description: The research set the following goals: 1. Transformer selection. 2. Choosing of the main electrical connection diagram and auxiliary power supply diagram. 3. Calculation of short-circuit current. 4. Selection of switching devices, measuring current and voltage transformers. 5. Choosing busbars, cables and flexible wires. In this study, a block diagram of the electrical substation was chosen; a communication transformer and auxiliary transformers were selected. The communication transformer converts a voltage of 110 kV into a voltage of 35 kV and 10 kV, and auxiliary transformers convert a voltage of 35 kV into 0.4 kV and 10 kV into 0.4 kV. A feasibility study was made. The main electrical connection diagram and auxiliary power supply diagram were chosen. The short-circuit currents at busbars of different voltages were calculated for five points. The heavy duty current were determined. Switching devices intended for switching an electrical circuit were accepted for installation. Switches and disconnectors were tested by all necessary conditions. The substation equipment was interconnected by conductors. Busbars and insulators for 10 kV switchgear were chosen. Flexible busbars were used to install 35 kV and 110 kV, which were made of steel-aluminum wires. Busbars, insulators and flexible busbars were tested under all conditions. The cable was chosen for RU-0.4 kV Current measuring transformers and voltage measuring transformers were selected. These devices have undergone secondary current testing. As a result of the work, modern, reliable and easy-to-use equipment was chosen.
