Copper Tape

Copper tape is cut from cold-rolled copper and wound onto rings. The copper is annealed and degreased.


Cu ≥ 99.90 % with a high or even very high electrical conductivity.


The application of copper tapes provides advantages in distribution transformers and chokes for pulse voltage stimulated windings. Additionally, a respective design also ensures simple production processes and enables very high mechanical winding strengths. Furthermore, they can be used as an earthing tape.
