GW4 Isolation Switch

GW4 outdoor MV isolation switch is used for three-phase AC 50Hz outdoor high-voltage electrical equipment, switching of lines under high-voltage no-load conditions, and electrically isolating electrical equipment such as high-voltage busbars, circuit breakers, and live high-voltage equipment for maintenance voltage lines , can also be used to switch small capacitor or inductor current. When the knife is in the normal open circuit position, it can provide insulation distance that meets safety requirements. Widely used in 35-110kV substations.
