Product Overview
The QCX F-10kV series SF6 gas-insulated metal-enclosed switchgear
(C-GIS) is a switch main unit used in distribution networks and is
now widely used in State Grid, Southern Grid, high-speed railways,
subways, large cities, mines, new energy, and other locations.
All live parts and switches are enclosed within the same stainless
steel welded SF6 insulated sealed gas chamber. The entire
switchgear is unaffected by external environmental conditions,
ensuring operational reliability and personal safety.
The switch units are designed modularly and can be freely combined
according to customer requirements.
Common switch module meanings:
V-----Circuit breaker unit module
PT----Busbar equipment cabinet unit module
FV-----Section circuit breaker cabinet unit module
FG-----Section isolation cabinet unit module
GM----Busbar feeder cabinet unit module
R------Cable connection cabinet unit module
M------Metering cabinet unit module
Product Features
Multi-scheme
There are multiple switch schemes in the design, including integrated and split types, which can be selected according to project requirements.
Maintenance Free
The high-voltage conductor is completely sealed, with incoming and outgoing lines through insulating bushings, maintenance-free for the life cycle.
Miniaturization
Compact structure, reducing the footprint by about half compared to traditional switchgear.
Wide Application
It can be used in high-altitude and humid coastal areas.
