Encapsulated transformers include transformers that are enclosed in a casing or coating. Transformers are encapsulated to protect components from contaminants present in the working environment, such as moisture, gases, dust, or dirt. They may also be encapsulated to meet spark-resistance requirements (for use near potentially explosive gases for example).
In addition to environmental protection, encapsulation can also dissipate heat from the core and windings, reducing temperature differentials around the windings and enabling the transformer to perform reliably in higher-temperature environments.
Encapsulated transformers are often used in the most demanding environments, and they can include almost any transformer type.
Sun Transformer can design and manufacture encapsulated transformers to meet nearly any requirement. For more information about how we can provide your transformer needs, please send us your specifications or call us today!
