Product Description

Made in China GPO-3 laminated material recognized EN45545 and UL



Destripation of GPO-3 

GPO-3 also called UPGM203 , different standard of area with different name , but the same raw material . Material composition of it is glass fiber and polyester resin . It is alkali-free fiberglass mat coated with unsaturated polyester resin as the reinforce material , then pressed the sheet under high temperature into rigid sheet as insulation sheet. It has good electrical property under high humidity and high mechanical property under medium temperature , it has been used in so many electrical equipment current . In other way , it has fine fire retardant property and meet UL94-V0 , good arc resistance (arc resistance meet 184 second) and tracking resistance (CTI600) , good arc resistance property means no easy to carbonization when impact by arc , as we know 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 .
