40.5KV Vacuum Circuit Breaker Embedded Pole
This 40.5KV vacuum circuit breaker embedded pole features a vacuum arc extinguishing chamber. The component is critical for high-voltage circuit breaker applications, providing reliable interruption of electrical current and arc quenching.
Technical Specifications
Overview
High-Performance Embedded Pole
This 40.5KV vacuum circuit breaker embedded pole utilizes an advanced epoxy solid sealing process (APG) to encapsulate the vacuum arc quenching chamber, outlet seats, and current-carrying components into a single, integrated module. This design significantly reduces the physical volume and part count of the circuit breaker while enhancing insulation, mechanical strength, and thermal aging performance. Engineered for reliability in demanding environments, it offers maintenance-free operation and superior resistance to high and low-temperature shocks, making it ideal for power transmission, chemical, metallurgical, and mining applications.
