Product Structure

ZW7A-40.5 Series outdoor high voltage vacuum circuit breakers main switchgear of AC50Hz, 40.5KV, which is assembled with spring operating or electromagnetic operating mechanism. It can be operated to switch on/off by remote control, and it is also charged and switched on/off by hand. The design function of breaker complies with the requirements of GB1984-89 and IEC56 “AC high voltage circuit breaker”, it is mainly used in outdoor 35KV distribution system to control and protect, also for normal operating and protecting short circuit of urban,rural network, or industrial enterprises. Its overall structure is supported by porcelain insulator, vacuum interrupter built in upper insulator, downside insulator used for supporting. The breaker applies

frequent operating places with the advantages of good sealing anti-aging, high-voltage withstand, non flame, non explosion long working life, easy installation and maintenance and etc.
