SF6-alternatives Equipment for Transformers

SF6-alternatives Equipment for Transformers

The increasing atmospheric burden of the greenhouse gas sulfur hexafluoride (SF6) have increased the demand for sf6-insulated switchgear, circuit breakers, and transformers. The large bank of sf6 gas sequestered in this electrical equipment provides a substantial source of emissions from maintenance, replacement, and continuous leakage.

  • Alternatives for SF6 | 2020 | Siemens Energy Global

    Hermetically sealed systems with clean air as an insulating gas take up more space than SF 6, but combined with digitalised current and voltage transformers these systems can be built as small as current SF 6 systems. In addition, they are durable and can be used without any problems at the lowest temperatures - down to -50 degrees Celsius.
