Researchers from the SAS Institutes of Electrical Engineering and Materials and Machine Mechanics have managed to develop technology for the production of the lightest superconducting cable in the world. The superconducting effect can be used in many applications, and in some of them, such as the space, aerospace and power industries, for several reasons, are required. This lightweight superconductor enables higher energy efficiency, lower energy consumption, higher speeds and acceleration in moving devices. This wire can therefore represent a breakthrough in the development of lightweight wind turbine generators located in offshore seas, superconducting levitation drives, and in the space program could one day actively shield humans from cosmic rays.

“A superconductor is a material that exhibits zero electrical resistance at low temperatures and is therefore the perfect conductor capable of carrying huge currents. “, said Ing. Pavol Kovac, DrSc. from the SAS Institute of Electrical Engineering.

A superconducting wire is composed of a metal-sheathed superconducting core that forms the major part of the wire mass. "We have developed a new type of ultra-light superconducting wire with MgB2 core, a thin titanium interlayer and a special composite aluminium (Al) sheath, called HITEMAL®," said Ing. Martin Balog from the SAS Institute of Materials and Machine Mechanics. (mh)
