İSTEK Engineering manufactures, assembles and installs power and control panels of any complexity (up to 4000A) and uses components for assembling panels from world manufacturers. Panel assembly is carried out by highly qualified personnel in accordance with the project specification, international technical standards and local codes and requirements. We offer our customers high quality components, we control and guarantee the best quality of our products.

We assemble and install the following panels:

• Main switchboard (MSB): Receives and distributes electricity in a building or part of a building in a three-phase AC network with a voltage of 380/220V - 660/380V and a frequency of 50Hz. Basic switchboards include automatic emergency protection against any multiple loads and short circuit power measurement devices.
• Electricity Distribution Boards (SHRP): Receives and distributes electricity between the electrical groups of the building, keeps records of power in three-phase alternating current networks 380/220V and above 50Hz, provides line protection against short circuits and overloads. The switchboard is installed at the input of the power cable.
• Automatic Transmission Switch (ATS): Automatically switches to traction power when main power is cut or power is lost, and returns to main power when restored. ATS provides continuous monitoring of the presence of voltage in the main and rear power supply circuits, compares voltages and determines voltage readings and detects anomalies.
• Distribution boards for multi-storey buildings: It receives electricity on the floor and transmits it to the distribution boards of apartments on the floors of the building.
• Shields for cutting floors in multi-storey buildings: metering and distribution of electricity in apartments, cottages or houses.
• Lighting control panel: accepts and distributes AC power with a frequency of 50 Hz, and also turns on / off group circuits, breaks electrical circuits, protects AC networks from overloads and malfunctions.
• Uninterruptible Power Supply (UPS): Provides uninterrupted power to critical equipment and facilities such as computers, control and monitoring systems, medical equipment, alarms, and other systems.
• Auxiliary Power Plant (APU): Provides AC power (0.4kV) for power plant equipment (lighting, heating, etc.) and auxiliary substations.
• control panels: engineering equipment, technological processes, alarms, data transmission to the control center, execution of operator orders, distribution and consumption of electricity, protection and automation of equipment and many other operations.
