FL(R)N36-12D indoor high voltage vacuum switch

Summary
FL(R)N36-12D Indoor high voltage vacuum switch is a kind of SF6 vacuum switch, fuse combination switch, and can be amounted with cable head. The switch has passed comprehensive testing in accordance with GB3804(3-36kv AC high voltage isolator switch), GB16926(high voltage fuse combination switch), IEC 60265, IEC60420. The switch has three station arc distinguishing chambers, separately for connecting, disconnecting and earthing. It has the advantages of reliable linking lock, high insulation strength of connection, long creepage distance, and also voltage -equalizing cover for wiring connection.
SF6 vacuum switch can be widely applied to three phases AC power system of 10KV, 50HZ.
