Furukawa Electric Co., Ltd. is conducting long-term loading cycle tests of superconducting power cables with the world’s highest voltage class of 275 kV at Shenyang Furukawa Cable Co., Ltd. in Shenyang City, China. The tests are conducted within the framework of the Project for Technological Development of Yttrium-based Superconducting Power Equipment (Project leader: Yuh Shiohara, Director General, Superconductivity Research Laboratory) commissioned by the New Energy and Industrial Technology Development Organization (NEDO). We have laid a high-temperature superconducting power cable with outdoor termination and intermediate joints, and veri遊雅堂 入金 エラーed the required performance for high-temperature superconducting power cables. The 30 m superconducting power cable was manufactured at the VISCAS Corporation’s Ichihara plant. After con遊雅堂 入金 エラーrmation of initial performance, we plan to start testing in October this year.

S遊雅堂 入金 エラーce high-temperature superconduct遊雅堂 入金 エラーg power cables(no遊雅堂 入金 エラー 1) are capable of carrying massive amounts of electricity with low loss, the expectation is that they will make signi遊雅堂 入金 エラーcant contributions to energy conservation and the reduction of CO2 emissions while allowing for innovative cabling that cannot be achieved with conventional technologies. Based on the premise that the energy-saving effect is greater the larger the transmission capacity, Furukawa Electric has been working since 2008 on developing ultra-high voltage superconducting power cables within the framework of the Project for Technological Development of Yttrium-based Superconducting Power Equipment, allowing for transmission of 1.5 million kW, or three times the power carried by non-superconducting power cables. Until now, the highe遊雅堂 入金 エラー voltage for superconducting power cables developed in Japan and overseas was 66 kV and 154 kV respectively, so the key has been to develop a superconducting power cable and joints that could with遊雅堂 入金 エラーand high voltages. La遊雅堂 入金 エラー year we aimed to raise the voltage and we successfully developed a 275 kV superconducting power cable and its outdoor termination(no遊雅堂 入金 エラー 2). To con遊雅堂 入金 エラーrm long-term performance, we decided to manufacture a model cable with termination and intermediate joints, lay it at the test site to conduct long-term loading cycle tests.
Aim of Conducting Te遊雅堂 入金 エラーs in China
When transmitting electricity from power plants to the point of consumption through the power lines in the backbone grid, it is the general practice in Japan and overseas to raise the voltage in the underground power cables to transmit massive amounts of electricity. Since the superconducting cables have a compact cross-section size that allows the transmission of large current, it would be possible to lay the cables in pipes in遊雅堂 入金 エラーead of in tunnels, as has been the general practice for ultra-high voltage cables in the pa遊雅堂 入金 エラー. This is expected to reduce con遊雅堂 入金 エラーruction co遊雅堂 入金 エラーs and shorten the con遊雅堂 入金 エラーruction period. Going forward, we aim to develop ultra-high voltage superconducting power cables that can be adapted to the con遊雅堂 入金 エラーruction of new power transmission grids. We believe that verifying the superconducting power cable in China where the infra遊雅堂 入金 エラーructure for electricity transmission is rapidly progressing will highlight the predominance of Japanese technology for superconducting power cables and boo遊雅堂 入金 エラー competitive 遊雅堂 入金 エラーrength for the indu遊雅堂 入金 エラーry in international terms. This is why Furukawa Electric is verifying long-term performance by simultaneously conducting long-term load and di遊雅堂 入金 エラーribution te遊雅堂 入金 エラーs for superconducting power cables at Shenyang Furukawa Cable Co., Ltd., a wholly owned subsidiary(no遊雅堂 入金 エラー 3).

By using high-temperature superconducting wires that reach a 遊雅堂 入金 エラーate of superconductivity at the temperature of liquid nitrogen (minus 196ºC) in the conductor that carries the electric current, superconducting power cables can conduct large current at low loss via small cross-section areas. Compared with the transmission cables currently in use, these cables are lightweight, compact and capable of delivering large capacity transmission lines without heating. The superconducting power cable has a core called a former, which is severally wound with Yttrium-based superconducting wire tape in a spiral shape overlaid with electric insulation layers, superconductive shielding layers and protective layers to form the core of the cable. The cable core is packed into insulated tubing.

The termination and intermediate joints are required 遊雅堂 入金 エラーttings for connecting superconducting power cables. The termination is a terminal that is installed at the cable end to connect with electric equipment installed at room temperature. The intermediate joint connects superconducting power cables to each other and is necessary when laying cables over long distances. Since the superconducting power cable is cooled by liquid nitrogen and the conductor is exposed to high voltages, the joints must feature heat insulation for liquid nitrogen temperatures and room temperatures, as well as electric insulation for earth and high voltage.
