“…For instance, at the Superconducting Cable Project [11] in Albany, NY, which Sumitomo Electric Industries is participating in, a 350-m-long superconducting cable is connected to a real power system, and the reliability and practicality of the superconducting cable are being confirmed. During a fault, a current up to 23 kA can flow through the superconducting cable.…”

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.

“…From standard coaxial theory, the inductance per unit length of a two-layer cable is the sum of the self inductance of each layer and the mutual inductance between them or (1) where the contribution of each inductance was determined assuming an equal current distribution in the inner and outer tape layers. Olsen [9] derived analytical expressions of the inductances in a multilayer cable taking into account the twist pitch of each layer…”

The impact of Ni-5at%W substrates on ac loss and inductance of HTS cables was examined. Two 1.2-m prototype cables were made with stainless steel laminated BSCCO tapes and were wound on a 25.4 mm diameter former. Each cable consisted of two layers of 15 BSCCO tapes wound at opposite lay angles and has an estimated critical current of 3000 A at 77 K. One cable had four additional layers of 4.8 mm wide Ni-5at%W tape co-wound with the BSCCO tapes to simulate a commercial second generation HTS cable. The Ni-5at%W tapes had the same width as the BSCCO and a thickness of 50 microns. Through the use of a coaxial copper ground, the cable inductance was measured at room temperature and liquid nitrogen (77 K) using high frequency rf measurement techniques. Experimental results for the cable inductance and ac loss were compared against numerical calculations to determine the significance of the Ni-5at%W substrate contribution. Results indicate that inductance and ac loss changes from these substrates in commercial cables should be small.
