Researchers at Florida State University’s Center for Advanced Power Systems (CAPS), in collaboration with Colorado-based Advanced Conductor Technologies, have demonstrated a new, ready-to-use superconducting cable system — an improvement to superconductor technology that is driving the development of technologies such as electrically powered ships or aircraft.
In a paper published in Superconductor science and technologyIn this article, the researchers demonstrated a system that uses helium gas for necessary cooling. Superconducting cables can move electric current without resistance, but they need extremely cold temperatures to function.
“We want to make these cables even smaller, using less weight “And the volume is lower,” said Sastri Bamedi, co-author of the paper, professor of engineering at FAMU-FSU and co-director of CAPS. The next generation of superconductor technology. “
Previous work showed that a corpse Superconducting cables It can be cooled with helium gas, but the ends of the cables need another medium for cooling, such as liquid nitrogen. In this paper, the researchers overcame that hurdle and were able to cool an entire cable system with helium gas.
The work gives engineers more design flexibility because helium remains a gas over a wider temperature range than other media. Liquid nitrogen, for example, is not a suitable refrigeration medium for some applications, and this research moves superconductivity technology closer to practical solutions for those scenarios.
The paper is the latest result of a partnership between researchers at CAPS and Advanced Conductor Technologies (ACT). Previous teamwork led to other publications and to the development of Conductor Cables on the Round Core (CORC) which was the subject of this research.
‘removing the need to liquid nitrogen To pre-cool the existing wiring of the superconducting cable and use it instead Helium gas The cooling of the cable has allowed us to make an ultra-compact superconducting power cable that can run in continuous mode, said Danko van der Laan, founder of ACT. “So it has become a neat system that is small and lightweight and allows you to more easily integrate into electric ships and aircraft.”
