GW4A-12 Series

Outdoor High Voltage AC Isolation Switch

GW4A-12 series improved outdoor high-voltage AC isolation switch (hereinafter referred to as "isolaion switch") is an outdoorhigh-voltage switchgear with a rated frequency of 50Hz. It is used for switching 10kV high-voltage lines with votage and withoutload, as well as for electrical isolation of high-voltage busbars, circuit breakers and other electrical equipment under maintenance from live high-voltage ines. lt can also be used for breaking and closing very small capacitive and inductive currents.
 
The isolation switch complies with technical standards such as GB/T 1985-2014 "High votage AC isolation switches and groundingswitches" and DL/T 486-2010 "High voltage AC isolation switches and grounding switches"
