Dry type transformer
HV windings of transformer coated with epoxy cast resin under vacuum. LV windings of transformer can be produced by both cast resin and resin impregnated prepreg method. They are produced in natural air cooled (AN) or fan cooled (AF) options in the 25-25000 kVA power range, up to 36 kV voltage level. It can provide up to 40% power increase by using cooling fan.
