Acetal Enamelled Copper Continuously Transposed Conductor
PRODUCT DESCRIPTION
Acetal Enamelled Copper Continuously Transposed Conductor (CTC) consists of multiple individually enamelled rectangular copper strands continuously transposed along the conductor length. The transposition distributes electrical and magnetic stresses among the individual strands, helping reduce eddy-current losses and improve winding efficiency in high-power transformers.
The enamel insulation provides reliable inter-strand electrical separation while maintaining good thermal, mechanical, and dielectric performance. This CTC design is suitable for transformer windings where compact conductor geometry, controlled insulation, and stable electrical performance are required.

Q&A
Q: What is Acetal Enamelled CTC used for?
A: It is primarily used in transformer windings and other high-current electromagnetic applications.
Q: What is the main advantage of CTC?
A: Continuous transposition helps distribute current among individual strands and reduce additional losses caused by circulating and eddy currents.
Q: Can the CTC dimensions be customized?
A: Yes. Strand dimensions, strand count, transposition pitch, insulation thickness, and overall dimensions can be manufactured according to customer requirements.
Q: Can this CTC be used in oil-immersed transformers?
A: Yes. It can be designed for oil-immersed transformer winding applications with insulation systems compatible with transformer oil.
Q: Is the copper conductor individually insulated?
A: Yes. Each rectangular copper strand is enamel insulated before being assembled into the continuously transposed conductor.
