The free breathing transformers are equipped with a cushion under the cover or a conservator to allow the oil to expand, at the temperature variations. As it is not hermetic, the oil is always in contact with the air. Moisture is kept at bay through the use of dehydrating salts contained in special filters (breather). The tank can be in finned or with radiators. This design applies to all powers, but especially from 4000 kVA and up. For higher powers and to avoid contact between the oil and air, a rubber separator (rubber bag) or a nitrogen cushion is used.
Eco 3+ transformers with amorphous core As of 1 July 2021, all transformer manufacturers will have to strictly comply with the production of transformers classified with the term Tier 2, with the exception of specific applications, as laid down in Regulation no. 548/2014 with Phase 2.

Quay transformers: Shore-to-Ship Respect for the port environment, therefore, reduction of consumption, pollution and noise The regulations in port areas increasingly call for a reduction in the air and noise pollution produced by the ships moored in ports. This requirement is met by using ground power instead of on-board generation during mooring. The shore-to-ship […]
