The modular or compact cells with metallic housing isolated in SF6 are specially designed for inside installation in all kinds of underground distribution networks of medium voltage, ringed or not with possibilities of supply from one or various points.
Due to its hermetic construction and that all active elements being within an atmosphere of SF6 gas, its insensitivity to environmental variations, for which they may be used protected at a minimum from rain and direct solar radiation, in any kind of industry or in singular facilities which may be airports, mines, shopping centres, wind generation, hydraulic genration, railway stations, hospitals, etc.
They may also be set up in underground transformation centres with risk of flood. They may work during 24 hours covered by water up to a height of 3 m.
When the place of installation is at a height greater than 1000 m. above sea level, and/or the ambient temperature is not between -10º C and +55º C, we request to be consulted.
The back part of the cells, must keep at a minimum distance of 10 cm. from any wall, with the object of facilitating the exit of gases caused by a quite unusual internal arc.
