About Us

SuperPower Inc. is a leading manufacturer and provider of second-generation high-temperature superconducting (2G-HTS) wires. For the past 10 years or more, we have provided, and contributed to, many solutions to various advanced applications and projects for our customers.

2G-HTS wires, unlike the conventional copper conductors, can transport the current with no resistivity, ultimate zero- ohms: This means that the power devices can be shrunk down to very compact sizes with no Joule-heats, when it is operated under cryogenic temperatures (77K, 30K, 4.2K, for instance). Our partners, by using our wire, have demonstrated very-high-current cables capable of more than 10 thousand Amperes, or advanced magnets of ultra-high field more than 40 Tesla.

Such high-power cables and superb coil-magnets will serve for future systems such as next generation NMRs for advanced bio-medical sciences, compact fusion reactors to solve climate changes. Future mobility will come true by HTS- hover transportation, electric-airplanes, or space-aircrafts. Thus, our 2G-HTS wire will contribute to the following sustainable development goals (SDGs).
Since February 2012, SuperPower Inc. has been a wholly owned subsidiary of Furukawa Electric. Co., Ltd. In Japan, who is striving for various SDGs, with its established solutions to energy, mobility, and, information. Our essential goal is to contribute to safe, peaceful, and rewarding life on our planet Earth.
