SIEMENS NXAirS-12 kV Air Insulation Withdrawable Metal-clad medium-voltage Switchgear

1. Characteristics

· Mechanical dynamic position indicator

·The closing/opening status of disconnecting switch and grounding switch can be indicated respectively on mechanical dynamic position indicator.

·Operating handle socket and control elements are obviously set adjacent to closing/opening indicator of controlled switches.

· All the switch operations can be carried out when high-voltage compartment door closed.

· All the parts and components installation heights meet the requirements of human engineering.

· Options: Capacitive electric indicator can be used to detect feeder or power of busbar.
