Product Overview
GW5-40.5 outdoor isolating switch is an AC 50Hz outdoor high- voltage electrical equipment. It is used to open and close high- voltage lines under no-load conditions, and to electrically isolate the high-voltage lines of the overhauled high-voltage bus, circuit breakers and other electrical equipment. It can be used to open and close small capacitor or inductor current.
This series of outdoor isolating switches meets the relevant regulations of GB1985 “AC High Voltage Isolating Switches and Earthing Switches”, IEC60129 “AC Isolating Switches and Earthing Switches” and GB/T11022 “Common Technical Requirements for High Voltage Switchgear and Control Equipment Standards” and other standards
