BAND SUPERCONDUCTING ELEMENT WITH IMPROVED OWN PROTECTION IN TRANSITION FROM SUPERCONDUCTING STATE TO NORMAL ONE Russian patent published in 2017 - IPC H01L39/08 

FIELD: electricity.

SUBSTANCE: superconducting element comprises a metallic substrate, an insulating layer located between the substrate and the superconducting layer, an insulating layer, a superconducting layer, and a metal protective layer, the insulating layer in the cross section of the superconducting element projecting at both ends beyond the portion (B_SL) of a substrate coated with the superconducting layer. The insulating layer galvanically separates the superconducting layer and the metal protective layer from the substrate and that the thickness (D) of the insulating layer is selected such that the superconducting element has a transverse breakdown voltage from the metal substrate to the superconducting layer and to the metal protective layer of, at least, 25 V.

EFFECT: providing the possibility to reduce the risk of damage in case of transition from the superconducting state to the normal one.
