Next important step for our Blue portfolio – Clear commitment of Trench Group and Pfiffner on pure Air as future technology for AIS Instrument transformers substituting SF6!
Both manufactures will focus on the future development of the Air-based technology and collaborate on standardizing aspects which are relevant to customer (e.g., diameter of filling devices). This finally leads to a significant reduction in complexity for transmission operators and their service teams.
Trench has introduced its Blue Instrument transformers® with Clean Air insulation for up to 420 kV and continues the development as part of the REGENERA™ approach.
Please take a look at the joint statement of both companies for more information!
