ASTA winding wires made out of copper are diverse and omnipresent in energy production and energy transmission.

Starting with energy generation, ASTA Roebel bars are used for generator windings. Transformers of the medium to high performance classes are equipped with ASTA continuously transposed conductors for energy transmission over long distances. Other applications for ASTA components are, for example, industrial and traction transformers, pumping systems and wind power generators.
