SFG is an SF6 insulated three-position (close, open, earth on) switch disconnector. All electrically
active parts, including the earthing switch, are in robust epoxy resin housings filled with SF6 (1.45 bar). SFG is a virtually maintenance-free, sealed-for-life (30 years) SF6 unit. Simple and reliable mechanisms in a stainless steel enclosure offer high mechanical endurance. For the SFG, 1000 close/open and 1000 open/earth operations are guaranteed.
mechanism
There are two types of operating mechanisms:
the single spring type and the double spring type. Motor can be added to both types of operating mechanisms.
standards
SFG load break switches meet the following standards:
IEC 60265-1
IEC 60694
IEC 60129
IEC 60420
IEC 60282-1
IEC 62271-102
