Cast-resin Transformer
Cast-resin transformers mainly consist of core and windings. The winding of this type of transformer is not immersed in insulating oil, but is encased in epoxy resin that helps protect the transformer from dust and corrosive atmospheres. Because no oil is used, cast-resin transformers are generally simpler to install and require no fire-proof vault for indoor installations.
Standards
Estel’s cast-resin transformers are designed and tested according to IEC60076 or as specified by customers.
