Air insulated medium voltage switchgear 12 to 36 kV - Grany
Full range of air insulated switchgear modular distribution units of up to 36 kV in a metal enclosure, equipped with a breaker, switcher, disconnecter and fuses.
Main characteristics
Grany modular medium voltage distribution units with insulated connections in air and cut-off in SF6 gas, with a metal enclosure, cover all medium voltage (MV) networks ranging from 12 to 36 kV. The units can be motorised and may optionally be equipped for the remote control of facilities, even at a future time.
Main characteristics, which can easily be adapted to your specific needs:
- Rated voltage: 12 to 36 kV
- Rotated 3-position switch-disconnecter cut-off in the SF6 gas
- Many single-line options available
- Tumbler mechanism: switch incoming unit and related fuse switch
- Hanging mechanism: combined fuse and switch units
- Manual or motorised controls
- Disconnectable switch using vacuum circuit breaker technology
- MV metering using many measurement possibilities (TC and TT)
- Nominal current of 400 and 630 A
- Short circuit current of up to 20 kA
- Internal arc resistance
