The 25th National \"Safety Production Month\" in 2026: Everyone talks about safety, and everyone knows how to handle emergencies; identifying and addressing potential risks and hazards. -------------------------------------------------- This substation contains 30 10kV medium-voltage cabinets, 2 dry-type transformers, and 24 low-voltage cabinets, and it serves as a key power supply hub for ensuring the stable operation of the entire demineralized water system. The successful power supply to the primary side of this substation lays a solid foundation for subsequent key tasks such as individual testing of equipment, system integration testing, and trial operation of the installations, thereby providing strong support for the timely completion and delivery of the project.
