ASTA products are built into the biggest transformers and generators worldwide. 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 is dependent 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.
