SANERVIB-99 99% Anti-vibration mounts for transformers with wheels

Description

When electric transformers are in operation, they emit a characteristic noise resulting from the vibrations of the magnetic 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 SanerVib 99 series is designed to provide up to 99% vibration reduction.

Description of the SanerVib^® range 99:

• Classic 4-support configuration
• Consisting of one or more cores with a high-strength metal spring and a stainless steel fibre cushion at its core.
• 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 SanerVib80s 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 SanerVib^® 99 references are sufficient to cover most ranges of electrical distribution transformers up to 7 tonnes. These solutions can be adapted to 40 or 70 mm rollers.
