GW4-40.5 OUTDOOR HIGH VOLTAGE DISCONNECTING SWITCH
Product Overview
GW4-40.5 outdoor disconnecting switch is an AC 50Hz outdoor high- voltage electrical equipment. It is used to open and close high-voltage lines under no-load conditions, as well as to electrically isolate the high- voltage lines of the overhauled high-voltage bus, circuit breaker and other electrical equipment. It can be used to open and close small capacitor or inductor current.
This series of outdoor disconnecting switches meets the relevant regulations of GB1985 “AC High Voltage Disconnecting Switches and Earthing Switches”, IEC60129 “AC Disconnecting Switches and Earthing Switches” and GB/T11022 “Common Technical Requirements for High Voltage Switchgear and Control Equipment Standards” and other standards
