Maximum transmission capacity and near-zero losses

Transport, heating and industry will all need to be electrified in the coming years if net zero goals are to be achieved. Cities will see the biggest increase in electricity demand, so finding ways to boost urban power supplies is a priority. Superconducting cables make it possible to transmit massive amounts of electricity in a very small space, making them the perfect candidate for congested urban grids.

Our market-proven superconducting cables are transforming urban power. These compact cables allow grid operators to transfer more power at medium voltage, while reducing land take, cutting the amount of capital equipment and eliminating heating and electric and magnetic fields (EMF).

How can Nexans solutions help?

Nexans is the global leader in the design and manufacture of both superconducting cable systems and superconducting fault current limiters (SFCLs). We provide end-to-end superconducting solutions, from initial concept to deployment and commissioning. And we back this up with expert services and support.

Unique capabilities - our resources include a complete portfolio of technological assets, industrial tools and expertise. High-Temperature Superconducting (HTS) cable R&D, engineering, manufacturing and testing are carried out in Hanover in Germany with the support of our plants in France and Norway for some operations. HTS cable accessories and terminations are developed in Calais in France.
Technological leadership - Nexans is the world leader in the field of flexible cryogenic envelope technology - a vital asset for superconducting cable systems. This builds on our decades.long experience in the design and manufacture of insulated flexible lines for the transport of cryogenic fluids.
Superconducting standards - Nexans is playing a key role in the development of new standards through its membership of TC 90, the committee of the International Electrotechnical Commission (IEC) dedicated to the preparation of international standards relating to superconducting materials and devices. Nexans currently chairs the TC 90 committee.

Our unique capabilities in R&D, innovation, testing, manufacturing and deployment mean that we are perfectly placed to assist our customers as they prepare to take advantage of the opportunities offered by superconducting systems.
