KYN28A-12 high-voltage switchgear

For the purpose of control, protection and detection, KYN28-12 indoor AC metal armoring movable switch device series, an integrated power distribution unit with 3-12 kV rated voltage, 50Hz three-phase AC, single bus bar and single bus-bar section, are used for power supply in power station, medium and small electric generator, for power distribution in industrial and mining enterprises and public institutions, for power receiving and distribution in substation of power grid, and for initiation of large high-voltage motors. The switchgear can meet the requirements of standards of GB3906, IEC298, etc. Furthermore, it has five-prevention functions, namely, prevention for maloperation of breaker, prevention for pulling the handle on load, prevention for making earth switch in electrification, prevention power transmission as earth switch in earth position, and prevention for reaching electrified compartments. The switchgear can be equipped with VD4 vacuum breaker of ABB as well as VS1 vacuum breaker made by domestic manufacturers, which is truly superior power distribution device.

 

     

 

GCS low-voltage switchgear
    
GCS-type low-voltage withdrawable switchgear is designed and developed by joint design team from two ministries based on the requirements of industrial authorities, vast power consumer and design units, which conforms to national conditions, reaches comparatively high technical performance standard, and has the ability to adapt to development in electricity market and compete with current introduced products. At present, such device is widely used by power consumers.
It is applicable to power distribution system of power stations, petroleum industry, chemical industry, metallurgy industry, spinning industry and tall building.
