Currently, China's medium-voltage distribution networks predominantly operate at 10kV. With rapid economic development, power loads have surged, increasingly exposing the limitations of the existing power supply methods. Due to the outstanding advantages of 24kV high-voltage switchgear in meeting higher load capacity demands, it has quietly gained traction within the industry. Following the State Grid Corporation's "Notice on Promoting the 20kV Voltage Level," the 20kV voltage class has seen a r
