Employ a 380V/10kV high-voltage DC power supply system, paired with a 6.6kV backup diesel generator, and a ring main unit (RMU) to ensure dual-circuit 10kV/15kV medium-voltage power supply for critical loads. Government office buildings, schools, hospitals, and other locations utilize prefabricated substations and low-voltage switchgear for intelligent power distribution, meeting the power needs of various scenarios.
