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 silent blocks 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 :
TECHNIKELEC® also offers anti-vibration plates (PAV) are made of nitrile rubber to reduce the propagation of noise caused by transformer vibrations. They absorb 40% to 60% of vibrations and are placed under the retention tanks to avoid its displacement.
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 :
Anti-vibration cushion for "rolling" electrical transformers capable to absorbing 80% of the vibrations emitted. Specially designed with a rolling track to facilitate the installation of transformers.
Nitrile rubber anti-vibration plates for retention tanks, capable of absorbing 40 to 60% of the vibrations of electrical transformers transmitted to the ground and absorbing shocks.
