33kV Air Break Switch
The air break switches install in outdoor and mainly use for switching and isolation. The air break switch is mostly installed in the distribution network as a switching point. It interrupts the small excitation current of a transmission line or the capacitance charging current. The maximum voltage for the switches is up to 35kV. The air-break switches are classified into two types. They are Single-Pole Air-Break Switch and the Gang Operated Air-Break Switch The (H)GW series outdoor Air/Load breaker switch is a three-phase AC 50Hz /60Hz outdoor medium-voltage switchgear, which can open and close the power line and can see the obvious disconnect distance. Application voltage levels include 12kV, 24kV and 36kV.
