Outdoor Pole Mounted High Voltage Vacuum Load Switch
Introduction - High Voltage Vacuum Load SwitchFZW□-12G/T□, 630 Outdoor Pole Mounted High Voltage Load Switch adopts SF6 gas as the arc chamber and insulation media. It is mainly used in the AC 50 Hz 12 kV rated voltage transmission circuit for opening and closing the load current as well as the partition transformer, unload current and capacitor group current. It also can be used as partition switch. This load switch is configured with spring operation mechanism which can operate manually or electrically. It is applied to frequently used places.
Working & Environmental Conditions - High Voltage Vacuum Load Switch
