Encapsulated Transformer
Encapsulated transformers, potential transformers, flyback transformers or any one of a large number of specialized transformers in use today all perform the same basic function: to lower the voltage of a given electrical circuit.
PRODUCT DESCRIPTION
Encapsulated Power Transformers
Encapsulated (Potted) power Transformers (also referred to as Epoxy Resin Encapsulated) are designed for applications where the environmental conditions would not permit a general purpose ventilated dry type transformer. The entire transformer core & coil is encased in a silica sand / polyurethane mixture which protects the windings from any airborne contaminants and moisture.
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.

Benefits of Encapsulated Power Transformers
1. Mixture of silica sand resin forming a solid mass completely encloses and protects the core and coil, also significantly reduces audible noise.
2. Windings utilize Class 220°C Insulating rated for 150°C Rise, but designed to operate at 115°C maximum.
3. The transformer's core is solidly grounded.
4. Enclosure constructed from heavy gauge steel, coated with ASA#61 grey powder paint
5. Suitable for NEMA/CSA Type 3R and Type 4 Enclosure applications for both indoor and outdoor
6. Spacious wiring compartment, cool and easily accessible (bottom or front access may depend on size)
Applications of Encapsulated Power Transformers
1. For all general loads, indoors or out, including lighting, industrial and commercial applications
2. Units may be banked for 3-Phase operations
3. Corrosive Environments: Petro-Chemical, steel, pulp and paper industries
4. Damp conditions: Mines, pump-houses underground or rooftop service areas
5. Industrial applications: processes with high degree of airborne dust or conductive particles
