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:
The suburban Long Island electrical substation is fed by a 2,000 foot (600 m) underground cable system which consists of about 99 miles (159 km) of high-temperature superconductor wire manufactured by American Superconductor chilled to −371 °F (−223.9 °C; 49.3 K) with liquid nitrogen, [dubious – discuss] greatly reducing the cost ...
Depending on the clearance and the design of the machine where the cartridge heater will be inserted, the type of wire used will vary. Fiberglass is the commonly used for cartridge heaters and other high-temperature applications, [10] such as automotive wiring harnesses and industrial
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.

High-temperature superconductivity (high-T c or HTS) is superconductivity in materials with a critical temperature (the temperature below which the material behaves as a superconductor) above 77 K (−196.2 °C; −321.1 °F), the boiling point of liquid nitrogen. [1]
Nichrome, a non-magnetic 80/20 alloy of nickel and chromium, is the most common resistance wire for heating purposes because it has a high resistivity and resistance to oxidation at high temperatures, up to 1,400 °C (2,550 °F). When used as a heating element, resistance wire is usually wound into coils.
