AC High Voltage Single Pole Switch Disconnector

Switch Disconnector 1.Equipped with self-lock single phase 2.Ensures the high reliability and safety of operation 3.OEM

Product description

AC High Voltage Disconnect Switches are mainly applied in AC10-40.5KV 50HZ power supply system as devices to switch the unloaded high voltage lines with charge and isolate the electical devices such as high voltage bus and breaker etc to repair. These switches are widely used in industries like electric power, railway, mining and oil field.
