Overview
The GW9-12 series outdoor high-voltage AC isolation switch is a single pole structure and high-voltage switchgear used for opening and closing circuits in outdoor 12kV line networks with voltage and no load. Equipped with fixed hooks and self-locking devices, using insulated hook rods for flexible and reliable operation. Among them, the anti fouling outdoor high-voltage isolation switch can meet the requirements of users in severely polluted areas and effectively solve the pollution problems that occur during the operation of the isolation switch.
