Class H NHN Epoxy prepreg for dry type transformer

Product Specification

Class H NHN prepreg used in dry type transformer is made of polyimide film aromatic polyamide paper soft composite material impregnated with class H epoxy resin through baking.

 Performance and Application

The solidified materials have high mechanical strength, outstanding dielectric properties and adhesive properties. Heat resistance grade is Class H.
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.
