Abstract
In the Russia's Scientific R&D Cable Institute (VNIIKP) the 5 m cable core sample was produced and tested as a first prototype in preparation for the production of a proposed 30 m 3-phase cable with a design rating of 2 kArms and planned operating voltage 20 kV. The work is done in the framework of the FGC-VNIIKP Project on R&D of HTS power cables, funded by Russia's Federal Grid Company's (FGC) United Energy Systems. Before starting the full length cable production the extensive technology studies have been performed. These works permitted to develop the proper former and cabling technologies for the long HTS power cables. To verify the calculations and designing principles the first prototype was heavily instrumented to measure current distribution among layers, voltage-current characteristics and other parameters. The details of the design of the cable model and test results are presented and discussed.
