GHG Pre-impregnated Material
It is made of polyimide film bonded with non-alkali fiberglass cloth on both sides, then impregnated with H class heat-resistant resin and last baked into half-solid shape. It is a reliable adhesive, and the thermal class is H.
Characteristics
Flexible, not easy to break, can be use at any angle
Long time of storage, simple molding technology
Special glass component, heat expand modulus is close to copper foil
Trade with coupling agent on surface, no delaminating inner, high mechanical strength
Storage
The products should be put into carton after sealed with plastic pocket, of which the weight is no less than 60kg. It should storage under the dry, well-ventilated, room temperature. It should be care of fire-proof, moisture-proof, compression-proof and sun-proof and sun-proof, the time of storage is more than 6 month
Application
Used as slot insulation, phase insulation, liner insulation, layer-pressure insulation and other special insulation of class F or class H dry type transformer
