We offer our customers high-quality components, best quality control and warranty on our products.

We perform assembling and installation of the following types of panels:

  • • Main distribution board (MDB): receives and distributes electrical power throughout the building or a separate part of it in a three-phase alternating current network of 380/220V - 660/380V and a frequency of 50 Hz. The MDB contains automatic emergency protection against any overloads and short circuits as well as devices for electrical power metering;
  • • Lead-in distributor (LID): receives and distributes electrical power among electric groups in the building, performs counting of power in three-phase AC networks of 380/220 V and a frequency of 50 Hz, protects lines from short circuits and overloads. The LID is installed at the input of the power cable;
  • • Automatic transfer switch (ATS): automatically switches to backup power during disconnection of the main power source or power outage and returns to main power when it is restored. ATS provides constant monitoring of the presence of voltage in the circuits of the main and backup power sources, compares current ​​and set values of voltage and detects deviations from the norm;
  • • Distribution board for multi-storey buildings: receives electric power on the storey and distributes it among distribution boards of apartments located on this storey of the building;
  • • Distribution boards for apartments of multi-storey buildings: count and distribute electric power inside apartments, small cottages or houses;
  • • Lighting control panel: receives and distributes AC power at a frequency of 50 Hz as well as switches on/off infrequently the group circuit lines, breaks off the electric chains, ensures overload protection and faults the three-phase AC networks;
  • • Uninterruptible power supply (UPS): ensures uninterrupted power supply of equipment and devices of paramount importance such as computers, control and monitoring systems, medical equipment, alarm and other systems;
  • • Auxiliary power unit (APU): provides AC power supply (0.4 kV) for equipment of auxiliary substations and power stations (lighting, heating, etc.);
  • • Control cabinets: ensure control and automation of various engineering equipment, technological processes, emergency alarm, information transfer to the control center, execution of operator's commands, distribution of electric power and protection of consumers and equipment and many other operations.
