“…High-temperature superconducting (HTS) power cables are suitable for high-load areas such as dense urban districts of large cities, where construction of additional substations could be cost-prohibitive [1][2][3][4]. HTS power cables could transfer a considerable amount of power compared to traditional low-capacity cables.…”

Bypassing transient current through copper (Cu) stabilizer layers reduces heat generation and temperature rise of high-temperature superconducting (HTS) conductors, which could protect HTS cables from burning out during transient conditions. The Cu layer connected in parallel with HTS tape layers impacts current distribution among layers and variations of phase resistance in either steady-state or transient conditions. Modeling the multilayer HTS power cable is important for transient studies. However, existing models of HTS power cables have only proposed HTS cables without the use of a Cu-former layer. To overcome this problem, the authors proposed a multilayer HTS power cable model that used a Cu-former layer in each phase for transient study. It was observed that resistance of the HTS conductor increased significantly in the transient state due to a quenching phenomenon, which made the transient current mainly flow into the Cu-former layers. Since resistance of the Cu-former layer has a significant impact on the transient current, detailed modeling of the Cu-former layer is described in this study. The feasibility of the developed HTS cable model is evaluated in the PSCAD/EMTDC program.

Superconducting technology for aerospace application is enabled by emerging development around hydrogen cooled electrically powered aircraft, aiming at zero-emission aviation. Superconductors, typically in the form of tape or wire in a composite architecture, can not only carry current density which is over 100 times that of copper and aluminium, but are also characterized by much lower losses. This property of superconductors makes them good candidates for the fabrication of superconducting devices of high specific power density, i.e. lower size and lighter weight, which is critical for aerospace applications. Superconductors, like any other conductors, require standard insulation to function safely and reliably in the electrical apparatus of aircraft, especially due to the special architecture, operating temperature, and operating condition of superconducting apparatus at high altitude. Extra attention should be drawn to choose proper insulating materials for such applications. In this paper, the challenges and considerations for choosing insulating materials for superconducting devices in cryo-electrified aircraft are reviewed and discussed.
