A 75m 10.5kV/1.5kA three‐phase AC high‐temperature superconducting (HTS) power cable was installed in a live power grid in China in January of 2005. A liquid nitrogen decompression (LND) cooling system was adopted for the 75m cable facility for two reasons: one is that the LND method is simple and reliable; the other reason is that we have successfully used this method with a 10 m cable prototype since 2003. The 75m HTS power cable facility with LND cooling was commissioned at the end of 2004. By August 21, 2005, the total running time of the cable in the live power grid was more than 4000 hours. In this paper we will discuss the design and running data of the cryogenic system and present some analytical results.
