First steps and dynamic development

Our history began in 1992 with foundation of a company called RPA "Eltis Co. Ltd".

Development of rectifiers for city electric transport and metro, and further numerous studies in this field gave the basis for the Company's becoming the largest manufacturer of electrical equipment in Ukraine.

Talented team of our engineers developed a unified series of converters for city electric transport and metro traction substations. They also developed a series of rectifiers based on modern components. These rectifiers successfully passed all qualification and type tests, including thermal tests and short-circuit tests.

From the beginning of its activity the Company goes hand in hand with new technologies and creates innovations — it was during this period that we developed and implemented unique for that time microprocessor controllers for rectifiers control and diagnostics system at city electric transport substations.

Contemporary history

In 1996 the Company was named CJSC "Pluton", and from this moment our contemporary history starts.

The Company takes part in numerous successful startups of trolleybus lines in Ukraine, Republic of Belarus, Russian Federation and Republic of Turkmenistan.

Against the clock

Holding firmly to innovative approach in research and production, and having passed several stages of development, the Company achieved implementation of a new and, subsequently, very successful idea — production of low-maintenance automated complex without participation of people in control operations, switching of traction substation equipment. This concept was implemented in DC switchgears 600 and 825 V. Highly reliable components and modern control systems were applied there.

In our opinion, the disconnectors that we have used in the new generation switchgears are able to make a revolution in DC distribution technology, and these innovative solutions are successfully used in production of PLUTON's products at the moment.

New ideas

Reaching the new peaks and movement only forward — 1999 was marked by development of new, promising directions in electrical engineering, such as AC drive and APCS (Automated Process Control System). As a result, the Company signs numerous contracts and implements major projects that have become our pride.

New opportunities

Not only our professionalism has grown over the previous years. The Company has gained more directions, projects, ideas and talented specialists — it's time to move to a new level.

In 2000 PLUTON acquired production facilities of "Hartron-Elektroavtomatika" enterprise, and a new period in the history of the Company has begun. 17000 sq.m. extension of administrative and production facilities allowed strengthening production sector: assembly areas, welding production, printed circuit cards assembly area, packaging area, type tests laboratory equipped with modern testing equipment.

The company successfully expands application area of its equipment and geography of supplies: now PLUTON equipment is supplied not only to transport enterprises, but also to industrial, metallurgical enterprises and energy facilities in Ukraine, Russian Federation, Republic of Lithuania and Republic of Moldova.

Individual approach to each project and high level of professionalism allows the Company to confidently undertake projects of different complexity and successfully implement them.

On the way to new progress

Constant researches and sustainable development of the Company, accumulated professional experience brings new progress to PLUTON: development of a new rectifiers series with microprocessor-based control and diagnostics system.

PLUTON actively works on various solutions for metro: development of complete set of 825 V DC distribution and tunnel equipment, as well as new control system for metro main ventilation fans ShSAUV. Continuously modernized ShSAUV system is subsequently supplied to Minsk, Kiev, Kharkov and Baku metro.
