Nexans is participating in China's first high-temperature superconducting power cable project, led by Innopower Superconductor Cable Co.
Nexans is participating in China's first high-temperature superconducting (HTS) power cable project, led by Innopower Superconductor Cable Co.
The project is based at a power station in Kunming, the capital of Yunnan Province in southern China.
The 30m-long three-phase HTS cable, rated at 35kV and 2kA, will be installed in spring 2004 in the Yunnan Electric Power Group Co's power grid.
Nexans will supply both the electrical and the thermal insulations.
A Cryoflex vacuum-insulated flexible cryogenic envelope will provide the thermal insulation required to maintain the cable core at its operating temperature of about -200C.
Dr Ying Xin, General Manager of Innopower, commented : "We chose Nexans because it is a world leader in flexible cryogenic envelopes, in addition to its broad expertise in cable manufacturing.
We have a corporate agreement with Nexans to collaborate in developing HTS cable technology and we look forward to further joint projects in this field".
Jean-Maxime Saugrain, Nexans' Superconductor Activity Manager added: "Flexible cryogenic envelopes have been supplied by Nexans for more than 20 years and we have gained considerable experience through our participation in numerous projects involving cryogenic fluids.
This technology is now available for providing the thermal insulation of HTS cables".
