ASTA manufactures high-quality insulated winding material made of copper for use in electrical machinery in the high-energy sector, so-called conductors (CTC) for transformers, and Roebel bars for generators. ASTA has a top position worldwide in these areas.
Round wire is produced at four locations in Austria, India, China and Brazil at a dimension that is specified by the customer. It is formed accurately down to one hundredth of a millimetre, insulated with special enamel, paper or a netting tape and transposed to CTCs.
ASTA has become synonymous with highquality copper components that are used exclusively for transformers and generators in the high-energy sector.
ASTA has an approximate 40% share of the European market and around 20% world market share.
Numerous patents have arisen from the close working relationship with our customers, for example the netting tape or the TG continuously transposed conductors.
