Why is GPO-3 material being increasingly widely used?

GPO-3, also known as UPGM-203, refers to unsaturated polyester glass fiber mat laminhttps://www.rdscomposites.com/gpo3-profileate material. It is typically red, white, or reddish-brown in color, exhibits excellent electrical properties at high temperatures, good mechanical performance at moderate temperatures, and possesses flame retardancy, arc resistance, and superior tracking resistance. As an excellent insulating material, GPO-3 is widely used in mechanical and electrical industries.

So, what are its outstanding product characteristics?

1. Flame retardant: Since GPO-3 insulating material contains no halogens, it demonstrates strong flame retardancy in case of fire without releasing toxic gases.
2. Excellent mechanical properties: Made primarily from high-strength glass fibers, GPO-3 is resistant to cracking and can be easily bent to a diameter of 19mm.
3. High-temperature resistance: Due to the special properties of its composition, GPO-3 has UL temperature ratings for electronics (120-210°C) and mechanical applications (130-210°C), ensuring exceptional stability.
4. Superior insulation performance: As a high-quality insulating material, it is extensively utilized in the electrical industry.
5. Easy fabrication and formability: GPO-3 insulating material is simple to process, allowing for punching, drilling, machining, shearing, and sanding.
6. Cost-effectiveness: It is relatively low-cost, easy to package, transport, and store, and can be stored at room temperature for extended periods.

In recent years, the power industry has actively developed new materials with flame retardancy, insect resistance, wear resistance, non-corrosiveness, and high dimensional stability. Leveraging its insulation advantages, GPO-3 laminates find applications in low-voltage electrical equipment or automotive industries, such as circuit breakers, switchgear, transformers, DC motors, AC contactors, and explosion-proof electrical devices.

1. Application in circuit breakers: Frame circuit breakers: Safety barriers, protective covers, spacer pads, phase barriers, etc.
2. Application in molded case circuit breakers: Phase barriers, arc chute plates, etc.
3. Application in clectric motors: Motor armature components, movable covers, stator slot wedges, shims, thin spacers, brush holders, etc.
4. Application in switchgear: Front, rear, top, bottom, and phase barriers in partition systems.
5. Other arc-resistant structural components.
