GFG 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). GFG is a virtually maintenance-free, sealedfor-life (30 years) SF6 unit. Simple and reliable mechanisms in a stainless steel enclosure offer high mechanical endurance. For the GFG, 1000 close/open and 1000 open/earth operations are guaranteed.The switch disconnector is available with a singlespring mechanism for independent open/close operation, or alternatively with a double-spring mechanism with a tripping facility (fuse, coil or bush button).The switches with both types of mechanism can easily be motorized and used as part of remotely controlled system.For easy installation, the GFG is available with a corrosion-resistant sheet steel (AluZink) frame. The switch with a frame is called a “Top Unit”.
