Recently, deposition of REBCO layer on thinner C276 Hastelloy substrate for the second generation high temperature superconductors (2G HTS) wires have attracted more attentions. The main advantages are i) to effectively increase the critical engineering current (Je) without additional efforts on enhancement of current carrying capacity in the superconducting layer, ii) to improve the...

High temperature superconducting (HTS) conductor on round core (CORC) cable is considered as a potential technology for power applications, because of its high current-carrying capacity, compactness, and strong mechanical properties. As the main component of CORC cable, the center core is used to support the HTS conductors. However, for metal center core, the eddy current induced in the core...

The enhancement of engineering current density, Je is one of important issues in conductors for high performance superconducting magnets. In order to obtain the higher Je of high temperature superconducting (HTS) REBCO conductor, we adopted the laminate structure consisting of three REBCO superconducting layers on one common IBAD processed substrate. In this study, we have fabricated various...

Various large current-carrying conductors composed of REBCO tapes have been proposed in recent years for high current applications such as magnets and power transmissions. As one of the conductors, a twisted stacked-tape cable (TSTC) is being developed at the Massachusetts Institute of Technology. The TSTC conductor is composed of stacked REBCO tapes which are twisted along the longitudinal...

We have fabricated Hf and La doped FF-MOD GdBa2Cu3Oy (Gd123) thin films on LaAlO3 substrates and investigated their flux pinning properties. Temperature dependence of Jc in magnetic fields parallel to the c-axis orientation up to 7 T was estimated from the width of the magnetization curves using the modified critical state model. Critical temperature for Gd123 thin films indicated around 92 K,...

We investigated the pinning centers formation in Sm1Ba2Cu3O7-d(SmBCO) coated conductor by reactive co evaporation method. The SmBCO film was deposited on the IBAD-MgO template with the structure of SmBCO/LMO/MgO/Y2O3/Al2O3/Hastelloy using EDDC (Evaporation Using Drum in Dual Chambers) process. We investigated the phase formations as pinning centers with the change of composition ratio of...

In practical applications, the critical current of high temperature superconducting (HTS) tapes is usually influenced by many factors, such as magnetic field, stress and strain, etc. In order to design HTS devices accurately, it is vital to study the critical current behavior of HTS tapes under different conditions. In this work, a series experiments have been performed to study the critical...

This paper introduced a insulation design for a 10kV three-phase concentric high temperature superconducting cables by cold dielectric method. Insulation properties of the PPLP (Polypropylene laminated paper) and its dielectric strengths un-der AC voltage endurance test and the lighting test in liquid ni-trogen have been studied. According to test results and the standard for 10kV paper...
