SF6-alternatives leakage for Transformers

SF6-alternative gases Transformers factory. Sulfur hexafluoride (SF6) shows excellent insulation performance as an insulating gas. It is suitable for various climate conditions due to its low boiling point (−64 &C). Therefore, it has been widely used in power grid equipment. Alternative Environmentally Friendly Insulating Gases for SF6.
