Product Information

Specification

Also known as:

Dry Type Transformer, Epoxy Encapsulated Transformer, Electrical Power Transformer, Class F Insulation Transformer.

About:

These transformers are designed for a type F thermal class, that is, they can withstand up to 155 °C. In addition, the fact that the internal dielectric materials of the windings are encapsulated and therefore are not in contact with the environment, makes these
transformers very durable equipment over time. These special characteristics make of encapsulated dry transformers highly reliable, safe equipment, with low operating and installation costs, minimum maintenance and minimum environmental impact.

Notes: This product can be customized as per customer requests.
