A transformer is a static electromagnetic device having two or more inductively coupled windings on any magnetic circuit and intended for conversion by means of electromagnetic induction of one or several alternating current systems into one or several other systems without changing the frequency.

Production of HC "Alageum Electric" includes development and production of high-voltage and low-voltage complete devices (both standardized, and according to requirements of the Customer) for systems of power supply, objects of the industry and construction, for automation of various productions, currents to 4000A.

Among the modern high-voltage equipment designed for switching electrical circuits in the energy sector, a special place is given to vacuum circuit breakers. They are widely used in networks from 6 to 35 kV and less in circuits 110 or 220 kV inclusive. In operation, the vacuum circuit breaker is also more simple than small oil and electromagnetic.
