- Low Temperature Superconductors : Require cooling below LHe temperature
→Practical use in conventional superconducting applications - High Temperature Superconductors : Indicate superconductivity above LN2 temperature
→Verification stage for practical use
Bismuth (Bi) - - - the 1st generation (1G)
Yttrium (Y) - - -the 2nd generation (2G)
-Higher operating temperature than LTS. (No liquid helium is required.)
-Higher critical current at higher magnetic field
-Smaller and lighter compared with current equipment

Fujikura has been developing its original techniques for coil winding and succeeded in development of the world's largest yttrium-based high-temperature superconducting magnet with a 20-cm-diameter room temperature bore in 2012.
- Total wire length : 7200 m (300m x 24 layers)
- Total number of turn : 5775
- Operating current : 333 A @ 25 K
- Center magnetic field : 5.0 T (50000 Gauss)
- Stored energy : 426 kJ

Fujikura has been developing superconducting power cables and verified quadruple lower AC Loss than conventional power cables by applying higher critical current HTS wires.
- Single-core in one pipe cable system /66kV-5kA /10m class long
- Wire performance : Ic > 240 A/4mm-wide @77K,Self-field
- Target AC loss : < 2 W/m @5kA
- Measured AC loss : 1.4W/m@77K, 0.95W/m@67K
