Core offering

SuperOx designs, manufactures, and sells high-temperature superconductor (HTS) equipment for electric power, scientific research, and medical industries. The core product lines are HTS wires and cables, superconducting fault current limiters (SFCL), and high-field HTS magnets. Solutions are custom-engineered to customer specifications and are deployed in utility grids, fusion reactors, scientific facilities, and medical imaging systems.

Product overview

SuperOx is a world leader in developing and implementing equipment based on high-temperature superconductors (HTS) for the electric power industry, science, medicine, and other industries. The company's product portfolio consists of three core product lines: High-Field HTS Magnets for scientific and medical applications including fusion and MRI; Superconducting Fault Current Limiters (SFCL) for electrical grid protection; and HTS Wire/Cable products including Standard HTS Wire, Heavy Current HTS Wire, Reinforced HTS Laminate, Ultralight HTS Laminate, and Ultra-High Current HTS Cable. Since 2014, SuperOx has been developing HTS wires with the technology to manufacture wires with record current-carrying capacity (over 200A per 4mm width) and increased adhesive strength.

Partnerships

One partnership is on record.

• Commonwealth Fusion Systems (CFS)coreTechnology or Integration · 19 December 2025SuperOx is identified as a key Russian supplier of high-temperature superconducting wire for Commonwealth Fusion Systems' SPARC reactor project. CFS's SPARC reactor alone requires 10,000 kilometers of superconducting wire. However, the future viability of this supply relationship is noted as uncertain following the 2022 invasion of Ukraine, representing a significant geopolitical risk for CFS's supply chain.
