 The low-voltage winding of oil-immersed transformer generally adopts the cylindrical structure with copper foil around the shaft except copper wire for small capacity. The high-voltage winding adopts multi-layer cylindrical structure, so that the ampere-turns distribution of the winding is balanced, with small magnetic flux leakage, high mechanical strength and strong short-circuit resistance.
