1250kva Three Phase Oil Immersed Distribution Transformer 11KV
Fertures
1) The high-voltage winding adopts a multi-layer cylindrical structure, so that the ampere-turn distribution of the winding is balanced, the magnetic flux leakage is small, the mechanical strength is high, and the short-circuit resistance is strong.
2) The iron core and the winding are respectively fastened. The fastening parts such as the height of the device and the low-voltage lead wire are equipped with self-locking locknuts, and the non-suspending structure is adopted, which can withstand the shock 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.
