Class F PET Insulation Coaming Board for Dry Type Transformer Winding
Our PET insulation coaming board is made of high-performance biaxially oriented PET polyester film via composite hot pressing, Class F thermal resistance (155℃). It serves as core inner insulation support for windings of dry-type transformers, reactors and electrical motors, widely replacing traditional insulation paper with better insulation stability and longer service life, complying with IEC & GB electrical insulation standards.
