Tel (662) 242 5800 (Auto) Fax (662) 242 5818-9, 242 5832-3 Email: SF6 load Break Switch GK SF6 load Break Switch is manufactured according to IEC60265-1 standard with the type tested from KERI Lab. APPLICATION The GK Pole Mounted Remote Controlled SF6 Gas load Break Switch is designed for distribution automation system which typically requires a significant increase in the amount of load - Break operations performed. GK Switches are available for cross arm mounting and is applicable to 24kV and 36kV overhead distribution system. It can be operated electrically (from local control panel or from remote location) and manually.
