What are Encapsulated Transformers and where are they used?

Encapsulated units are covered in a thicker coating of insulation than typical. Often the coils are completely encased in epoxy or an epoxy and aggregate mixture. Sometimes they are referred to as “potted” or “cast coil”.

The encapsulated design is especially suited for installations in harsh environments where dust, lint, moisture and corrosive contaminants are present. Typical applications include: pulp and paper plants; steel mills; food processing plants; breweries; mines; marine and shipboard installations.
