SF6 Pole Mounted Gas Switches
25.8㎸ SF6 Gas Insulated Load Break Switches
25.8㎸ SF6 Gas Insulated Load Break Switches are installed on a 22.9㎸-y overhead. It reignites using SF6 gas which has an excellent heat isolation and arc extinguishing capability and switches load without reignition. With this distribution automation switchgear, the user can operate and check its status using means of communication either on site or remotely.
