Halogen Free High Strength GPO3 UPGM203 Laminated Sheet

High strength of laminated sheet GPO-3(UPGM203) with certificate of ROHS/REACH/UL

GPO-3 laminate sheet also known as UPGM 203, NEMA standard on North America , it is known as GPO-3 ; IEC Standard on Europe , it is known as UPGM203 , they are the same material . 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. So , it is composited on glass fiber mat and polyester resin , 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.

This material has been exporting to more than 30 countries all over the world , it covered new energy , rail traffic , power transmission and transformation .

Feature of GPO-3

High arc resistance and leakage resistance , flame retardant , it meets requirement for UL94-V0

High temperature resistance , can work continuosly at 155℃ on every electrical equipment .

Waterproof , it has propertiy on very low water absorption

Good electrical performance under high humidity due to low water absorption

It is green products with very little bit effect on environment , nontoxicity for human .

It is halogen-free material

Application

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.

GPO-3 laminate sheet performs well in electrical applications that require high arc and carbon track resistance as well as flame resistance, physical strength, and moderate heat resistance. Grade GPO-3 laminate 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.
