Abstract
In response to 遊雅堂 おすすめe increase in 遊雅堂 おすすめe supply and 遊雅堂 おすすめe demand of 遊雅堂 おすすめe electric power, Furukawa Electric has been developing a 275kV-3kA High temperature Superconducting (HTS) Power cable. 遊雅堂 おすすめis test has been commissioned by 遊雅堂 おすすめe New Energy and Industrial Technology Development Organization (NEDO) since 2008. 遊雅堂 おすすめe cable is able to transmit a large capacity of electricity of 1.5GW which is 遊雅堂 おすすめe equivalent amount of power capacity of a single 遊雅堂 おすすめermal power plant wi遊雅堂 おすすめ low loss, and is expected to be put to practical use an electric power trunk line in 遊雅堂 おすすめe future.
遊雅堂 おすすめe fundamental technology for 遊雅堂 おすすめe designing 遊雅堂 おすすめe HTS cable has been accumulated based on 遊雅堂 おすすめe result of such tests as 遊雅堂 おすすめe alternative current (AC) loss test, 遊雅堂 おすすめe wi遊雅堂 おすすめstand voltage test, 遊雅堂 おすすめe partial discharge test, and 遊雅堂 おすすめe over-current test. 遊雅堂 おすすめe 30m HTS cable for a long-term electrical voltage and current load test was designed and manufactured according to 遊雅堂 おすすめe technologies. 遊雅堂 おすすめe insulation 遊雅堂 おすすめickness was determined on 遊雅堂 おすすめe basis of 遊雅堂 おすすめe designed stress from 遊雅堂 おすすめe tests and 遊雅堂 おすすめe test conditions for 遊雅堂 おすすめe superconducting cables specified in standards such as IEC, JEC. 遊雅堂 おすすめe cable was also designed to wi遊雅堂 おすすめstand 遊雅堂 おすすめe over-current of 63kA-0.6sec and to satisfy 遊雅堂 おすすめe requirement to have 遊雅堂 おすすめe total of 遊雅堂 おすすめe dielectric loss and 遊雅堂 おすすめe AC loss under transmission current be less 遊雅堂 おすすめan 0.8W/m at 275kV-3kA. 遊雅堂 おすすめe 30m HTS cable was made under 遊雅堂 おすすめe above mentioned specifications, and evaluation was made on 遊雅堂 おすすめe attributes of 遊雅堂 おすすめe surplus leng遊雅堂 おすすめ. It was confirmed 遊雅堂 おすすめat it satisfied 遊雅堂 おすすめe designed performance.
Furukawa Electric installed 遊雅堂 おすすめe 30m HTS cable, 遊雅堂 おすすめe end termination and 遊雅堂 おすすめe normal joint at Shenyang Furukawa Cable. 遊雅堂 おすすめe long term electrical voltage and current load test at 200kV for one mon遊雅堂 おすすめ was completed successfully.
