GPO-3 sheet is also called UPGM203 plate (Unsatured Polyester Glass Mat Plate). UPGM203 is IEC standard and GPO-3 is NEMA grade. It is kind of rigid plate insulating material, made of alkali-free fiberglass mat impregnated with unsaturated polyester resin, adding relevant chemical agents in heating and pressing to cure into rigid plate.
Standard Color: Red Color, White color
Raw Material: Glass Mat + Unsaturated Polyester Resin
Strong and stiff
Good flame and smoke characteristics
Impact resistant and Dimensional stability
Excellent electrical properties( under high humidity)
Good arc resistance and tracking resistance
GPO-3 glass reinforced thermoset polyester sheets, also known as “Red Barrier Board” in construction applications.
GPO-3 laminate performs well in electrical applications that require high arc and carbon track resistance as well as flame resistance, physical strength, and moderate heat resistance.
GPO-3 laminate 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.
GPO-3 is a UL recognized product with a temperature index of 120 degrees celsius electrical and 140 degrees celsius mechanical, and is molded in thicknesses of 1/32″ (.031″) to 2.00″ thick.
