CTC Introduction:
Continuously Transposed Conductors (CTC) is one of Gold Cup Winding Wires key products, it is an important material for transformer winding. It has the advantage of high utilization of space, low eddy current loss, high mechanical strength, less time to wind etc.. It is mainly used in manufacturing the winding of power transformers, reactors and traction transformers.
CTC  Features:
Gold Cup Winding Wires is specialized in manufacturing copper and aluminum CTC, and its CTC has following advantages:
Precision product overall dimension
Short pitch transposition
Moderate wrapping tightness
The continuous length without joint is more than 4000m.
