Technical container e-house
modular solution

Containerized construction
of electrical devices

Containerized construction of electrical devices and automation systems, also known as e-house. Containerized solutions are prefabricated, mobile, portable electrical rooms made each time according to the individual requirements of the customer. Containers are designed for the assembly of various electrical devices such as: transformers, medium and low voltage switchboards, inverters, guaranteed power supply systems, automation systems, etc.

Container-built
transformer stations

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 switchboards

Low-voltage switchboards (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 switchboards

Medium-voltage switchboards are another key element of electrical infrastructure. Their rated voltage is usually a voltage from 1 kV to 36 kV, depending on the classification.
