It is created from electrical glass cloth with alkali-free that has been impregnated with diphenyl ether resin under pressure. Heat and rolling. The thermal grade is class H insulation. With excellent mechanical strength and dielectric property after in wet, self-extinguish, radiation-proof. Used for the insulating slots. windings. gaskets. junction boards of the dry-type transformer/mine transformer/motor/electrical equipment which are working at high temperature.
