Siemens Nxairs-40.5kV Gas/air Insulated Medium Voltage Switchgear/switchboard Distributors

Product Detail

SIEMENS NXAirS-40.5 kV Air Insulated Withdrawable Metal-clad medium-voltage Switchgear

1. Characteristics:

All the switch operations can be carried out only under high-voltage compartment door closed.

Reliable mechanical interlock is installed between grounding switch and vacuum circuit breaker handcart.

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

Options: Capacitive electric indicator can be used to detect feeder or bus presence of power.
