General Information
ARM Type Vacuum Breakers are one of the main equipment of medium voltage air insulated switchgears. Vacuum breakers have a high ability to extinguish arcs that may occur during opening and closing. Therefore, it has found a wide application area in medium and high voltage systems as arc extinguishing and isolation media. Type tests of Vacuum Breakers manufactured at 36kV rated voltage have been completed in accordance with IEC 62271-100 standard.
