Three Phase Dry Type Transformer
3 Dimension (3D) Wound Cores” are made from three identical single-core frames of trapezoidal silicon steel tape, wound into a compact triangular structure that eliminates air gaps. This innovative design ensures uniform flux flow, reduces total core weight, lowers no-load loss by 20-25%, and decreases excitation current by 50%, significantly minimizing reactive loss and improving the transformer’s power factor (Cos-phi).
