Superconducting conductors

Superconducting Conductors

Superconductivity is a phenomenon where some materials exhibit no electrical resistance below certain cryogenic temperatures. For this reason, superconducting wire can carry more than one hundred times the current of an equivalent size of copper wire. Power devices using superconducting technologies benefit from up to 8% efficiency improvement, because they have zero resistance to direct current electricity.

These attributes can translate into significant reductions of cost, size and weight for motors, generators and power cables. Superconducting technologies will play a crucial role in the electric power industry: from power generation (e.g. offshore superconducting wind turbine generators) to transmission and distribution (e.g. high power superconducting cables, superconducting fault current limiters (SFCL), superconducting magnetic energy storage (SMES) and superconducting transformers), to end use (e.g. superconducting industrial motors, generators and condensers and high-field magnets).
