Nexans railway cables for the speedy transfer of energy and data
InnoTrans - International trade fair for transportation engineering - hall 01.1, stand 248
Mönchengladbach, August 31, 2006 – At InnoTrans 2006, Nexans is exhibiting solu-tions for energy and data transfer in transportation engineering, including power cables for locomotives and railcars, sockets and connections, control, data bus and coaxial cables, cable harnesses and connecting cords as well as wrap wires for trans-formers and motors.
Two recent solutions deserve special attention, both representative of their areas of application: the RAILNET 100 communication cable for networks inside trains and the RHEYHALON (N)TMCGCHXOE energy cable for transferring energy between the power consumer and the transformer.
Nexans is turning the railway into an internet café
Rail travellers are spending more and more time on their computers. Railway opera-tors are extending these on-board communication possibilities. For example, Deutsche Bahn AG already has six ICEs in operation, providing passengers on a section of the track in the Rhein-Ruhr area with a wireless internet connection (WLAN). In just a few years, it has almost become part of everyday life to go online with Notebook on a wireless basis, in order to exchange e-mails, access the company server or surf the internet. For data transportation between the WLAN connection and a server inside the train, which serves as a data buffer and communication control station, cables such as the RAILNET 100 from Nexans are used. In addition, it is suitable for the transmission of videoconferences or video imports and other network applications.
The RAILNET 100 cable fulfils the same function as a network cable in an office set-ting, but also has special features for use on trains: it can withstand vibrations and is flame resistant. It is also halogen-free and does not give off any toxic substances in the event of a fire. This profile of features fulfils the current European Fire Protection Guidelines for railway traffic. In contrast to a conventional network cable, it is specified for a much broader range of temperatures (-40 °C to +85 °C). The thin walls of the data line have wire insulation and a coating made from meshed plastic. This meshing process increases the three-dimensional adhesion of the plastic molecules and thus, despite the small external diameter, ensures longevity even under strong mechanical stresses.
RHEYHALON (N)TMCGCHXOE: high-tech cable for power consumers
The range of Nexans energy cables complying with EN 50264 exhibited at the last InnoTrans has since been augmented. The innovations to be seen at this year’s trade fair include the RHEYHALON (N)TMCGCHXOE. It connects components such as power consumers and transformers and is designed for a system voltage of 26/45 kV (maxi-mum voltage 54 kV). All the standard voltage levels are thus covered. Its conductor consists of fine-strand tinned copper, the sheathing is resistant to both oil and diesel oil and is not sensitive to the influence of ozone or UV rays. Thanks to its newly devel-oped compact insulating material, the cable takes up little room and is comparatively light. It is available as piece goods or as a ready-for-assembly, preformed and electri-cally tested connecting cord with plug and cable end.
EUROBALISE : the new generation of signalling cables
Modern high-speed trains also demand infrastructure cables with different characteris-tics in terms of bandwidth, safety, electromagnetic immunity and resistance, while en-suring a real interoperability between systems from different countries, fitting for ex-ample the requirements of the new consolidated ERTMS/ETCS standards. Nexans EUROBALISE advanced balise cables are specifically adapted to evolving rail infra-structures. They are flexible, resistant and have electromagnetic immunity for HF communications for an escalating and eventually fully radio-based GSM-R traffic management system. EUROBALISE cables are also compliant with ever-demanding safety requirements, as they are halogen-free, flame retardant and assure low toxicity and minimal smoke. EUROBALISE cables make it possible to achieve continuity in the evolution of rail infrastructures to meet the challenge of interoperability and provide them with the headroom needed for full railway unification.
