G10 material is made of glass fiber cloth and epoxy resin. Glass fiber cloth acts as a reinforcing material, giving G10 material excellent mechanical strength and stability; epoxy resin, as a matrix material, brings good adhesion and electrical insulation performance to G10 material.
Glass fiber is an inorganic non-metallic material with high strength, corrosion resistance, high temperature resistance and other characteristics. In G10 material, glass fiber cloth exists in a multi-layer woven form and forms a solid skeleton structure of the board, which provides solid support for the whole just like the steel frame of a building.
Epoxy resin is a thermosetting resin with excellent adhesion, electrical insulation and chemical stability. When preparing G10 material, epoxy resin is impregnated with glass fiber cloth, which is then dried and hot-pressed to form a dense board structure just like putting on a strong and insulating “coat” for the skeleton.
G10 materials are suitable for electrical insulation because of their excellent electrical insulation performance.
G10 materials have extremely high insulation resistance, which can effectively block the flow of current inside the material, building a solid defense line for the safe operation of electrical equipment.
Its electrical performance remains relatively stable under different temperature and humidity conditions and is not easily affected by the external environment. This allows G10 materials to continue to play a good electrical insulation role in various harsh environments.
Arc discharge is common in high-voltage electrical equipment. G10 material has good arc resistance. Even under the action of arc discharge, it can maintain structural integrity and electrical insulation performance to ensure the normal operation of the equipment.
Dielectric constant and dielectric loss are key indicators for measuring the electrical insulation performance of materials. The low dielectric constant of G10 material means that under the action of the electric field, the material stores less electrical energy and is not prone to polarization; at the same time, its dielectric loss is also low, which can reduce the loss of electrical energy during transmission and improve energy efficiency.
In addition to its excellent electrical insulation performance, G10 materials have many advantages that make them more suitable for electrical insulation applications.
G10 materials can stably maintain electrical insulation performance at higher temperatures and will not lose insulation effect due to temperature increase. They have significant advantages in manufacturing high-temperature electrical equipment.
G10 materials can resist corrosion and erosion from a variety of chemical substances, maintain structural integrity and electrical insulation performance. It is suitable for manufacturing electrical equipment that requires corrosion resistance.
G10 material has high mechanical strength and hardness, can withstand large external forces and is not easy to deform or break. When manufacturing electrical equipment, it can provide reliable structural support and protection for the equipment.
Under different temperature and humidity conditions, the size of G10 material changes very little. When manufacturing precision electrical equipment, it can ensure accurate size and shape to meet high-precision requirements.
