Micapact insulation

The main constituents of the new insulation are mica paper, which acts as the predominent dielectric, glass fibre as backing and a modified epoxy resin as bond. The excellent properties of the new insulation show that the adoption of these modern materials as well as of suitable process techniques has enabled the objectivities of the development work to be attained. The use of glass fibre in the place of paper or silk as backing and a heat-curing epoxy resin impregnant instead of a thermoplastic such as asphalt permits a higher service temperature.
