  • 220kV Gas Insulated Circuit Breaker(SF6)CB

    Modern SF6 type circuit breakers use compressed gas to interrupt current flow and are common in electrical power substations. Current interruption in a high-voltage circuit-breaker is obtained by separating two contacts in a medium, such as sulfur hexafluoride (SF6), having excellent dielectric and arc-quenching properties.

  • Myth About SF6 Gas In Electrical Equipment

    May 25, 20203. Is SF6 harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse-effect, if it is released into the atmosphere. However in electrical switchgear the SF6 gas is always used in gas-tight compartments, greatly minimising leakage.

  • Breakthroughs in switchgear technology use eco-efficient

    Sep 15, 2017Thus, the search for alternative gases to SF6 for reduced environmental impact continues. A new fluoroketone-based gas mixture ABB has achieved a recent breakthrough with a new alternative to SF6 by commissioning the world’s first high- and medium-voltage pilot gas-insulated switchgear (GIS) bays with a new eco-efficient gas mixture.

  • SF6 Gas Detector for Electrical Utility Companies

    Sulphur hexafluoride (SF6) is an insulation gas used in high voltage equipment. The integrity of numerous electrical substations around the world are being compromised by age, weather, and other factors. As a result, highly potent SF6 emissions are escaping from electrical transmission and distribution equipment at increasing rates.
