Nexans and SNCF Réseau launch an innovative superconducting current limiter

Nexans and SNCF Réseau are joining forces to introduce a superconducting current limiter (SFCL) to the rail market. The first of its kind, this device aims to strengthen the security and reliability of the network by limiting electrical disturbances.

Intended for the Belfort region, the SFCL is installed in the Bussurel substation. It offers autonomous reduction of short-circuit currents, regenerating in less than five minutes without human intervention.

The benefits are numerous: improved reliability, infrastructure optimization and long-term cost reduction. This project illustrates both companies' commitment to innovation and sustainability.

This partnership is part of a broader strategy to modernize electricity networks and promote the energy transition in rail transport.
