:

• Gnee's small distribution transformers up to 315 kVA are typically oil-immersed for pole, pad, or floor mounting.

• Gnee's small distribution transformers up to 315 kVA are suitable for residential overhead distribution loads, as well as light commercial or industrial loads and diverse power applications.

3:

1.The low-voltage windings of oil-immersed transformers generally adopt a cylindrical structure with copper foil around the shaft, except for small-capacity copper wires; the high-voltage windings adopt a multi-layer cylindrical structure to balance the ampere-turn distribution of the winding and prevent magnetic flux leakage Small, high mechanical strength, strong short circuit resistance.

2.The iron core and the winding have adopted fastening measures respectively. The fastening parts such as the height of the active part and the low-voltage lead wire are all equipped with self-locking locknuts. The non-hanging core structure is adopted, which can withstand the vibration of transportation.

3.The coil and iron core are vacuum-dried, and the transformer oil is vacuum-filtered and oil-filled to minimize the moisture inside the transformer.

5.

6.According to the above five points of performance, it is guaranteed that the oil-immersed transformer does not need to change oil during normal operation, which greatly reduces the maintenance cost of the transformer and prolongs the service life of the transformer.
