GPO3 UPGM203

UPGM203 (GPO3) is a rigid insulating material manufactured from alkali-free fiberglass mat impregnated with unsaturated polyester resin. By adding relevant chemical agents during the heating and pressing process, this material achieves exceptional performance for demanding environments.

Key Characteristics

• Maintains good electrical properties under high humidity conditions.

• Delivers high mechanical properties under medium temperatures.

• Features fine flame retardant properties, alongside excellent arc and tracking resistance.

• Conforms to EN 45545 R22/23 HL3 (approved by a professional European lab) and complies with UL94-V0 applications (certified by UL LAB).

Industrial Applications GPO3 is widely utilized in medium and low voltage electrical industries. Common applications include:

• Phase and end barriers

• Insulating supports

• Bus bar supports

• Mounting panels in switch-gears and other electrical apparatus
