Main areas
of application
Transformer stations have many possible applications in the power generation (mainly RES) and distribution sectors. Elsta offers typical transformer stations with a capacity of up to 2000 kVA in container construction based on a concrete or metal structure. It is possible to make a transformer station with a capacity of up to 10 MVA.
We make transformer stations according to individual needs, which, apart from the implementation of the required technical specification, also include personalization of the station marking in accordance with the visual identification of the Client. We provide an optimal solution dedicated to specialist needs.
Transformer stations manufactured by Elsta are used in distribution energy and RES installations, ensuring safe and stable operation on facilities.

Transformer stations
in container construction
These are solutions that combine a transformer and a switchboard in one container. Thanks to their compact design, they can be installed in places where traditional stations cannot be built.
Low voltage
LV switchgears
Low voltage switchgears (below 1000 V) are key elements of electrical infrastructure. They are used to distribute energy and/or to supply and control separate drives or other electrical devices.
Medium voltage
MV switchgears
Medium voltage switchgears are another key element of electrical infrastructure. Their rated voltage is usually a voltage from 1 kV to 36 kV, depending on the classification.
