Copenhagen AMK station 2001
Worlds first
Worlds first high temperature superconducting cable in the electric power network has been manufactured by NKT Cables and with success installed in the electric power network at Copenhagen Energy. The cable is a 30-meter long 30 kV demonstration cable supplying a part of Copenhagen, the capital of Denmark. The cable has a power rating of 2,000 A, and the cable can supply approximately 50,000 households as well as offices and industry on the island of Amager - the southen part of the city.

Project goal
The goal of the project is to demonstrate a superconducting cable system in the electric power network under realistic conditions and to collect experience regarding installation and operation of a superconducting cable system.
The project shall demonstrate that a complete superconducting cable system including cable, termination, cooling etc. can work satisfactorily in a realistic environment with realistic environment affects. This includes variation of load, possibilities of overcurrents and short-circuit currents, thermal and mechanical load as well as operation by the utility staff.
Project schedule
The project shall demonstrate the feasibility of a superconducting cable system in the electric power utility and thereby prepare the way for commercial application of superconducting cables in the electric utility.
The three single-phase cables are manufactured by NKT Cables and delivered to test facilities at Technical University of Denmark in December 2000 where tests have been carried out. The cables have been tested electrically and thermally with great success. All three cable conductors passed the test with no problems.
During January and February 2001 the cables are delivered to the site at Copenhagen Energy and installed. Installation of cables, cooling equipment, breakers etc. is done during March 2001 and the cables are powered for the first time in May 2001.
