Cast resin power transformers

Transformer is completely sealed with epoxy.  A mixture of silica sand resin forming a solid mass completely encloses and protects the core and coil. Potting is done under vacuum. The еnclosure is constructed from heavy gauge steel.

Application:

In pulp and paper plants, steel mills, petrochemical plants, food processing facilities, breweries, mines, marine and shipboard installation.

Advantages:

• Physical protection of the windings, core, and lead connections makes the encapsulated transformers a clear choice whenever moisture, dust, dirt or other environmental threats are an issue.
• Encapsulation also has a strong impact on thermal and electrical performance. The epoxy compound used for potting has a high coefficient of thermal conductivity and is very effective at dissipating heat away from the windings and core. This thermal management reduces winding temperature differentials and allows the transformers to be used in higher ambient temperature environments.
• The epoxy encapsulated increases electrical insulation reliability.
