11kv Outdoor VCB Vacuum Circuit Breaker

SYHF's 12 11kv outdoor VCB Vacuum Circuit Breaker made in China is designed for overhead line protection, rural distribution networks, substations and renewable energy integration. The vacuum interrupter of 12 11kv outdoor VCB Vacuum Circuit Breaker is maintenance-free. Relatively speaking, the vacuum interrupter is the key part to ensure the mechanical life of the vacuum circuit breaker. It adopts vacuum arc extinguishing technology and is installed in a weatherproof and UV-proof housing to provide safe, efficient and maintenance-free operation in harsh outdoor conditions.

12 11kv outdoor VCB Vacuum Circuit Breaker has pole or base design, conforming to IEC 62271-100 and GB/T 1984 standards, suitable for 50Hz or 60Hz systems.

The mechanical life of 12 11kv outdoor VCB Vacuum Circuit Breaker is one of the important factors to measure product quality. There are hundreds of parts inside the vacuum circuit breaker, and the quality of each small part (including auxiliary switches and micro switches) may affect the mechanical characteristics of the entire vacuum circuit breaker. The normal ambient temperature is between -30℃ and 40℃. If the ambient temperature is lower than -30℃, the friction of the circuit breaker drive mechanism will increase, and the circuit breaker will not be able to open and close, resulting in incompatibility.

In order to improve this defect of outdoor vacuum circuit breakers, our company has developed sulfur hexafluoride circuit breakers, which are self-resetting vacuum circuit breakers with sulfur hexafluoride gas filled in important mechanism components. This technology fully integrates the vacuum interrupter and sulfur hexafluoride circuit breaker, ensuring the long service life of the outdoor circuit breaker.
