110kV Live Tank Outdoor High Voltage Circuit Breaker / Vacuum Circuit Breaker
General
LW36-126 type outdoor circuit breaker is a high performance new
type HV SF6 circuit breaker based on sufficient absorbing and
digesting advanced technology of foreign SF6 circuit breaker, and
according to the requirement of national standard, combining
domestic commercial manufacture level and design.
This product is used in electric system with 50Hz, 110kV system nominal voltage, and which is main electrical equipment controlled and protected by power station and substation. It can be equipped with CT□ type spring operating mechanism and three-phase mechanical linkage. Inside filling SF6 gas having excellent arc extinction and electrical insulation performance. All seals adopt double-circle O type seal ring, which can prevent leakage efficiently.
Features
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 faul.
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.
