Distribution Transformers

Designed to be completely sealed from the atmosphere. The internal pressure is set during oil filling using special equipment. When the transformer operates under load, heat causes the insulating oil to expand. This expansion is accommodated by the elastic corrugated tank walls, which expand and contract and also provide cooling. Oil filling takes place in special vacuum chambers to ensure that the transformer is completely filled with oil, with no air inside. The core and winding structure is the same as that of a conservator-type transformer.
