    Indoor high voltage electrical components

    Zn23-40.5 series indoor high voltage vacuum circuit breaker

    Zn23-40.5 series indoor high-voltage vacuum circuit breaker is an indoor device with three-phase ac 50Hz and rated voltage of 40.5kV, equipped with CT19 spring operating mechanism. The products are divided into two types: stationary and mobile. The stationary type is used in the configuration of xgn17-40.5 box high voltage switchgear; Hand car type configuration is used in jyn1-40.5 hand car in jyn-40.5 movable metal closed switch cabinet or GBC high pressure switch cabinet, or can be configured in kyn10-40.5 hand car in kyn10-40.5 assembled metal closed switch cabinet.
    This series of products have high technical parameters, strong breaking ability, reliable movement, stable performance, long life, simple maintenance, and no explosion risk and pollution, and are used for the control of industrial and mining enterprises, power plants and substations, and can be used for frequent operating places, or for special occasions such as capacitor Banks.
