Product Information

Specification

Also known as:

Dry Type Transformers, Class F Insulation Transformers, Epoxy Encapsulated Transformers, Class F Dry Type Transformers.

About:

Transformers for solar applications with dry-type insulation can be of the Low-Low or medium voltage type with their windings encapsulated in epoxy resin through an injection process under vacuum conditions, which guarantees a minimum level of partial
discharges and makes them very reliable and maintenance free.
