(H)GW9A-12 Outdoor High-Voltage AC Disconnector

(H) GW9A-12 outdoor high-voltage single-pole disconnector (hereinafter referred to as disconnector) is a three-phase AC 50Hz high-voltage power distribution device with the rated voltage 12kV, suitable for 10kV power supply system for cutting off and closing the high-voltage line with voltage under nonload and for electrical isolation of the electrical devices under repair such as high-voltage bus and circuit breaker from the live high voltage line. It is also used to turn on/off a very small capacitive current and inductive current.
