SF6 Vacuum Type 110kV 3150A High Voltage Vacuum Circuit Breaker 50Hz
Features of SF6 Vacuum Type 110kV 3150A High Voltage Vacuum Circuit Breaker 50Hz
A. High performance of breaking, which has the capability to cut off the short-circuit and pull out of the outgoing point, and resolve the close-in fault.
B. The arc-chutes manufactured by the technology of spinning with high quality of airflow and simple structure.
C. Longer electrical service life, the ability of breaking for 20times on full capacity, and long interval for maintaining, free maintenance for 10 years under the normal operation.
D. Operation mechanism in low energy which is simple, reliable and neat.
E. Low rated pressure, not be liquefied under low temperature.
F. Smaller area occupied.
G. Low noise, used in residential areas.
H. Instant on-site installation.
