Application and identification of GPO-3 board

Characteristics of GPO-3 board

1.Electrical performance: The GPO-3 board has the characteristics of good electrical performance under high humidity, arc resistance and leakage trace resistance, and its leakage resistance index can reach 600V.

2.Mechanical properties: At moderate temperatures, GPO-3 boards show good mechanical properties. The high-strength glass fiber reinforced polyester laminate material does not shatter and provides structural support.

3.Flame retardant performance: GPO-3 board is flame retardant, and the smoke and toxic smoke are very small when burning (especially Grade UTR grade materials do not contain halogens).

4.Machinability: These materials can be easily formed using standard metal handling equipment and can be pressed, drilled, machined, cut and frosted.

Specific applications of GPO-3 board

1. Application in circuit breakers

GPO-3 boards have a variety of applications in circuit breakers, including frame-type circuit breakers and molded case circuit breakers. In frame-type circuit breakers, GPO-3 board is used for safety baffles, safety shields, spacer pads, phase partitions, etc.; in molded case circuit breakers, it is used for phase partitions, arc-extinguishing chamber arc-isolating plates and other components.

2. Application in electric motors

In electric motors, GPO-3 board also plays an important role. It is often used for insulation treatment of motor armature components, movable cover plates, slot wedge stators, fixed gaskets, thin gaskets and carbon brush holders. The insulation performance of these components is crucial to the normal operation of electric motors. With its good heat resistance and electrical properties, GPO-3 board can ensure the stable operation of these components in high temperature and high load environments, thereby improving the reliability and service life of electric motors.

3. Application in switchgear

GPO-3 board is also widely used in switchgear. It is often used as the front end, rear end, upper end, bottom end and phase partitions in the partition system. The insulation performance of these components is crucial to the normal operation and safety performance of the switchgear. With its excellent insulation performance and mechanical strength, GPO-3 board can ensure the stable operation of these components under high voltage and high load environment, thereby improving the reliability and safety of the switchgear.

In addition to the above-mentioned applications, GPO-3 board is also suitable for various switchgear partitions, linings, arc extinguishing hoods, arc extinguishing cylinders, arc extinguishing sheets, arc extinguishing plates, terminal boards, interphase insulation, bottom partitions, contact supports; structural supports for switches and transformers, busbar clamps, etc.

How to distinguish the real GPO-3 board

1. The real GPO-3 board has passed the American Safety Laboratory Certification (UL Certification), so it has an independent UL identification file number. When purchasing this product, you should ask the manufacturer to provide the UL identification file number to distinguish the authenticity.

2. The leakage resistance index of the real GPO-3 board can reach 600V.

3. The density of the real GPO-3 board is between 1.81--1.83 according to international standards. And it does not contain fillers, which determines the reliability and stability of the board.

Simple way to distinguish finished and inferior GPO-3 boards

You can light it with a match.

1. The inferior products produce smoke. GPO-3 board products have very good adhesion. And the material itself is environmentally friendly and will not produce smoke.

2. Toxic gases are produced. Inferior products generally use flame retardants to achieve flame retardant effects, so there are pungent toxic gases when burning. As the flame retardant evaporates, the product performance also decreases. It cannot be used in environments where people are in contact or in hot environments.

3. Combustion stratification. Due to the irregular structure of glass fiber felt, the mechanical tension of GPO-3 board comes from the inside, and internal stratification will not occur during high-temperature carbonization. If there is stratification during combustion, it is a counterfeit product.
