SuperPower has been developing (RE)BCO-based 2G HTS wire at its manufacturing plant in Schenectady, NY since 2000 and is now routinely producing long lengths of high performance wire that is being shipped to customers around the world for a wide range of applications.
SuperPower®2G HTS Wire is produced in an automated, continuous process beginning with an inexpensive high strength metal alloy “tape” as the base substrate material and adding buffer layers, ceramic-based superconductor material and protective overlayers.
Once the wire has been slit into device-specific widths, Surround Copper Stabilizer (SCS) is applied to completely encase the wire. Overcurrent capability in SCS wire can be tailored to the specific application. The stabilizer protects the conductor and produces rounded edges that are beneficial for high-voltage applications. Further, the probability of failure in the device due to voltage breakdown is reduced in wire with SCS. SuperPower’s SCS has been successfully implemented and tested on continuous lengths of hundreds of meters of wire.
