ASTA Elektrodraht GmbH

ASTA manufactures high-quality insulated winding material made of copper for electrical engineering in the high-energy sector, so-called Roebel bar conductors for transformers, and Roebel rods for generators. In these areas, ASTA occupies a leading position worldwide.

At our location in Oed, Austria, round wire is formed into flat wires and shaped with hundredths of millimeter accuracy, to customer specifications, insulated with special lacquer, paper or mesh tape and processed into bundle conductors.

Globally active large corporations, such as ABB, SIEMENS, GE, are satisfied regular customers of ASTA. The company focuses on quality and not on volume. As a result, ASTA is able to fulfill individual customer requests promptly and to offer tailor-made solutions.

Starting with power generation, ASTA Roebel Rods are used in generator windings. In the field of long-distance energy transmission, transformers of the medium and higher power classes are equipped with ASTA Roebel bar conductors. Other applications for ASTA components include, e.g., industrial and traction transformers, large motors for paper machines and pumping stations or wind power generators.
