InSealing has developed high-voltage insulators designed for vacuum coating systems. These insulators feature a ceramic feedthrough that is securely joined to a ceramic housing with metal assemblies, ensuring a high level of leak tightness with a rate of 4.2e-3 liters per Pascal per second (l Pa/s).
Materials Used:
Insulator: The insulator component is constructed from 96% alumina. Alumina is a ceramic material known for its excellent electrical insulation properties, making it ideal for high-voltage applications.
Flange: The flange portion of the assembly is made from SUS304 stainless steel. Stainless steel is a corrosion-resistant material that provides durability and reliability in vacuum environments.
Contact: Silver is used as the contact material. Silver is an excellent conductor of electricity and is often chosen for its electrical conductivity in high-voltage applications.
Pin: Copper (Cu) is used for the pin component. Copper is another good conductor of electricity and is often used for its electrical properties.
These high-voltage insulators are specifically designed for use in vacuum coating systems. Their construction materials are chosen to provide the necessary electrical insulation, corrosion resistance, and electrical conductivity required for efficient and reliable operation in such systems. Additionally, the leak tightness rate of 4.2e-3 l Pa/s indicates that these insulators effectively maintain the vacuum environment within the coating system, ensuring optimal performance.
