The Pure Polyester Film (PET) Composite Insulating Barrier Board

The PET Composite Insulating Barrier Board is a rigid insulating material made by laminating and pressing two or more layers of electrical-grade polyester film with a special heat-resistant adhesive. It relies entirely on the composite structure of multiple PET film layers to provide the required mechanical strength and electrical insulation performance.
The product features a smooth and dense surface, is specifically designed for dry-type transformers and is particularly suitable for use as the main insulation between high-voltage and low-voltage coils. It is also widely used in the insulation of high-voltage electrical apparatus and motor windings.
