Class H GHG is semi-solidify lining pre-impregnating materials that is made by combing polyimide film and non-alkali glassfiber cloth , and then baking after impernating class H heat-resistant resin. It has good flexibility , mechanical strength. Its heat expansion coefficient and dielectric constant are near to that of copper foil. It can be used as winding insulation for class F/H dry type transformers , end insulation and liners insulation for electric machinery.
