Continuously Transposed Cable(CTC) is a kind of winding wire made of a certain numbers of enameled rectangular wires arranged in two columns in sequence by special technology,and wrapped by special insulating materials.


It is mainly used in the winding of large oil immersed power transformers,reactors and large capacity dry-type transformers.By applying transposed wires to transformers,the space utilization ratio of winding is improved,the volume and the cost is reduced.


Whats more,the additional loss of circulation and eddy current loss 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 etc.


CTC is the important material for transformer winding.It has the advantage of well using of space,low eddy current loss,high mechanical strength and less time of coil winding.
