The GW1 outdoor high-voltage disconnect switch is suitable for power supply systems with a rated frequency of 50Hz or 60Hz and rated voltages of 12kV/24kV. It is used for switching high-voltage lines under no-load conditions and for electrically isolating high-voltage electrical equipment, such as high-voltage busbars and circuit breakers under maintenance, from live high-voltage lines. Additionally, it is used to change the system's operating mode, switching busbar transfer currents and small currents within specified ranges for voltage transformers, lightning arresters, and similar equipment.
