must be chosen precisely so that the internal damping elements are neither too much nor too little compressed, thus fulfilling thei function to the full. SanerVib are available in 2 vibration absorption levels (up to 80% and up to 99%).

They can be configured according to 3 types of use :

  • SanerVib : for transformers with wheels,
  • SanerVib-SG : to equip a transformer without wheel,
  • SanerVib-VibeR or SanerVib-SL : to equip a "rolling" transformer.
