1. class H
2. with a high mechanical strength
3. excellent dielectric
4. good adhesive
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
Capable for Dry-type transformer coil insulation layer, side
insulation, motor slot insulation and inter-turn insulation.
The surface of pre-preg must be smooth, resin is evenly scattered.
No impurity can be found which would affect the performance of the
No folding mark, bubble, or corrugation when opening the pre-preg .
≤3,each in length of 10m and above.
The end of bundle is attached firmly with heat-resistance tape.
Standards of Supply
