++++General
FGW1 Series is an outdoor high-voltage air insulating disconnecting switch, that used in MV
power networks for switching them on and off. And that provide support for a reliable and safe
operation of networks. They are suitable for preserves with strict ecological regulations.
The FGW1 disconnectors are used to achieve a clearly visible disconnection of parts of
power distribution networks, passing through a process of repairs, revisions and other works
which necessitate to have the line in a non-live state.
