Product Description
Pole-mounted Air/Load breaker switch
General
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 capacitive 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.
Application standard: IEC62271-102
