  • ABB High Voltage Service Gas Management Solutions

    ABB offers on-site and off-site gas handling services to reclaim, recycle, and purify the SF 6. The reclamation process involves re-moval of the gas, filtration, and restoration. This is often performed in conjuction with maintenance. Recycling gas involves removal of the gas, with an option for ABB to purchase or provide a credit for used SF 6 gas.

    The only significant drawback has been the use of SF6 gas, which requires very careful handling to avoid environmental issues. That drawback has been greatly reduced with AirPlus gas, now available in ABB GIS. This video from ABB Customer World explains the key benefits of this environmental breakthrough.

  • SF6 Decomposition Reclamation

    SF6 Decomposition Reclamation. Abstract: The increasing application of SF6 as an insulating gas has led to many studies on SF6 decomposition in gas-insulated equipment. In the presence-of an electric arc, spark or corona, SF6 decomposes to a wide variety of chemically active products which possess completely different properties from SF6.

    Sep 30, 2020“Equally problematic is that SF6 will, under normal operating conditions, produce hazardous decomposition products when exposed to electrical discharges. The most dangerous of these fluoride by-products is disulfer decafluoride, a colourless gas or liquid that is highly toxic, but produces few immediate physical side effects, making it difficult to detect exposure.
