Divertor Tokamak Test facility (DTT) has signed a supply contract with Kiswire Advanced Technology (KAT), a South Korean company specialised in superconducting wires, for the supply of 18.4 tonnes of Niobium-Tin (Nb₃Sn) strands to be used in the conductors of the central solenoid and the poloidal field magnet PF1 of the DTT.

The contract requires the production of strands meeting high-performance specifications: 270 Amperes at 12 Tesla and 4.2 Kelvin, with hysteresis losses under 500 mJ per cm³, in accordance with the technical specification defined in the tender.

KAT is a key global supplier in the superconducting market and is already contributing to major international tokamak and high-energy physics projects such as KSTAR, ITER and CERN. This contract reflects DTT’s commitment to excellence and its openness to international markets for advancing fusion energy as a clean and sustainable power source.
