Description
GPO3 Polyester Glass Mat Laminate Sheet GPO3 CNC Machining Products for TransformerUPGM203 Sheet also known as GPO3, it is alkali-free fiberglass mat dipped into unsaturated polyester resin adding relevant chemical agent as the basic material pressed under high temperature molded into rigid panel as insulating material. It has good electrical property under high humidity and high mechanical property under medium temperature, fine fire retardant property, 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 and other types of electrical apparatus.
