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.
SanerVib for wheels
Stainless steel anti-vibration pads adapted to the wheels of electrical transformers capable of reducing from 80% to 99% of the vibrations transmitted to the ground.
Stainless steel vibration reducer for electric transformers without a rolling system capable of reducing 80% to 99% of the vibrations transmitted to the ground.
Vibration absorber for "rolling" electrical transformers capable of absorbing 99% of the vibrations generated.
Available as a simple or double unit consisting of 1 more shock absorber elements :
- VibeR99 simple : damper with a screw through to attach directly to the transformers beal or U-profile,
- VibeR99 double : one hole is centred on the top plate to fix the damper to the beam and a second hole centred on the bottom plate to fix the wheel with a screw.
Anti-vibration cushion for "rolling" electrical transformers capable fo absorbing 80% of the vibrations emitted. Specially designed with a rolling track to facilitate the installation of transformers.
