SANERVIB-80-SL Vibration damper to 80% with rolling slope

0,00 €

Up to 80% vibration damping without lifting the transformer

SanerVib-80-SL is a range of anti-vibration mounts with a rolling slope for electric transformers with wheels, 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

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 80-SL series is designed to reduce vibrations by up to 80%.

 

Description of the SanerVib® 80-SL range:

  • Classic 4-support configuration
  • Stainless steel cushion
  • 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 SanerVib80-SL units 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 rolling slope makes it easy to position the transformer on the upper part, which supports the rollers. A pin is supplied to lock the wheel in the support, preventing any movement of the structure.

 

The SanerVib® 80 SL silentblock supports transformers up to 5.2 tonnes and can accommodate wheels up to Ø 100 x 45mm on its top plate.

Details of the SanerVib 80-SL (ref. SanerVib80-05200SL) : Length: 32.4 cm / Width: 10 cm / Height: 5.3 cm / Weight (set of 4): 12 kg

Accessories and options

The SanerVib® range is made up of several references depending on the support load, wheel dimensions, type of base plate, attenuation required, etc. Please contact us with the characteristics of your site and your requirements for the anti-vibration system.

Depending on the configuration of your project, the SanerVib® range is available in several versions:

  • For your transformers with wheels: SanerVib 80 range (80% reduction) SanerVib 99 range (99% reduction)
  • Instead of wheels, an anti-vibration pad can be fitted to your transformers: SanerVib 80-SG range (80% reduction) and SanerVib 99-SG range (99% reduction).
  • A system integrated into the rollers for your rolling electrical transformers that dampens 99% of vibrations: VibeR80 range
  • For special applications, contact us: SanerVib-SP range

Use and maintenance

Before installation:

It is essential to choose the right reference for your site, taking into account the width of your wheel (so that it fits into the upper support and cannot be moved) and the weight of your transformer (so as not to exceed the recommended compression range).

 

Installation:

4 M11 holes are used to fix each silentbloc to its mounting surface. Once the transformer has been rolled onto the SanerVib80-05200SL, a pin locks the wheel in the support, preventing it from rolling back.

 

Maintenance:

The treatment of SanerVib® has been reinforced, so unlike other solutions, they do not need to be replaced.

Refer to the user manual for further details.

The owner of the equipment is responsible for and liable for any failure to comply with good usage practices and for any failure to deal with anomalies and defects in the field.

Additional information

Storage facilities for high-voltage substations in contact with polluting products must comply with the standards and laws in force.

The SanerVib® range has been designed to isolate these vibrations generated by the magneto-constriction of transformers, and in particular its fundamental excitation frequency of 50 Hz and its harmonics of 100 to 200 Hz. All SanerVib® silentblocks have been tested in specialist SilentFlex® laboratories.
