Power Supply

It is essential to use only quality and certified equipment and wiring during the design and operation of power systems to prevent future incidents. Power supply means providing consumers with high quality electricity 24 hours a day. The design of the power supply system must be carried out before the repair work. Power supply includes power supplies that increase or decrease substations, transformers that supply distribution networks, various ancillary facilities and structures.

Our engineers (specialists) provide professional services for the efficient use of electricity in all types of buildings.

Our company carries out installation of DC and AC power transmission lines, installation of internal and external (air and cable) lighting networks, installation of earthed devices belonging to all types of earthing circuits.

    We perform the assembly and installation of the following panels:

    • Main Distribution Board (CIS): Receives and distributes electricity in a 380 / 220V - 660 / 380V three-phase AC network and at a frequency of 50Hz in a building or part of a building. Basic Distribution Boards include automatic emergency protection against devices for measuring electricity against any multiple loads and short circuits.
    • Power Distribution Boards (LID): Receives and distributes electricity between the electrical groups of the building, performs power metering on 380 / 220V three-phase AC networks and 50Hz, provides protection of lines from short circuits and overloads. The power distribution board is installed at the entrance of the power cable.
    • Automatic transmission switch (ATS): automatically switches to towing power when the main power supply or power outage is switched off and returns to the main power when it is restored. The ATS provides constant monitoring of the presence of voltage in the circuits of the main and rear power sources, compares the voltage and determines the voltage readings and detects deviations.
    • Distribution boards for multi-storey buildings: receives electricity on the floor and transmits it to the distribution boards of apartments located on the floors of the building.
