35KV high voltage vacuum circuit breaker is one kind of outdoor high voltage switch equipment which is suitable for 40.5kv, three phase 50Hz (60Hz). It is can be used as switch-on or switch-off load current, overload current and short circuit current. It is widely used for rural power system. The main structure is porcelain support pole type, vacuum arc distinguished chamber is installed in the upper porcelain insulator and three phase is installed in the same box. Arc distinguished chamber is connected with operation mechanism through connecting lever and insulation lever.
35kv high voltage vacuum breaker is optional by user using support frame to meet distance of electrified body to ground, also can choose concrete frame instead of metal frame.
Standard support frame height for 35kv high voltage vacuum breaker: middle position is 1300mm and highland position is 1200mm
