Double spooler

Developing a world- beating superconductor

Rosendahl’s new semi-automatic double spooler, RODS1250 H, is designed for high speed insulation processes. The RODS1250 H has a highly rigid machine frame with a product clamp for easy thread-up, and includes a height- adjustable traverse pulley unit for better winding quality. The RODS1250 H double spooler is set up for flat cables and for products of up to 15mm in diameter, operating at speeds of up to 1,500m per minute with reels of up to 2,500kg in weight. The spooler can change between two spools at full production speed, and an automatic reel change cycle is said to take only a few minutes. The Rosendahl double spooler is made for semi-automat- ic cable production

NKT is working in conjunction with six partners

NKT and six partners have started work on the Superlink project, the prototype development of a superconductor specially designed for the city of Munich, Germany. When the Superlink technology has been developed, and the project tendered, it is expected to become a 12km underground power link - the longest superconducting power cable in the world. Anders Jensen, chief technology officer at NKT, commented: “We are proud to take part in the early stages of the development of SuperLink, where Stadtwerke München and Stadtwerke München Infrastruktur are taking a significant step to leverage superconducting power cables. It is important to continue to develop solutions to support the transition to renewable energy and the ambitions of the German Energiewende. “[At] NKT we see superconducting power cables as a part of the future, to ensure optimized access to clean energy in larger cities such as Munich.” The superconducting cable will be cooled to -200ºC with nitrogen in a closed circuit; a cooling system with redundant back-up coolers will be an integral part of the system.
