Transposed wire is mainly used in the winding of large oil immersed power transformers,reactors and large capacity dry-type transformers.

Continuously Transposed conductors(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.
