Epoxy pre-preg NPN(SHS)
Product Description
The heat-resistant SHS pre-preg is composition of polyimide mylar, heat-resistant insulating paper and flexible composite material with impregnation of hi-temp resistant epoxy resin(Class H) produced by baking.
Characteristics and Applications
The product is Class H insulating material with a high mechanical strength, excellent dielectric and adhesive capability.
The product is winding directly onto the conductor to form a secure insulation layer by heat curing. It is simple and convenient to use.
Capable for Dry-type transformer coil insulation layer, side insulation, motor slot insulation and inter-turn insulation.
