GW1-12 Series
Outdoor High Voltage AC Isolation Switch
The GW1-12 series outdoor high-votage AC isolation switch (hereinafter referred to as "isolation switch") is suitable for installatioron outdoor high-voltage distribution eauipment lines, providing 10kV lines with voltage and no load for switching, and for electricaisolation of high-voltage busbars, circuit breakers, and other electrical equipment under maintenance from live high-voltage lines. lt can also be used to separate and close very small capacitive and inductive currents.
The isolation switch is a double column vertical opening type, equipped with manual or electric mechanisms, and can achievethree-phase linkage.
lsolation and isolation comply with technical standards such as GB/T 1985-2014 "High voltage AC isolation switches and groundingswitches" and DL/T 486-2010 "High voltage AC isolation switches and grounding switches".
