Package transformer substations
We build the substation for your site: power transformer, HV and LV switchgear and enclosure. The partner factory makes transformers, HV and LV cabinets and metal enclosures itself — everything is assembled and tested in one workshop.
- Design
- box-type, American-type, containerised
- Transformer
- oil-immersed or dry-type
- Rating ZGS
- 75–3 750 kVA
- Supply scheme
- radial or ring
- Tests
- factory acceptance tests
Substation types
Box-type substation (European type)
Transformer, HV switchgear compartment and LV switchgear compartment in one metal enclosure. Installed on a foundation, serviced through the compartment doors.
American-type package substation ZGS
Transformer and HV section in one tank, cable entries via separable insulated connectors. Compact, for ring and radial networks.
Substations for solar and wind plants
Step-up substations for solar and wind power plants: transformer and switchgear on a common frame.
Containerised (prefabricated) substations
All equipment is installed and tested at the factory inside the container — only the cables remain to be connected on site.
American-type package substation ZGS
Losses per the factory catalogue. HV and LV voltage, vector group (Dyn11, Yyn0) and impedance voltage 4–6 % — to suit your network.

Switchgear
We equip the substation with cabinets from the same factory — or supply them separately.
- Switchgear KYN28A-12 — Switchgear cabinets 10 kV with withdrawable circuit breakers
- Switchgear KYN61-40.5 — Switchgear cabinets 35 kV
- RMU HXGN-12 — Ring main units 10 kV
- DFW-12 — High-voltage cable cabinets
- GGD, MNS, GCK/GCS — Low-voltage distribution boards 0.4 kV
- SLVA — Reactive power compensation units 0.4 kV
How we work
- We receive the questionnaire or single-line diagram
- We select the transformer and cabinets and agree the layout
- We send photos and video of assembly and tests at the factory
- We deliver to site and hand over the documentation in Russian
