Main Features and Advantages

1. Excellent Seismic Performance and Stable Operation
The breaker features a low center of gravity and robust structural design, providing excellent seismic resistance. The equipment operates reliably even under severe environmental and climatic conditions.

2. Highly Integrated Design with Reduced Footprint
The compact integrated structure significantly reduces substation space requirements. Its modular design allows flexible installation and facilitates future expansion and maintenance.

3. High Insulation Level and Strong Environmental Adaptability
Optimized electric field distribution and shielding technology improve insulation margins. The breaker is designed to withstand high altitude, heavy pollution environments, and extremely low temperatures, with special low-temperature materials enabling operation in environments as cold as −60 °C.

4. Outstanding Breaking and Current-Carrying Capacity
The circuit breaker provides excellent short-circuit breaking capability (up to 63 kA for 550 kV) with short arcing time. High-performance contact materials ensure strong current-carrying capability (up to 6300 A for 550 kV) and long electrical life, capable of 24 consecutive full-capacity breaking operations at 63 kA.

5. High Mechanical Reliability
Equipped with spring or hydraulic-spring operating mechanisms, the breaker offers a long mechanical service life of up to 10,000 operations, ensuring reliable and stable performance.
