CTC conductor transformers use special conductor arrangement and replacement technology to reduce the effects of current imbalance and magnetic field asymmetry, and to improve the operating efficiency and stability of the power system.


(1) Conductor arrangement: the conductor arrangement of CTC transformer adopts cross replacement, i.e. replacing neighboring conductors so that the conductors of each phase are evenly distributed in the transformer. This arrangement reduces asymmetrical current distribution in the conductors and minimizes the effects of current imbalance and magnetic field asymmetry.

(2) Coil structure: The coil structure of CTC conductor transformers generally adopts multi-layer windings and realizes cross-arrangement by replacing the conductors in each layer of the windings. The conductors of each phase are intertwined through a complex replacement, which results in a more uniform current distribution in the winding.

(3) Suppression of current imbalance: through the cross-arrangement of conductors in the CTC conductor transformer, the current is distributed more evenly in the winding, thus effectively suppressing current imbalance. This helps to reduce the load imbalance of the power system, improve energy utilization and reduce energy waste.

(4) Elimination of magnetic field asymmetry: the special conductor arrangement of the CTC transformer can also reduce the asymmetry of magnetic field distribution. The cross substitution of conductors can make the magnetic field distribution of each phase uniform, reduce the asymmetric influence of magnetic field, and reduce the electromagnetic interference and loss in the electrical system.

(5) Advantages and applications: the main advantages of CTC conductor transformers are better power utilization, reduction of current imbalance and magnetic field asymmetry, and optimization of power system operation stability. Commonly used in demanding power systems, such as industrial power grids, power plants, substations and so on. It is especially suitable for large-capacity transformers and long-distance transmission lines.

Compared with traditional transformers, CTC conductor transformers may have higher manufacturing costs and technical requirements due to the complexity of conductor layout and manufacturing process. Therefore, system requirements, economy, feasibility and other factors should be considered comprehensively in practical application.
