Product Description

Product Description

 

H-Class Epoxy Prepreg used in dry type transformer is made of polyimide filmpolyester fiber non-woven soft composite material impregnated with class Hheat-resistance epoxy resin through baking.
The solidified materials have high mechanical strength,outstanding dielectricproperties and adhesive properties. Heat resistance grade is Class H.
Product is wound in the conductor directly, can form a strong insulation layer afterthermo curing, and the process is simple and convenience.
It is applicable to the coil layer insulation and end insulation of Class H dry typetransformer or electric reactor or mining transformer, as well as the layer insulation,slot insulation and turn-to-turn insulation of electrical machinery and electricappliance
