Superconductors Have No Electrical Resistance

The mechanisms of superconductivity in ceramics are not fully understood, and most progress is still being made by trial and error. Perhaps once the secrets are unlocked, the many obstacles posed by ceramic superconductors 

Inner cryostat wall Liquid nitrogen coolant Copper shield wire 

HTS shield tape High voltage dielectric HTS tape Copper core 

High lemperauire Superconductor (HTS) materials arc wound within a cable systein designed to also contain liquid nitrogen coolant. 

I hermoset plastics (Section 12.4) are pretty tough, as are various polymeric
