Features


Low loss: Because the three-dimensional core dry type transformer has the characteristics of small joint magnetic resistance, the magnetic circuit of the corner is consistent with the magnetic direction of the silicon steel sheet, the winding tight filling coefficient is high, and the iron core is light. Compared with the traditional stacked core dry transformer, the no-load loss Po can be reduced by 18%-28%. The no-load current Io drops by 50%-60%. The energy saving effect is remarkable and the operation is economical.

Low noise: The noise level of the three-dimensional core dry-type transformer is 6-10 dB lower than that of the stacked iron core transformer.

Low PD: The product is insulated with non-toxic and flame-retardant NOMEX paper. The NOMEX paper is a Class C insulation material that can withstand high temperatures of 220 degrees Celsius for a long time. The coils are all vacuum immersed and the layers are completely saturated and free of air bubbles. The partial discharge of the product is controlled below 5PC.

High mechanical strength: The three-dimensional coil core adopts a circular core cross section, and the short-circuit resistance is better than the long round section. The coil after vacuum varnishing has high strength and adopts special fastening method. The product can withstand sudden short-circuit electric power without damage.
