description: The given work is devoted to the development of technical solutions for a 110/10 kV terminal substation, the choice of 110 kV and 10 kV cables, the choice of equipment for 10 kV switchgear. During in the work, the Schematic diagram of a 110/10 kV substation with a branch transformer at 25 MVA was selected and justified. The methods of neutral grounding in 10 kV system are considered. The permissible long-term current of 110 kV and 10 kV cable lines with cross-linked polyethylene insulation is calculated. Cross-sections of conductive cores and screens are selected. Also the method of grounding screens and its justification are selected. The equipment of 10 kV of local manufacturers is considered. Schematic diagrams have been drawn up for a 10 kV indoor switchgear, a 10 kV distribution point and a 10/0.4 kV transformer substation. A block diagram of a 10 kV distribution system has been compiled. The proposed technical solutions comply with the requirements of reliability and electrical safety of personnel, as well as comply with the modern regulatory framework.
