GPO-3 laminate material,
High tensile strength GPO-3
GPO-3 is also called UPGM203, it is a glass mat reinforced thermoset polyester molded sheet, which is both arc and track resistant.GPO-3 is a UL recognized grade and is highly flame retardant and low-smoke generating. UPGM203 is widely used in Europe and GPO-3 used in North America . It has good electrical property under high humidity ,mechanical property under medium temperature, very nice on fire retardant property (it meet UL94-V0), good arc resistance and tracking resistance. It's widely used in the low voltage electrical industries such as making of phase and end barriers, insulating supports, bus bar supports and mounting panels in switch-gear ,UPS and other types of electrical apparatus.
pes of electrical apparatus.This material is more and more widely used in every medium voltage and low voltage electric
equipment due to excellent properties .
Feature of this material:
1.-- Very low hygrometric susceptibility.
2.-- Small losses at high frequency.
3.-- Excellent mechanical properties.
4.-- Good dielectric properties.
5.- High resistance to flame ( V-0)

Application of GPO-3 material
We are one of the most biggest UPGM203 manufacturer in China , laminate sheet and shapes were produced by our production line , so the material cost , quality and lead time can be controlled .
GPO-3 laminate sheet performs well in electrical applications that requires high arc and carbon track resistance as well as flame resistance, physical strength, and moderate heat resistance. GPO-3 material is used extensively in the making of phase and end barriers, insulating supports, bus bar supports and mounting panels in switch gear and other types of electrical apparatus. More and more electrical equipment manufacturer using it in high-voltage appliance insulators, bus bar supports, and barriers and mounting panels in switchgear, as well as other types of electrical applications.
