          • GW1-12 Outdoor High Voltage Ac Disconnector

          GW1-12 Outdoor High Voltage Ac Disconnector

          GW1-12 series outdoor high-voltage AC isolating switch (hereinafter referred to as “isolation switch”), suitable for installation on outdoor high-voltage power distribution equipment line, for 10kV line to be connected under voltage and no load, and for high voltage to be overhauled Electrical equipment such as busbars and circuit breakers can be electrically isolated from live high-voltage lines, and can also be used to separate small capacitive currents and inductor currents. The isolating switch is a double-column vertical open type with manual or electric mechanism for three-phase linkage. The isolating switch complies with GB 1985-2014 "High Voltage AC Isolation Switch and Grounding Switch", DL/T 486-2010 "High Voltage AC Isolation Switch and Grounding Switch" and other technical standards.
