[0002] Mine high-voltage explosion-proof switches are suitable for mines with explosive and dangerous gases. They control and protect high-voltage lines, and serve as power distribution and direct starting motors. Multiple units can be used in the underground central substation to distribute power to the mining area substation, or multiple units can be connected in parallel to form a high-voltage distribution combination to supply power to the main drainage pump and control these high-voltage electrical equipment.
