Product introduction
GPO3 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.
In other way , it has fine fire retardant property and meet UL94-V0 with very low smoke , good arc resistance and tracking resistance (CTI600) , so this material has been widely used in rail traffic filed . The filler material of GPO-3 material is aluminium hydroxide , it is lower water absorption than calcium carbonate and better fire resistance . Lower absorption means better electrical performance .
Good arc resistance property means not easy to carbonization when impact by arc , as we known if the material is carbonization , insulating strength has been decreased . so it is the safety material. It's widely used in the low voltage electrical industries such as making of insulating sheet in UPS , top cover and bottom cover in transformer .
