The SuperRail project will be one of the world’s first installations of superconductors in railway systems.

Superconductivity for rail electrification

Superconductivity for rail electrification

The consortium comprising Absolut System, Nexans, CentraleSupelec & the University of Lorraine, supported by SNCF Réseau, will enable manufacturers to master the unwinding of a superconducting cable in a railway environment with constraining bending radii, and to install an innovative, energy-efficient cooling system technology.

Initially, in order to make the superconducting solution viable in the short term, Absolut System will supply a PTC1000 for the demonstrator.

This cryogenic cooler is based on Pulse-Tube high-power technology. This solution, currently available, will be used to demonstrate energy transport in hyper-constrained zones. It can also be used outside the rail sector. In parallel with the installation of the superconductivity demonstrator, and in order to offer a more cost-effective and reliable long-term solution, Absolut System will be developing a new generation of Stirling-type chillers.

Absolut System’s innovation overcomes technological hurdles to design a cooler that consumes less energy, is highly reliable and requires little maintenance, thanks to non-contact hydrodynamic bearing technology fully adapted to intensive use.
