3D Core is a structure with 3 identical single frame continuously wound by several trapezoid tape; three pillars of the core shape a equilateral triangle and the 3 phases are symmetrical. 3-phase magnetic circuits of the core are completely balanced; the magnetization direction is identical with the direction of rolling of silicon steel, magnetic flux distribution is even with neither lap nor seam; there is neither obvious high resistance area nor distortion of density of magnetic flux at the seams.

Advantages of 3D Transformers over conventional stack core / wound core type transformers:
3D Core transformer is an energy-saving transformer with better structure and performance. It has the following outstanding benefits:
a c Reduced Material- Less Weight
a c Reduced Energy Loss-Energy Saver
a c 3-Phase Equilibrium, Equal Load
a c Low No-load Current
a c Low Noise, Installation anywhere
a c Overload Capacity-Natural Cooling
a c Strong Emergent Short-circuit Protection
a c Low Strength of Electromagnetic Field
a c Low Current Harmonic Spectrum
