Product Description
Continuously transposed conductors CTC Cable is a type of winding wires weaved by certain number of strips of enameled rectangular wires in two ranks according to special technical requirements and wrapped by special insulation material ( insulation paper, rope or tape) .
medium and ultra-high power transformers in electrical equipment
large-scale oil-immersed power transformers
reactors and large-capacity dry type transformers.
CTC Winding Advanatges
By using transposed conductor CTC Winding 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.
