The capacity of a 110 kV substation typically ranges from several tens of megawatts to several hundred megawatts, depending on its application scenario and design requirements. In general, small substations have a capacity of about 40–60 MW, while large substations can exceed 200 MW. To meet the electricity demand of different regions, load variations and future growth in power demand are taken into consideration during the design phase.

In terms of basic parameters, a 110 kV substation operates at a voltage level of 110 kilovolts and is capable of supporting large-scale electricity consumption in surrounding areas. In addition, its interconnection system and configured equipment enable efficient transmission and distribution of electrical power, including transformers, switching equipment, and protection devices. These components not only ensure a stable power supply but also enhance the safety and reliability of the power supply system.
