About ASTA

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.

At our location in Oed, Austria, wire is produced since 200 years 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 - Advanced Solutions for Technical Applications

ASTA products are integrated into the biggest transformers and generators. Examples include the Three Gorges Dam in China, the biggest hydroelectric power station.

ASTA has an approximate 40% share of the European market and around 20% world market share.

The service life of a transformer depends on the quality of the insulation. Therefore, 80% of the necessary insulation is applied in the ASTA plant.

90% of ASTA customers are longstanding regular customers of the company.

Numerous patents have arisen from the close working relationship with our customers, for example the netting tape or the TG continuously transposed conductors.
