A 35 kV substation is an important part of the power system. Its primary function is to receive, distribute, and step up medium-voltage electrical energy to meet users’ electricity demands. According to operating environments and technical requirements, a 35 kV substation is typically equipped with several key components, including transformers, switching equipment, and protection devices. These components work together to ensure a stable and reliable power supply. In addition, the rated voltage range of a substation generally falls between 31.5 kV and 38.5 kV, with specific tolerances adjusted in accordance with international standards.

To facilitate management and maintenance, detailed operating procedures are usually established. During operation, regular inspections and maintenance of equipment are carried out to ensure proper performance. Below is a brief overview of the basic components of a 35 kV substation and their functions:

Understanding this basic knowledge helps us better appreciate the role and importance of 35 kV substations in ensuring reliable regional power distribution and supply.
