SF6-insulated Ring Main Unit
(SF6-RMU)

SF6 RMUOur SF6-insulated Ring Main Unit for secondary distribution is a type-tested, factory-built, metal-encapsulated switchgear in block/modular construction; for indoor installation.

All the switching devices are fully-insulated with SF6 gas and comprise; load-break switches, earthing switches, metering, bus riser, bus sectionalized panels, SF6 circuit breakers as well as blocks.

Our SF6 Ring Main Units are ready to be integrated with SCADA systems, and other forms of remote controlling whether via compact remote controlling units or for larger switchgear rooms in need of such control.
