Core Advantages
- Extremely high dielectric strength in vacuum insulation, ensuring no breakdown and no arcing under high-voltage conditions
- Dielectric recovery rate up to 25 kV/μs, with arc extinguishing completed within half a power frequency cycle
- Low and stable contact resistance, minimal ohmic noise, and lossless transmission in high-voltage applications
- Low excitation power, fast switching speed, and precise, sensitive response in high-voltage systems
- Fully sealed structure, unaffected by air pressure, moisture, or dust, ensuring strong adaptability in harsh high-voltage environments
Application Fields
The high voltage vacuum relay is widely used in high-voltage electrical scenarios such as radio communication equipment, radar systems, fast switching of high-voltage high-power circuits, antenna transmit-receive switching, pulse forming network switching, and high-voltage automatic grounding (leakage protection).
