Polyester Glass (GPO3)
A specially engineered fiberglass reinforced thermoset polyester composite. With excellent dielectric, thermal, corrosion and structural properties.
Meets NEMA GPO3, UPGM203, NFF16-101(Rolling Stock)
Recognised as a top performer in the electrical industry. Retains electrical properties without adverse effects to product strength and stability at elevated temperatures. Typical applications include general purpose electrical insulation, transformer spacers and supports, transportation components, high voltage appliance insulators, bus bar supports and switchgear.
Meets NEMA GPO3
A high performance electrical insulating material. Exceeds NEMA in dielectric strength, arc resistance and tracking resistance. Highly flame retardant and low smoke generating. Applications include high voltage appliance insulators, bus bar supports and barriers in switchgear.
Meets NEMA LI-1 GPO3, UPGM 203, DIN 7735 HM2471
Excellent electrical insulation properties. Tracking resistance up to CTI 600. The most modern SMC press system allows for a sheet thickness of 130mm with a tolerance of ±0.1mm. A sheet length of up to 3720mm. Typical applications include the transformer, rail, switchgear and high-voltage industries
