Greenhouse Gas Management in the Power Sector

SF6 Gas Management Solutions for Power Grids

Sutergy is the authorized agent for the global leading equipment supplier for SF6 Management in power grids Dilo GmbH of Germany.

The Dilo products are applied for SF6 management (Filling, Refilling, Evacuation, Detection, and Monitoring) in medim voltage (MV) and high voltage (HV) switchgear systems and circuit breakers in substations.

SF6 (Sulfur Hexafluoride) Gas Management in West Africa

SF6 is a synthetic, very stable, chemically inert, nonflammable, and nontoxic and in normal conditions it does not react with other substances. It is colorless and odorless, and five-times heavier than air (under normal conditions). It also has good sound insulation properties since the speed of sound in SF6 is one third of that in air, making SF6 a good phonic insulator. It slowly mixes with air by convection and diffusion, and once mixed, does not separate. As it does not react with other gasses, it has a very long life.


SF6 in the Power Sector

SF6 was developed for use as an electrical insulating medium for the power industry. Due to its outstanding insulation characteristics (unique electrical insulation and arc interruption capability), it is used as an insulator and switching gas for gas-insulated and air-insulated switchgear and transformers and to reduce power circuit breaker interruption time. This helps to reduce interruption time thus enhancing power system stability. SF6 gas is used in the commissioning of new high voltage (HV) and medium voltage (MV) switchgear and circuit breakers.

Applications in other sectors

SF6 is also used to some extent in other sectors such as: in medical equipment such as x-ray machines and for electrical insulation in scientific equipment such as electron microscopes and particle accelerators. It was often also used for acoustic insulation in double glazed windows.
