Performance characteristics

a. The low voltage winding of an immersed Transformer generally adopts the cylindrical structure of copper foil winding, except that the copper conductor is used for small capacity; High voltage winding adopts multi-layer cylindrical structure to balance the ampere turn distribution of the winding, with small magnetic leakage, high mechanical strength, and strong short-circuit resistance. 

b. The iron core and winding adopt fastening measures, respectively. The fastening parts, such as the height of the device and the low-voltage lead, are equipped with self-locking locknuts. A structure without a hanging core is adopted, which can withstand the shock of transportation.

c. The coil and iron core are vacuum dried, and the transformer oil is vacuum filtered and injected to minimize the moisture inside the transformer.

d. The oil tank is made of corrugated sheet with respiratory function to compensate for the oil volume change caused by temperature change. As a result, the product has no oil reservoir, significantly reducing the height of the transformer. Therefore, the product has no oil conservator, obviously reducing the height of the transformer.

e. Because the corrugated sheet replaces the oil reservoir, the transformer oil is isolated from the outside world, effectively preventing oxygen and moisture from entering, resulting in decreased insulation performance.

f. According to the above five performance points, it ensures that the oil-immersed transformer does not need to change oil during normal operation, greatly reducing the maintenance cost of the transformer and extending the service life of the transformer.
