Design 1
Проектиране и конструиране за електрически инсталации


Experienced designers having full design capacity work in the “Design and construction” department of CMC-C. The department designs all necessary stages of projects of new sites, extensions, renovations and upgrades of existing electrical installations and systems.


The projects are made by using licensed software products:

  • EPLAN for electrical circuits;
  • SolidWorks for mechanical structures;
  • ETAP- an effective real-time energy management with the ability to monitoring, control, automation, simulation and optimization of the system performance

Our procedure for document control is flexible and relatively easy to adapt to the specific customer requirements.

Erection works at new sites 2

Erection works at new sites

Our technical managers and members of our installation teams have extensive experience in the construction of electrical installations and equipment for new sites.

Our goal is to perform the mounting operations with a minimum number of workers, but highly motivated, trained and disciplined.

We provide our installation teams with modern and good working machinery, facilities, tools, equipment and materials.

The Integrated Management System implemented and maintained by us impresses our clients and partners and without any exception they approve it and accept it without remarks.


Extensions, renovations and upgrades 3

Extensions, renovations and upgrades

We implement extensions, reconstructions and modernizations (retrofit) of industrial and public electrical installations and systems with minimal interruption during their work with high quality and in strict compliance with the legal requirements and those of the client.

We minimize the time for disassembly and assembly works on client’s territory with careful planning and execution of preparation works in the production facilities of CMC-C.

We are paying special attention to the prior approval from client of the technical documentation and the equipment, which is delivered and ready for installation.

Over the past two decades, we have designed and implemented retrofit of hundreds distribution devices for voltage up to 20 kV from different manufacturers – Russian, Bulgarian, German, Finnish, Czech and others.
In parallel with retrofit we are implementing of systems for relay protection with logic discrimination and directional selectivity in MV distribution systems at industrial plants.
