CTC is a bundle of winding wire consisiting of a number of enameled rectangular wires(5-63 strands).

CTC provides a ready-insulated and tightly packed array of conductors for building transformer coils which are suitable for use in the manufacturing of medium and ultra-high power transformers and reactors.

Advantages

  · Shortened winding time for the core of transformer

  · Decreased size and weight of the transformer and reduce the cost

  · Reduced eddy and circulating current losses    

  · Excellent coil performance and simplified winding processing

  · Improved mechanical strength of winding ( Hardened self-bonding CTC)

Production Range

  · Number of strands         5 - 87

  · Width of strand           3.0 - 14.0mm

  · Thickness of strand        1.1 - 3.0mm
