Fully Gas Insulated (GIS) Ring Main Unit Type GAE:
The SF6 switchgear panels are type-tested
factory-built, metal encapsulated switchgear assemblies in extensible
construction for indoor installation.
Switching devices built-in are fully insulated with SF6
and comprise: Load-break switches earthing switches, bus riser, bus
sectionalized panels, SF6 circuit breakers and Vacuum circuit breakers.
Our SF6 Ring Main Units are ready to be integrated with supervisory,
control and data acquisition (SCADA) systems and other forms of remote
controlling.
Local work is limited to the connection of external power cables.
Main Features:
