  2. Superconducting wire - Wikipedia

    en.wikipedia.org/wiki/Superconducting_wire

    Critical temperature T c, the temperature below which the wire becomes a superconductor; Critical current density J c, the maximum current a superconducting wire can carry per unit cross-sectional area (see images below for examples with 20 kA/cm 2). Superconducting wires/tapes/cables usually consist of two key features:

  3. Tri-rated cable - Wikipedia

    en.wikipedia.org/wiki/Tri-rated_cable

    Tri-rated cable is a high temperature, flame retardant electrical wire designed for use inside electrical equipment. Tri-rated cable meets the requirements of three different international standards: BS 6231, UL 758, and CSA 22.2. [ 1 ]

    Sag Comparison Test Data: temperature vs. sag of various conductor types on a 215' test span. Operation at high temperatures implies high line losses, which may be uneconomical, but the ability to carry such current contributes to the redundancy of the electric grid (the high overload capacity can stop a potential cascading failure ) and thus ...

    2 S) at extremely high pressures (around 150 gigapascals) was first predicted and then confirmed to be a high-temperature superconductor with a transition temperature of 80 K. [66] [67] [68] Additionally, in 2019 it was discovered that lanthanum hydride (LaH 10) becomes a superconductor at 250 K under a pressure of 170 gigapascals. [69] [68]

    The company operates across three primary business segments: production of high-temperature superconductor (HTS) wire, which has a significantly higher electrical current capacity than copper wire; development of HTS-based motors and generators; and design and manufacturing of power electronic systems for wind farms and transmission systems. [5]

  7. Electrical wiring - Wikipedia

    en.wikipedia.org/wiki/Electrical_wiring

    A wire or cable has a voltage (to neutral) rating and a maximum conductor surface temperature rating. The amount of current a cable or wire can safely carry depends on the installation conditions. The international standard wire sizes are given in the IEC 60228 standard of the International Electrotechnical Commission.
