FAQ: What are the key components of a vacuum interrupter?
Q1: What is the role of contacts in a vacuum interrupter?
A1: Contacts conduct electrical current during normal operation and carry the arc when interrupting high voltage currents. Our Vacuum Interrupter uses copper-chromium alloy contacts optimized for durability and minimal erosion.
Q2: How does the vacuum chamber contribute to the interrupter's performance?
A2: The vacuum chamber encloses the contacts in a high vacuum environment, preventing the arc from spreading outside the intended path. Our factory ensures the chamber maintains a vacuum pressure of 1x10^-5 Pa, providing high dielectric strength and reliability.
Q3: Why is the bellows component important in a vacuum interrupter?
A3: Bellows enable smooth movement of the moving contacts while maintaining the vacuum seal. In our Vacuum Interrupter, stainless steel bellows are engineered for long operational life, ensuring consistent performance in electrical switching applications.
