High Thermal-Resistant Gpo3 Fiberglass Sheet Insulation Material for Electrical Equipment

Product Description

Product Description

GPO3 Sheet

GPO-3 laminate sheet provides outstanding electrical insulation properties, maintaining stable performance under high humidity conditions and suitable for demanding electrical applications. Manufactured from alkali-free fiberglass mat reinforced with unsaturated polyester resin, GPO-3 offers excellent mechanical strength, rigidity, and dimensional stability. GPO-3 insulation board features good flame resistance, helping improve safety and reliability in electrical equipment. The material provides excellent resistance to electrical arc and leakage tracking, making it suitable for high-voltage electrical insulation applications. GPO-3 laminate is widely used for busbar supports, transformer insulation parts, switchgear components, motor insulation structures, and other electrical equipment. 

GPO3 fiberglass Laminated Sheet is made of high strength fiberglass mat impregnated with unsaturated resin paste, after heat molded compression and pultruded. 

Characters 

GPO3 has good electrical property under high humidity and high mechanical property under medium temperature, fire retardant property, good arc resistance and tracking resistance. 

Mechanical Strength: It can be machined, punched, drilled, milled, sawn, sanded, sheared or routed. Assembly by bonding, metal screws or rivets are also possible.

Application 

Ii is typically used in phase and end barriers, insulation support, bus bar support, mounting panels, transformers, antenna bases, and spacers. 

Specification
