Continuously Transposed Conductors（CTC）

    Product introduction

    Transposition conductor is made of a certain number of enameled flat wires arranged in two columns in sequence by special technology, and made of special insulating materials

    Winding wire made of winding material. It is mainly used to manufacture the windings of large oil immersed power transformers, reactors and large capacity dry-type transformers. By using transposed conductor to make transformer, the space utilization ratio of winding is improved, the volume is reduced and the cost is reduced. More importantly, the additional loss of circulation and eddy current caused by leakage magnetic field are reduced. At the same time, it has the advantages of improving the mechanical strength of the winding and saving the winding time.

    The continuous transposed conductor is an important material for the manufacture of transformer winding. The utility model has the advantages of high space utilization rate, low eddy current loss, high mechanical strength and less winding time of the coil.
