A clear commitment of Trench Group and Pfiffner on pure Air as future technology for AIS Instrument transformers.

A joint statement of Pfiffner and Trench to take another milestone for a greener future.

To accomplish our goal to #remove harmful substances and materials from our surrounding environment, Trench Group is collaborating with Pfiffner to take another milestone.
In a joint statement both manufactures express their clear commitment to pure Air as future technology to #remove SF6 insulation from their products. Trench Group and Pfiffner will foster the future development of the Air-based technology for AIS Instrument transformers 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.
