GPO-3

Gpo-3

This GPO-3 is a fiberglass reinforced thermoset polyester electrical grade sheet. This composite has an excellent combination of high strength, flame resistance and low smoke generation. This makes it ideal as a flame arc/track resistant electrical insulation.

Applications

This composite is ideal for flame arc/track resistant electrical insulation such as insulators, used as bus bar supports, transformer parts and switchgear insulators.
