kA-Class High-Current HTS Conductors and Windings for Large Scale Applications

Abstract:

Article Preview

Multistrand conductors with kA-class current capacity are a key requirement for many large scale applications of HTS in power engineering and magnet technology. Siemens has developed a cabling technology for continuously transposed conductors (CTC) for transformer and generator applications with critical current up to 1.2 kA at liquid nitrogen temperature. For technical issues of coil winding several demonstrator coils were fabricated in solenoid and racetrack geometry. The current capacity of the CTCs and of the coils are in agreement with model calculations considering magnetic field distributions within the conductor and coils, respectively. To account for mechanical loads during operations such as Lorentz forces and centrifugal forces robust conductors are required. We constructed dedicated devices in order to study the performance of continuously transposed conductors in coil-like geometry.
