HTS wire
Using high-temperature superconductors cables with higher transmission capacities, smaller cross sections and lower transmission losses can be built.
Commercial quantities of HTS wire based on BSCCO(Bismuth strontium calcium copper oxide) are now available at around five times the price of the equivalent copper conductor BSCCO wire requires an expensive batch production process and relatively high quantities of silver. YBCO coated conductors is being manufactured in in a semi-continuous process. Manufacturers are claiming the potential to reduce the price in volume to 50% to 20% of BSCCO.

Testing of an HTS Power Cable
prototype high
temperature superconducting (HTS) power cable made from
second-generation YBa2Cu3Ox (YBCO)-coated conductor tapes has been produced. testing of the HTS cable included determination of the
V-I curve with a critical current of about 2100 A and AC testing of the cable was conducted at currents up to about 1500 Arms. Over-current testing
was conducted at peak current values up to 4.9 kA and pulse lengths upto .3 to .5 sec. The commercial grade
HTS cable demonstrated the feasibility of secondgeneration
YBCO tapes in an ac cable application.
