Signalkabel

Multi-core cables 

• K22 (RATP), A-2Y2YV, A-2Y2YB2Y, A-2Y2YDB2Y
• Kupferne, vielpaarige Signal- und Steuerkabel sind hybride Energie-/Telekommunikationskabel, mit denen Niederspannung übertragen und Zwei-Wege-Telekommunikation ermöglicht wird.

Nexans hat für führende Eisenbahnbetreiber kundenspezifische Kabel mit elektromagnetischer Störfestigkeit (hoher Reduktionsfaktor) entwickelt. Diese sind insbesondere für Hochgeschwindigkeitsstrecken von Bedeutung. Zu den jüngsten Erfolgen zählen mehrere U-Bahn-Projekte wie die Projekte in Santiago (Chile), Neu-Delhi und Hanoi sowie in Reims (Frankreich) und Algiers.

Multi-quad cables

• Typically K23 (RATP), ZPAU & ZPFU (SNCF), A-2Y(L)2YV or AJ-2Y(L)2YDB2Y
• Copper multi-pair signalling cables are twisted pairs or quad cables providing low frequency and two-way telecommunications for field equipments.

For major railway operators, Nexans has developed customized EM-immunity (high-reduction factor) cables which are especially important for high-speed lines. Recent successes include several subway projects, like Santiago (Chile), New Delhi and Hanoi; and subway projects in Reims (France) and Algiers.

Axle counter cables 

• These cables connect trackside counting points which determine train presence, direction of travel, length, number of wagons and integrity.

Balise cables 

• Nexans advanced balise cables are flexible, resistant and have Electromagnetic Compatibility (EMC) for HF communications to eventually integrate a fully radio-based GSM-R traffic management system.

Recent projects include the Marmaray project (to link the European and Anatolian halves of Istanbul by an undersea earthquake-proof tunnel under the Bosphorus), and the New Delhi metro. 

DuoTrack® cable 

• Figure-8 duplex copper/fiber cable, which is securely clamped right on the tracks
• It is used to provide routing information with communications and control functions for regional railway lines, including ETCS capability.
• Fast and easy to install, it saves 30-40% of installation time
• DuoTrack® achieves overall ownership cost savings of over 50%.

In 2009, Nexans received a three-year framework contract from Deutsche Bahn for a DuoTrack® system of about 1,000 km. Nexans not only worked closely with DB, but also with system integrators to achieve a truly unified turnkey solution.
