What Is The Difference Between G10 And G11?

G10 and G11 are both insulating materials, and what is the different between them. Let’s take a look together.

G10 is a composite material made of fiber glass cloth and epoxy resin, originally developed for use in aircraft, and it is capable of withstanding great forces without deformation. This material has insulating and acid-alkali resistance properties, and is not permeable to water vapor or liquids, while being lightweight. These characteristics make G10 insulating material an ideal choice for various fields such as electronics, aerospace, chemical industry, and precision instrument manufacturing.
G11 insulating material is a hard cardboard-like insulating material made of imported electronic-grade alkali-free fiber glass cloth impregnated with imported epoxy resin, and added with corresponding imported flame retardants, adhesives, and other additives and processed by hot pressing. This material has high heat resistance, mechanical performance, and dielectric properties. G11 insulating material is widely used in insulation components in motors, electrical equipment, as well as in aircraft, high-speed trains, transformer insulation boards, etc. It can also be used in humid environments and transformer oil, and is suitable for high-voltage switchgear, high-voltage switches, and other occasions.
What Is The Different Between G10 And G11?
The different of composition:
G10: G10 is a grade of glass epoxy laminate material composed of fiber glass cloth impregnated with epoxy resin. It is known for its high mechanical strength and electrical insulation properties.
G11: G11 is a higher grade of glass epoxy laminate material compared to G10. It is composed of fiber glass cloth impregnated with a higher temperature epoxy resin, making it more heat-resistant than G10.
The different of properties:
G10: G10 has good mechanical strength, electrical insulation properties, and dimensional stability. It is suitable for applications requiring high mechanical performance and electrical insulation.
G11: Compared to the G10, the G11 has a higher heat resistance and is suitable for applications requiring high temperature environments. It also maintains good mechanical strength and electrical insulation properties in high temperature environments.
