Product Description

Copper Continuously Transposed Conductors (CTCs) are used as winding materials in power distribution, traction, and furnace transformers. The continuous transposition of copper strands enables balanced electromagnetic performance and effective heat dissipation, making copper CTCs suitable for high-efficiency transformer windings where electrical performance, reliability, and long service life are critical.
