In the field of electrical insulation materials, GPO-3 sheets have become essential components in many critical systems due to their unique performance advantages. GPO-3 sheet manufacturers emphasize strong arc resistance and thermal stability as their core strengths, delivering reliable insulation solutions for the power, transportation, and industrial sectors.
GPO-3 sheets exhibit excellent arc resistance. In high-voltage arc environments, they maintain structural integrity over prolonged periods, effectively withstanding arc-induced damage. This makes them ideal for use in high-voltage switchgear, circuit breakers, and other arc-prone electrical equipment—greatly enhancing operational safety and reliability, and safeguarding the stable operation of power systems.
GPO-3 also stands out for its superb tracking resistance, with a high Comparative Tracking Index (CTI) that ensures dependable insulation even in humid or contaminated environments. This significantly reduces the risk of electrical leakage-related hazards, making it suitable for applications with stringent electrical safety requirements.
GPO-3 sheets exhibit exceptional thermal performance, maintaining stability and structural integrity even in prolonged high-temperature environments. With a heat resistance rating of Class F, and even higher temperature tolerance for premium models, they provide reliable insulation protection for high-temperature equipment such as motors and industrial furnaces.
GPO-3 sheets meet the UL 94 V-0 flammability standard, demonstrating top-tier flame-retardant performance. When exposed to fire, the material self-extinguishes quickly after the ignition source is removed, with no dripping. This significantly helps prevent the spread of flames in the event of a fire, enhancing overall fire safety for both equipment and facilities.

Power Industry: GPO-3 is used as insulation and support components in high and low-voltage switchgear and transformers, ensuring safe and stable power system operation.
Transportation Sector: GPO-3 is ideal for electrical insulation parts in rail transit vehicles, offering dependable safety in transport electrification systems.
Industrial Equipment: GPO-3 plays a vital role in high-temperature insulation protection for motors, furnaces, and other equipment—supporting safe and efficient industrial operations.
Prioritize manufacturers that have obtained internationally recognized certifications, such as UL certification. These certifications are strong indicators that the products comply with strict safety standards, effectively reducing operational risks and ensuring product quality and safety.
Select products with appropriate arc resistance and thermal stability based on the specific requirements of your application scenario. For example, in high-temperature environments, GPO-3 sheets with higher heat resistance ratings should be preferred to ensure the long-term stable operation of equipment.
Choose manufacturers with strong customization capabilities. Such manufacturers can not only supply standard products but also provide customized production based on special specifications or profile needs, helping meet specific design requirements and offering greater flexibility and assurance for project execution.
