Product Description
The GW4-72.5 outdoor disconnecting switch is an AC 50Hz outdoorhigh-voltage electrical equipment. It is used to open and close high-voltage lines under no-load conditions, and to electrically isolate thehigh-voltage lines of the overhauled high- voltage bus, circuit breakersand other electrical equipment. It can be used to open and close smallcapacitor or inductor current.
This series of outdoor disconnecting switches meets the relevantregulations of GB1985 "AC High Voltage Disconnecting Switches andEarthing Switches", IEC60129 " AC Disconnecting Switches and EarthingSwitches" and GB/Tl1022 "Common Technical Requirements for HighVoltage Switchgear and Control Equipment Standards" and otherstandards.
