    GN30-12

    GN30-12 indoor high voltage  disconnect switch.. is the rotation touch knife type switch disconnector , main structure lay at top and down platforms , fixed the two sets of insulator contacts , open and close knife switch by rotate the touch knife.

     

    Our GN30-12 indoor high voltage disconnect switchis an indoor electric apparatus of rated voltage 12kV, three-phase AC50/60Hz. It is used to make the break and transfer current for HV electric apparatus under situations with voltage and no-load. The switch applies rotary moving contact which is mounted on the switchgear easily. It adopts wall through the installation as well.
