    Wherever possible do not use SF6 gas: In line with this approach the company has developed air-insulated fixed type switchgear which can be rated at 12 kV, 25 kA, switching up to 2000 A. Wherever possible minimise the use of SF6 gas: Air-insulated fixed type switchgear remains compact up to 12 kV range but at higher voltages it is not possible to achieve compactness using air insulation.
