Solid Sealed Sf6 Vacuum Circuit Breaker,
12kV Sf6 Vacuum Circuit Breaker,
50Hz 12kV Vacuum Circuit Breaker
The EVSY module solid-sealed high-performance vacuum circuit breaker is another technological innovation achievement of Xi'an Senyuan Company on the basis of the successful design and production of the original decentralized spring operating mechanism vacuum circuit breaker. It has independent technical patents.
The working performance of this type of circuit breaker is more stable, and it solves the unreliability of the long-life operation of the spring operating mechanism. The mechanism has fewer parts, simple structure, simple processing and assembly, simple operation and reliable action. The one-time closing and opening curve is smooth, the mechanical properties are optimally matched with the arc extinguishing performance of the arc extinguishing chamber, and the product has strong versatility and wide application range, which can meet the needs of new design projects or special occasions.
The manufacture of EVSPA series vacuum circuit breakers follows the standards and specifications consistent with GB, DL and IEC related publications.
