Supply vacuum circuit breaker ZW8-12

ZW8-12 high pressure column vacuum circuit breaker is rated voltage of 12KV new outdoor high voltage switchgear, and is mainly used for urban and rural power distribution system as open, close load current, overload current and short circuit current purposes. ZW8 pressure column vacuum circuit breaker is to replace oil-filled circuit breakers to achieve the ideal of non-oil products. Silicon rubber outer insulation materials, insulation reliability, strong anti-contamination ability. ZW8-12 pressure column vacuum circuit breaker with spring operating mechanism, can be manually operated, electric operation and remote open and close operations. ZW8 vacuum circuit breakers in the side of the installation of disconnectors, outdoor high-voltage vacuum circuit breakers form a high-voltage outdoor isolation switch combinations, increasing the visibility isolated fracture, and reliable interlock operation. According to user requirements, ZW8 pressure column vacuum circuit breaker with the corresponding controller with the composition of the AC high voltage vacuum recloser, automatic segmentation, a self-operating power is to achieve the ideal distribution automation equipment. The use of an external high voltage transformer structure, can be built. ZW8-12 high pressure column vacuum circuit breakers use conditions: (1) the altitude no higher than 1000m (2) ambient temperature limit + 40 ℃, lower limit of -30 ℃ (3) wind pressure does not exceed 700Pa (equivalent to wind speed 34m / s ) (4) non-recurrent severe vibration (5) anti-contamination grade is Ⅲ
