33kv Indoor Voltage Vacuum Breaker

Our 33kv Indoor  Voltage Vacuum Breaker is an indoor device with three-phase AC 50Hz and rated voltage of 33kv,40.5kV, equipped with CT19 spring operating mechanism. 33kv Indoor  Voltage Vacuum Breakers are divided into two types: fixed type and handcart type. The fixed type is used in the XGN17-40.5 box-type fixed high-voltage switchgear; the handcart type is configured on the JYN1-40.5 handcart and used in the JYN-40.5 removable metal-enclosed switchgear or GBC high-voltage switchgear, and can also be configured Used in KYN10-40.5 assembled metal-enclosed switchgear on KYN10-40.5 handcart.
