Superconductor Technology for Sustainable Power Grids

Higher Transmission Capacity. Improved Short Circuit Protection. Facilitated Grid-Expansion.

Superconductor Activity

Nexans is one of the largest cable manufacturers worldwide and has a leading position in the superconductor industry. Superconductors have no electrical resistance and transmit large amounts of electrical power practically without losses. These technical properties open up fundamentally new opportunities in power engineering.

Nexans develops and manufactures power equipment based on superconductors. We supply solutions for upgrading, expanding, and building sustainable electric grids: 

Superconducting cable Nexans supplies compact, very-low-impedance superconductor cables, which combine high electric power transmission capacities and minimized space requirements. These cables greatly facilitate modernization work on electricity supply infrastructures in congested urban areas and provide a cost-effective means of upgrading stressed sections of high voltage grids. Our superconductor cable systems can be utilized to construct gigawatt-range transmission capacities at grid-interconnecting hubs and also enable efficient, space saving high current transmission for technical purposes.

Nexans SFCL Vattenfall night Superconducting Fault Current Limiters (SFCL) by Nexans protect electrical power grids and their operating equipment against damage by short circuit currents. Grids can be operated at higher loads if equipped with this innovative protection technology. Coupling grids and infrastructural meshing at a larger scale are enabled while operational flexibility improves. Moreover, Nexans SFCLs minimize premature wear of conventional grid equipment and provide a sound solution for incorporating distributed power generation devices even in difficult grid environments of limited load-carrying capacity.

 For superconductor power technology trials we employ proprietary high current and high voltage test fields which are also available to our customers for research and development purposes.
