Product Description
H class GHG Epoxy prepreg for dry type transformer
Product Specification
Class H GHG prepreg used in dry type transformer is made of polyimide film non-alkali glass cloth soft composite material impregnated with class H heat resistance epoxy resin through baking.
Feature and Application
With outstanding dielectric properties, adhesive properties and heat-resistant properties, it becomes a reliable heat bonded material after solidification, which is an ideal insulation material for H class transformer.
Product is wound in the conductor directly, can form a strong insulation layer after thermo curing, and the process is simple and convenience.
It is applicable to the coil layer insulation and end insulation of Class H dry type transformer or electric reactor, as well as the layer insulation, slot insulation and turn-to-turn insulation of electrical machinery and electric appliance.
