Heat Dissipation Structure Ceramic Substrates

Vacuum Interrupter Ceramic Tube

Ceramic Insulator Tubes are used in vacuum interrupters for medium voltage switch gear (approx. 6kV to 80kV).

- Specialized Alumina materials with high insulation
- High reliability ceramic tubes. Mo-Mn metallization with
  nickel plating allows customers to assemble
  hermetically sealed products.
- In-house electrode brazing capability.
- Dedicated production lines, capable of high quality
  and mass production.
