400KVA Hermetically Sealed Oil-Immersed Power Three Phase Transformer
Feature
1) When the transformer is packaged, the vacuum oiling process is
used to completely remove the moisture in the transformer.
2) After sealing, the transformer oil does not contact with the
air, which effectively prevents the oxygen and water from immersing
the transformer and leading to the deterioration of performance
(aging of materials and oil).
3) The box is the corrugated radiator tank, not only has the
cooling function but also has the 'breathing' function. The
elasticity of the corrugated radiator can compensate the oil volume
change caused by the temperature change.
