These flexible perforated coaxial cables act like antennas in twisting or confined environments, like tunnels, where conventional antennas cannot operate. They are extremely important for ERTMS/ETCS radio-based technologies.
Nexans provided integral cabling for the 35-mile long Lötschberg railway tunnel in Switzerland, which will be the longest in Europe. Along with energy and optical fiber links, radiating cables will assure full GSM-R operability.
