DI-2: Ring Main Unit – GIS

Modular concept combining all medium voltage functions.

Over time SGC – SwitchGear Company has developed the “DI-2”, a modular concept which combines all medium-voltage functions. It allows SGC – SwitchGear Company to provide “made-to-measure” solutions for all your medium-voltage needs.

The DI-2 cubicles and associated switchgear offer a wide range of applications and can be used worldwide in many industries. DI-2 cubicles can be used with distribution and dispersion switchgear, electrical substations and medium-voltage engines, wind generators, cogenera- tion, and much more.

The DI-2 system is a modular concept based on the “building blocks” principle, which means that cubicles are produced in series. As a result, the modular DI-2 concept meets the highest technical standards in a rational, economically sound way. The combination of cubicles is unlimited. Very complex diagrams of distribution and transformer switchgear can be compiled through this extensive spectrum of possibilities.
