--Two layers: polyester film is bonded with insulating paper.
--Base Layer: 100% Sulfate wood pulp presspaper
--Outer Layer: Polyester film(PET) for Electrical Purposes
Advantages :
-Outstanding dielectric properties
-Fish paper electrical insulation has good mechanical strength because it's fibrous
-Retains greater flexibility than plastics at low temperatures
