Scope

This standard provides the general characteristics of practical superconducting wires and provides application guidelines for the mechanical, electrical, and superconducting property testing methods of practical superconducting wires. Practical wires refer to wires that can be commercially mass-produced in sufficient lengths and used in the manufacture of equipment.
This standard particularly focuses on the characteristics of practical superconducting wires that differ from conventional copper and aluminum wires.
This standard applies to a variety of superconducting wires described in GB/T 2900.100-2017, including single-core, multi-core superconducting wires, composite superconductors and coated conductors, as well as other integrated structure composite superconducting wires.
This standard does not apply to wires other than practical superconducting wires (such as prototypes, samples, and wires in development), as well as conductors composed of multiple wires (such as cables).
