Vacuum serves as the ideal dielectric medium for high-voltage relay operations due to its outstanding electrical properties. It offers:
- Exceptional voltage breakdown strength.
- Rapid recovery times of up to 10 kV per millisecond.
- A completely inert environment for switching contacts, ensuring no oxidation or degradation over time.
These characteristics make vacuum relays highly efficient, durable, and reliable for high-performance switching tasks.

Frequently Asked Questions
Looking for a high voltage vacuum relays manufacturer? Why choose vacuum dielectric relays over open-air or gas-filled relays?
Open-air and gas relays suffer from contact oxidation, contact chatter erosion, and slow arc extinction under high voltages. INNOVACERA manufactures ceramic high-voltage vacuum relays that utilize a sealed, inert vacuum dielectric. Providing rapid dielectric recovery rates up to 10 kV/ms and exceptional voltage breakdown strength, our relays guarantee arc-free, zero-oxidation switching and long contact life for RF communication transmitters, HiPot testers, and MRI power supplies.
Need custom high voltage vacuum relays for RF or pulsed systems? Which configuration suits clapper vs diaphragm applications?
INNOVACERA supplies both clapper-type and diaphragm-type vacuum relays with custom coil voltages, contact forms (SPST, SPDT), and mounting configurations. Clapper models excel in handling heavy continuous currents and rugged airborne/marine communication hardware, while compact diaphragm relays provide ultra-fast response times ideal for ESD pulse-forming networks, semiconductor wafer deposition, and radar power modules.
