CTC with smaller strips

Product catalog summary

Abstract: De Angeli Prodotti is committed to innovation in the Continuous Transposed Cable (CTC) market. Through ongoing research and development, the company has enhanced its production capabilities for small cross-section flat wire used in CTC.

Introduction: The market trend is to reduce the cross-section of single strips in CTC to minimize Eddy losses in windings. De Angeli is addressing this by producing transposed cables with strips as small as 0.8 x 2.5 mm.

Engineering: The new CTC can be constructed with 5 to 55 strips. Internal tests confirm the feasibility of using wrapped paper or netting configurations, with enamels such as PVA/PVF or PEI+PAI for thermal class requirements. Trials also indicate the potential for self-bonding enamel over base varnish, meeting diverse customer needs.

Advantages: Reducing the size of flat wires in CTC offers several benefits: decreased electrical losses in power transformers, reduced winding dimensions due to a better filling factor, and improved flexibility aiding the winding process by reducing the transposition pitch.

Conclusions: De Angeli Prodotti has successfully developed a transposed cable with significantly smaller strip sizes, meeting market demands and enhancing production capabilities. This advancement provides clients with key advantages in manufacturing electrical transformers. The company values its history and ongoing partnerships.
