The tank is completely sealed so as to prevent moisture and oxygen from entering into the transformer. When transformer oil comes in contact with oxygen and moisture, the chemical reaction will cause oxidation reaction which leads to cause insulation failure inside the transformer and the transformer becomes less life or will be short circuited.EPA & OSHA Secondary Containment Requirements - The easiest/fastest is to put the day tank into a tank containment tub. This, of course, only works if you are able to lift the tank, and should be done when the tank is empty. If you want to build secondary containment around the day tank, the size of the system will be based upon the volume that the tank Fluid-Immersed Distribution Transformers | Transformers cyprus transformer tank chemical volumeThe distribution transformers tank must dissipate the entire heat loss. In hermetically sealed transformers, the corrugated walls absorb the changes in the insulation liquids volume. Alternatively, the transformer can be designed as an open system or fitted with an oil conservator that compensates for the additional volume.
