LW9-72.5KV 69KV 66KV high voltage outdoor live tank sf6 circuit breaker
1. Product overview:
LW9 -72.5 porcelain column high voltage AC sulfur hexafluoride circuit breaker is a new product, which adopts
spring operating mechanism and three poles are installed on one frame to realize three-phase mechanical
linkage through transmission mechanism. Electronic controlling can achieve remote and local operation,
product performance is more superior, operating noise is small. It has the ability to break capacitive loadand
inductive load current, It can be used as a special circuit breaker for reactive power compensation.
2. Performance features:
1. Excellent capacitive and inductive current breaking erformance;
2. Longer electrical life;
3. Reliable insulation performance;
4. Longer mechanical life; 5. Safe and reliable operation, small maintenance workload.
