Transformer stations for distribution networks on levels 5 to 7

From 2019, we will be offering you complete high-quality building solutions from our supplier, Betonbau from Germany, for internal arc-tested, compact factory-built stations in concrete in accordance with SN EN 62271-202 - in addition to our own product types - at the Villmergen plant.

For all other types of stations, we can provide you with tailor-made or according to your specifications
SN EN 61936-1 built solutions: indoor systems, free-standing building solutions in concrete, underground or underfloor stations, robust standard container solutions.

SF6-free medium voltage systems up to 24 kV

The SF6-free metal-enclosed compact switchgear according to SN EN 62271-200 «ECOS-C» (2 to 7 fields, 630A, up to 24kV) are further developed and manufactured by the Driescher company in Germany. A standardized configuration (630 A) of the individual fields allows maximum flexibility over the entire service life.

Low-voltage SGK in control cabinets

We are the original manufacturer of switchgear combinations according to SN EN 61439-5 (PENDA-I) in control cabinets and for solutions from 630 to 2000 A for use in public energy distributions.

Cable distribution cabins

We are the original manufacturer of switchgear combinations according to SN EN 61439-5 (PENDA-O) for solutions up to 1000 A in our own, steel-reinforced concrete housings.

Continuity in the availability of the same design is important to us. As a manufacturer, we can also supply you with simpler plastic cabins, equipped according to your needs.
