Air insulated LV, MV switchgears, Generator switchgears, Transient cabinets

We can offer indoor and outdoor switchgears in several classes. We are focused on tailor-made construction and we adapt to your needs. The basic class of switchboards are medium voltage switchgear for distribution - secondary distribution. The switchboards are compact and can be fully customized. Another class is the control cabinets and LV switchboards. As a specialty, we offer so-called transient cabinets in full specture of nominal voltage, mainly for the connection of high voltage cables and, for example, for interconnection of different bus systems from different producers.
The top class of switchboards represents primary distribution cabinets, generator switchboards.

The switchgears are manufactured and tested according to IEC, selected devices also according to GOST, ANSI, IEEE standard. All devices have the option of manual or motor control. They are manufactured in a three-pole, two-pole, one-component and optional multi-pole design. We also offer DC design.

Main terminal boxes of MV generators

The Main Terminal Boxes are used to conduct electrical power to the main current conductors and to create a star point on the opposite side of the generator stators windings. Typically, the cabinets contain measuring current transformers and voltage transformers to protect the generator. They may also include overvoltage protection of generator, optionally with protective capacitors, or a partial discharge measurement system of the generator windings. The cabinets are adapted to the generator design, project by project. It can be one common cabinet for the power output and the star point - MTB & N, or it can be divided spatially into two cabinets MTB part (power output) and N part (star point).
