Spezial-Mittelspannungskabelfuer den Einsatzals Langstatorwicklung im Fahrweg des Transrapid Shanghai

摘要

The Shanghai Transrapid project is the first real commercial application of the TRANSRAPID high speed MAGLEV technology. Over a distance of 30 km, the line connects Shanghai's Pudong International Airport with the Long Young Road Station of downtown Shanghai. Nexans' contribution to the Shanghai project was the long stator winding motor system, comprising the manufacture of the long stator winding cable, supervision of laying and installation work for the three-phase long stator winding, transport and on site logistics in terms of packing, shipment and assignment of the cables to the laying vehicles and motor sections and system acceptance tests after laying and installation of the cable. System solutions designed and realized with a focus on the following developments can be listed as follows: development of the cable design based on appropriate tests and extensive electrical and mechanical research, consideration of the specific laying conditions to be met using a fully automated robot laying technique, development of special production techniques to meet the specific requirements for cabling system and the laying technology, improvement of testing procedures to assess and guarantee system-relevant characteristics, particularly with regard to the long-term behavior, the use of jointing sleeve technologies with special regard to a long service life and assurance of all quality characteristics for the laid and installed long stator winding motor system. Nexans is able to provide details about a special cable solution, using high quality rubber compounds for conductor insulation and conductive outer sheating with gliding coating for the long stator winding cable, and to report that the high demands and specifications of the whole system were fulfilled.
