Up to 80% vibration damping for electric transformers with wheels
VibeR-80 is a range of anti-vibration mounts that are completely integrated into the wheels of electrical transformers, reducing up to 80% of vibrations. These silentblocks have been developed to provide high anti-vibration performance at transformer excitation frequencies, depending on their weight.
Description
Description
When electric transformers are in operation, they emit a characteristic noise from the vibrations of the laminations they contain. This vibration comes from the 50 Hz alternating current that flows through them, which has a fundamental vibration frequency and several corresponding harmonics of vibration at 100 to 200 Hz. Depending on the load used, the design and the age of the transformer, these vibrations can increase over time. In addition, depending on the installation site, these vibrations may enter into resonance with the frame.
To dampen the noise generated by oil-filled or dry-coated electrical transformers when they are in operation, we have designed the SanerVib® range. This is a range of low-frequency silentblocks specially developed to provide high anti-vibration performance at transformer excitation frequencies. The VibeR-80 series is designed to reduce vibrations by up to 80%.
Description of the VibeR-80 range:
- Classic 4-support configuration
- Stainless steel damper spring
- Metal design with a modulus of plasticity that varies very little over time, unlike other plastic or elastomer solutions on the market, which have to be changed regularly.
- Reinforced surface treatment so that ageing is close to the life of the transformer.
- All VibeR99s are made of painted steel, category C2, with a superior anti-corrosion treatment (galvanisation or stainless steel on request).
- Midnight blue as standard, other colours available on request
The VibeR-80 is a silentblock specially designed to be integrated directly into the transformer, above the roller. Depending on the load to be supported, it consists of 1 or more damping elements:
- Single VibeR-80 up to 300 kg (ref. VibeR99-1200) and up to 750 kg (ref. VibeR99-3000)
- Double VibeR-80 from 500 to 1500 kg (ref. VibeR99-6000)
Details of the VibeR-80 range:
- VibeR-80-1200: Length: 8.8 cm / Width: 8.8 cm / Height: 12 cm / Weight (set of 4): 12 kg
- VibeR-80-3000: Length: 8.8 cm / Width: 8.8 cm / Height: 12 cm / Weight (set of 4): 14 kg
