Electrical Flexible Laminates are made of 2 layers or 3 layers or multilayer of electrical insulation materials bonded with hi-temp resins. There are all kinds of laminates available from thermal class E to class H. Following table lists the nominal structures.
Excellent Electrical Insulation
Flexible and Easy Operation
Slot, Layer and Phase Insulation in Motors, Transformers and Generators
Interlayer Insulation in Choke Coils and Dry-type Transformers
