GW4A-40.5W Series
Outdoor High Voltage AC Isolation Switch
GW4A-40.5 series improved outdoor high-voltage AC isolation switch (hereinafter referred to as "isolation switch") is an outdoorhigh-voltage switchgear with a rated frequency of 50Hz. 1t is used for switching 35kV high-voltage lines with votage and withoutload, as well as for electrical isolation of high-voltage busbars, circuit breakers and other electrical equipment under maintenancefrom live high-voltage lines. 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 voltage AC isolation switches and groundingswitches" and DL/T 486-2010 "High voltage AC isolation switches and grounding switches".
The isolation switch complies 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".
