The invention discloses a dry transformer which comprises an upper clamping plate, a lower clamping plate and a transformer body mounted between the upper clamping plate and the lower clamping plate.The transformer body comprises an iron core, an upper low-voltage coil, an upper high-voltage coil, a lower low-voltage coil and a lower high-voltage coil, the upper low-voltage coil and the upper high-voltage coil sequentially sleeve the upper end of the iron core, the lower low-voltage coil and the lower high-voltage coil sequentially sleeve the lower end of the iron core, an inner gasket is arranged between the upper low-voltage coil and the lower low-voltage coil, an outer gasket is arranged between the upper high-voltage coil and the upper high-voltage coil, an upper folding screen is arranged between the upper low-voltage coil and the upper high-voltage coil, a lower folding screen is arranged between the lower low-voltage coil and the lower high-voltage coil, and a gap is reserved between the upper folding screen and the lower folding screen. By arranging the upper folding screen and the lower folding screen and reserving the gap therebetween, insulativity can be improved, and discharging effect among high-and-low-voltage coils is prevented effectively; axial interval is reduced, so that length of the iron core is reduced, size of the transformer is reduced, and making costcan be saved.
