The free-breathing transformers are equipped with a cushion under the cover or a conservator to allow the oil to expand at 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 filled or with radiators.
This design applies to all powers, but especially those of 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.
