GPO-3 / UPGM203 Polyester Glass Mat Laminate Sheet
Description:
GPO-3 Polyester Glass Mat Laminate Sheet is produced by combining polyester resin with glass mat and suitable in organic fillers and laminating under heat and pressure.
This laminate is in accordance with the following international standards:
NEMA LI-1: GPO-3, IEC60893 UP GM 203, DIN 7735 HM2471/ HM2472.
GPO-3 laminates sheet offers a superior combination of electrical and mechanical properties such as dielectric strength, flame resistance, high arc and carbon track resistance, moderate heat resistance and high-impact strength. It also exhibits good retention of properties and dimensional stability at elevated temperatures.
Application:
GPO-3 Laminate Sheet is used extensively in the making of phase and end barriers, insulating supports, bus bar supports and mounting panels in switchgear and other types of electrical apparatus
