• 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
