Continuously Transposed Conductors

Tianjin Jing Wei Electric Wire Co., Ltd. [China]

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
