Development of high performance Ag sheathed Bi2223 wire

“…Unfortunately, our attempts to sinter the YBCO lms on the Ag substrate at such high temperature failed, due to a damage of the layer. On the other hand, the thallium and particularly BiSCO superconductors can be typically sintered at lower temperatures and silver is successfully applied for manufacturing the superconducting tapes [6]. Silver also enables using high pressures for pressing the superconductors, which is very important for achieving the good quality polycrystalline superconductor.…”

The YBa2Cu3O δ lms were obtained directly on the polished silver substrates by the sedimentation process.Thickness of these lms is of the order of several tens micrometers. The temperature dependences of the resistance and the AC susceptibility of the lms were measured and analyzed. The critical temperatures of these specimens vary from 89 K to 91 K and they do not depend on the annealing temperatures. The critical currents were calculated from AC susceptibility measurements using the Bean's model.

“…The pressure was 30 MPa at a maximum, and functions not seen in prior high-pressure reactors, including improvements in oxidation partial pressure and precise thermal uniformity, were added [8].…”

SUMMARYA three-in-one HTS cable has been developed. Its cable core is composed of a conductor and a shield wound with BSCCO and electrical insulation of the PPLP. The three cable cores are covered in thermal insulated stainless corrugated pipes. The BSCCO wires represent a dramatic innovation by virtue of a newly developed process named Controlled Over-Pressure (CT-OP). As a new cable technology, a 350-m thermal insulation pipe was tested for 7 months to find that the life of the vacuum intensity is more than 10 years. The HTS cable with tension members was designed for installation into an underground duct. In addition, a fault current of 23 kA, 0.63 s, was applied to a sample cable with no damage to the BSCCO wires or the cable insulation. These technologies will be applied to the Albany project in the USA.
