Vibration control and compressed layer damping

Noise reduction in transformers & reactors through decoupling and isolation

Power equipment noise emissions have become significant contributors to urban noise pollution, Amorim’s solutions are cork rubber based elastomeric materials specially blended with the adequate quantity of cork granules and rubber blends to enhance energy dissipation and isolation, hence reducing structural borne noise in power equipment

Cork plays a significant role in the elastomer and is directly responsible for the damping function, commonly designated as the energy loss factor, while the rubber matrix takes care of the isolation, together they are the ideal combination when considering vibration and noise reduction solutions especially at resonance frequencies.

 The elastomeric blend is distinctive to rubbers which are incompressible, needing space to displace the compressed volume, cork rubber displaces much less volume due to corks compression within itself allowing for a wider tolerance in part shape and dimensions commonly designated as the shape factor, which in turn affects the design robustness.

  • Internal noise control treatments

    Amorim VC2100 vibration control material is especially used in power transformers and reactors as vibration pads beneath the active part immersed in oil, as well as decoupling supports between the core structure and the tank wall or tank cover on the core clamping mechanism. It can also be implemented for structural damping between the tank/shunt wall interfaces as a compressed layer damper. VC2100 appropriately applied is able to reduce up to 6dB in overall transformer noise.

  • External noise control treatment

    A number of different options are available to the power industry for external vibration pad materials. The VC6400 power grade formulated for longevity in outdoor environments and designed to withstand conditions such as the presence of Ozone/UV and extreme temperatures is very popular in large power transformers, whilst lower demanding loads in smaller power equipment, while equally important to provide noise reduction and vibration transmission within buildings the VC5200, VC1047 and VC1001 are extensively used.
