Progress in high temperature superconductor coated conductors and their applications
Alexis P. Malozemoff,Steven Fleshler,Martin W. Rupich,Cornelis Leo Hans Thieme,Xiaoping Li,Wei Zhang,Alexander Otto,J. Maguire,Douglas C. Folts,Jie Yuan,Hans-Peter Kraemer,W Schmidt,M. Wohlfart,H.-W. Neumueller +13 more
TL;DR: In this paper, a 2G high temperature superconductor (HTS) wire with a coated conductor technology is proposed for fault-tolerant HTS cable, which can achieve high resistance in quenched state during a fault event and at the same time provide significant heat capacity to limit the temperature rise.

TL;DR: In this paper, a practical superconducting conductor based upon biaxially textured HTS coatings is described. But the method for producing flexible and bend strain-resistant articles and articles produced in accordance therewith are described which provide improved current sharing, lower hysteretic losses under alternating current conditions, enhanced electrical and thermal stability and improved mechanical properties between otherwise isolated films in a coated HTS wire.
