High Power Density. Easy Processing. New Possibilities.
THEVA Pro-Line is our high temperature superconductor (HTS) wire. It is characterized by extremely high current carrying capability offering unsurpassed current and power densities for various applications. It is produced in our industrial production line in Germany under highest quality standards.
Structure of THEVA Pro-Line HTS wire
Our THEVA Pro-Line HTS wire is designed for best performance in different applications. Therefore, we produce our wire layer-wise on a non-magnetic steel substrate. The first layer is an isolating MgO layer which we vaporize via our patented ISD process. A cap layer completes the MgO layer. Both layers preset a crystalline orientation which will be adopted by the following superconductor layer. This orientation improves the crystalline structure and therefore current carrying capacity of the superconductor. Subsequently, a silver layer is vaporized as a contact layer. Tailored to the later application of the wire, a copper surround coating or a copper lamination serves as electrical as well as mechanical stabilization.
Properties of our HTS wire
The sophisticated design of THEVA Pro-Line HTS wire results in good mechanical and magnetic properties. Small bending radii, high tensile strength as well as an extraordinary performance in magnetic fields characterize the wire. You may find details in the linked datasheets on the right-hand side of this page and our general properties brochure.

THEVA cooperates with the Israeli company Quantum Experience Ltd., who manufactures and sells superconductor experiment kits and show kitchen sets under the brand name of “Quantum Levitation”. The experiments show the unique physical properties of magnetic levitation of superconducting materials. THEVA Pro-Line HTS wire is used to manufacture the levitators. The sets have been specially developed for use in schools, universities and other educational institutions.
With this knowhow, we can develop and produce coils of different sizes and performances. The maximum size for coils is currently 1.4 m (4‘7“). Depending on the application, different potting compounds can be used to stabilize the windings and enable efficient cooling.
One example for the application of superconducting coils from THEVA is the EU project EcoSwing, where a 3.6 MW wind turbine generator was developed and built. The use of THEVA coils resulted in a lower size and weight of the generator.
TAPESTAR-Family: Quality Management for Coated Conductors.
The TAPESTAR™ enables rapid, high-resolution quality inspection for superconducting tape. By means of a non-contact measurement method, the device produces continuous scans of the critical current along the tape with millimeter resolution, also enabling reliable detection of local faults and non-uniformities in the superconducting coating.
The measurement method can be used for all types of HTS superconducting tape (1G or 2G) and works independently of their magnetic properties – also for thick laminated or insulated tapes where electrical contact is unavailable. Many laboratories and well-known tape producers rely on this method.
The TAPESTAR™ is available in two versions. The TAPESTAR™ XL is suitable for quality control in a production environment or incoming inspection of goods. The smaller version TAPESTAR™ is ideal for lab use. Both versions can be customized for various different tape widths.
NEW Features for our Tapestar XL™ series:
- Tapestar ™ XL-HF for measurements up to 1 T @ 77 K
- Tapestar ™ XL-W for tapes with widths up to 40 mm
- Optional for all systems: Inkjet printing for comfortable marking, enabling exact correlation of Tapestar data and real tape positions
These features might be available as a retrofit solution for your existing Tapestar ™ XL or can be purchased with a new Tapestar ™ XL device.
