What are the characteristics of GPO-3 insulation board?

GPO-3 is essentially the same material as UPGM-203. It is made of alkali-free glass fiber felt board impregnated with unsaturated fatty alkyd resin paste. During the production process, it is added with a certain amount of preservatives and finally pressed. It is a kind of high-quality forced plate insulation material. This kind of insulation material can be used in many products, such as disconnectors, high-voltage switchgear, baffles and other material compositions.

The characteristics and advantages of GPO-3 laminated board are widely used in disconnectors, high-voltage switchgear, baffles and other materials, which is closely related to its own characteristics and materials. This kind of insulation board is essentially an unsaturated polyester glass fiber felt board material. Its production process is to impregnate the alkali-free glass fiber felt board with unsaturated fatty alkyd resin paste, and add a certain amount of preservatives in this production process. Finally, it is pressed at high temperature to form a forced plate insulation material.

GPO-3 laminate has very good dielectric strength. Because it is a conductor and insulator with stable properties, it has strong corrosion resistance and can play a good insulation role in complex environments such as high temperature and humidity. It is more widely used in the electrical industry. Secondly, it has a very good flame retardant performance. It will not ignite in the event of a fire and will protect the equipment from being burned. Its physical properties are also very strong and will not be damaged under external high pressure. It is a good protector of electrical equipment or industrial equipment. In addition, it also has good temperature resistance. When the external temperature continues to rise, it still maintains a certain reliability.
