Zw7-40.5 outdoor high-voltage vacuum circuit breaker is a kind of outdoor high-voltage switchgear used in three-phase AC 50hz. 40.5 kilovolts. Using spring operating mechanism or electromagnetic operating mechanism, can be remote control switch, can also be manually controlled energy storage and switch. Used for protection and control of Substation Distribution System, hanging wheel operation and line protection in case of short circuit in rural power network and industrial and mining enterprise distribution system. The circuit breaker is a porcelain columnar structure. The upper KNOB insulator has the vacant arc extinguishing chamber, and the lower KNOB insulator is the post insulator. The circuit breaker is suitable for where frequent operation is allowed. The circuit breaker has the characteristics of reliable sealing, aging resistance, flame resistance, explosion-resistance,long mechanical life,simple installation and convenient debugging.
