CLASS F DMD

Class F Epoxy Prepreg for dry type transformer

Product Specification

Class F Epoxy Prepreg used in dry type transformer is made of polyester film polyester fiber non-woven soft composite material impregnated with heat-resistance epoxy resin through baking.

 Feature and Application

The solidified materials have high mechanical strength, outstanding dielectric properties and adhesive properties, heat resistance grade is Class F.
It is applicable to the layer insulation and end insulation of Class F dry type transformers coils or electric reactor, as well as the layer insulation, slot insulation and turn to turn insulation of electrical machinery and electric appliance.
