What’s GPO-3 material?

GPO-3 material is a mineral filled, continuous strand fiberglass-mat-reinforced thermoset unsaturated polyester material.GPO-3 laminate performs well in electrical applications including flame, arc, and track resistance.

Features of GPO-3:

1. Flame resistance: Because GPO-3 is made of halogen-free materials, when a fire occurs, it has good flame resistance and does not produce toxic gases.

2. Good mechanical properties: Because the main material of GPO-3 is high-strength glass fiber, it is not prone to chipping, and it is easy to bend to a diameter of 19mm

3. Simple production and easy forming: GPO-3 insulation material is simple and convenient to process, which can be punched, drilled, machined, cut and frosted

4. High temperature resistance: Because of the special properties of the material, GPO-3 can have UL temperature ratings within the range of 120-210°C electronics and 130-210°C mechanical. Has a strong stable performance.

5. Good insulation performance: It has high-quality insulation materials and is widely used in the electrical industry.

Application of GPO-3:

1. GPO-3 is widely used in circuit breakers, frame type circuit breakers: there are many applications in safety shutters, safety shutters, spacers, phase spacers, etc.; applications in molded case circuit breakers: Components such as phase partition plate and arc extinguishing chamber arc partition plate have applications;

2. GPO-3 is widely used in motors, such as motor armature parts, movable cover plates, slot wedge stators, fixed washers, thin washers, etc.

3. GPO-3 is widely used in various switchgears, and is used at the front, back, upper, low, and the same partitions in the partition system;

4. GPO-3 is widely used in various switch cabinets, such as partitions, liners, arc extinguishing hoods, arc extinguishing cylinders, arc extinguishing pieces, etc.;

5. GPO-3 is widely used in AC contactors; explosion-proof electrical appliances and other low-voltage electrical insulation partitions, etc.

In recent years, the development of insulating materials can be described as rapid progress, and the sales volume of GPO-3 is particularly prominent in the market.
