Hermetic Type Distribution
Transformers
Transformers
Long Insulation Life:The transparent insulation oil of the atmosphere does not come into contact with oxygen and insulation deterioration is prevented without oxidation. This extends the insulation life and general service life of the transformer.
Low Maintenance Requirement:No regular maintenance is required other than cleaning under normal conditions and use.
Dimension Advantage:The expansion tank is dimensionally stopped. The transformer, which is the solution to the problem, provides the advantage
Distribution Transformers with Expansion Tanks
Long Insulation Life:Since it is closed to the atmosphere, the insulation oil does not come into contact with oxygen and insulation deterioration caused by oxidation is prevented. This extends the insulation life of the transformer and therefore its service life.
Low Maintenance Requirement:It does not require periodic maintenance other than cleaning under normal conditions and use.
Dimension Advantage:Since there is no expansion tank, the height is reduced in terms of dimensions. This provides an advantage in transformer centers with height problems

It is usually designed with an expansion tank. As a cooling element, radiator groups that can be easily installed and removed are preferred. Depending on the characteristics and importance of the place of use, it is common to equip them with more protection equipment than distribution transformers.
