mobile sf6 Maintenance Decomposition

Thereby the gas flows automatically via dry and particle filters which effectively adsorb decomposition products and moisture from the gas. During the gas recovery process the SF 6 is stored either in gaseous or in liquid form. Furthermore, the air is evacuated from gas compartments after maintenance works.
