- 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.
