Comprehensive cable system for metro, high-speed rail, and light rail — from 25kV traction power to station lighting, signaling, and tunnel emergency systems.
Rail transit cables operate in uniquely harsh environments: high-voltage traction fields, tunnel vibration, chemical exposure, and the absolute requirement that life-safety systems never fail.
Tunnel fires are catastrophic. LSZH cables prevent toxic fume generation that would trap passengers. EN 45545-2 compliance is mandatory for all tunnel installations.
25kV traction systems generate intense electromagnetic fields. Signaling and communication cables must be shielded to IEC 62236 to prevent interference with safety systems.
Rail-mounted cables experience continuous vibration. Flexible cables with vibration-resistant terminations prevent fatigue failures that could disable traction or signaling.
Outdoor rail cables must operate from -40°C to +90°C. Tunnel cables face high humidity and chemical exposure from cleaning agents and brake dust.
Fire-resistant cables for emergency lighting, evacuation systems, and communication must maintain operation for 90+ minutes during tunnel fires per EN 50200.
Rail transit power systems span from the national grid through traction substations to the overhead contact system, while station and tunnel systems require separate dedicated cable networks.
Rail transit requires cables across five distinct systems — traction, station power, signaling, communication, and emergency — each with unique performance requirements.
High-voltage AT feeder cables for 25kV traction power supply. XLPE insulation with aluminum or copper conductors, designed for 40-year service life in outdoor and tunnel environments.
Low Smoke Zero Halogen power cables for all station power distribution. Mandatory for underground stations and tunnels where toxic fumes would endanger evacuating passengers.
Shielded signaling cables immune to 25kV traction EMI. Ensures reliable ATP/ATC signal transmission that is critical for train safety and headway management.
Fire-resistant cables for emergency lighting, PA systems, and evacuation guidance. Maintains circuit integrity for 90+ minutes at 830°C, ensuring passenger evacuation.
Highly flexible cables for train-to-platform connections and rolling stock internal wiring. Designed to withstand millions of flex cycles without fatigue failure.
Specialized cables for DC traction return current and stray current drainage. Prevents electrolytic corrosion of underground infrastructure caused by stray DC currents.

| System | Recommended Cable | Key Standard | Critical Requirement |
|---|---|---|---|
| 25kV Traction Feeder | AT Feeder XLPE Cable | IEC 60840 | 25kV rated, 40-year outdoor/tunnel service life |
| Station Power Distribution | LSZH Power Cable | EN 45545-2 | HL3 fire hazard level for underground stations |
| ATP/ATC Signaling | EMC Shielded Signal Cable | IEC 62236 | Immune to 25kV traction EMI interference |
| Emergency Lighting/PA | Fire-Resistant LSZH | EN 50200 | 90-minute circuit integrity at 830°C |
| Rolling Stock Connections | Flexible Rail Cable | EN 50264 | Vibration-resistant, millions of flex cycles |
Non-LSZH cables in tunnels release toxic fumes that kill evacuating passengers before flames reach them. EN 45545-2 compliance is non-negotiable for tunnel installations.
Unshielded signaling cables in 25kV traction fields cause ATP/ATC failures. Signal failures can result in train collisions — the most catastrophic rail accident type.
Uncontrolled DC stray currents corrode underground pipes, foundations, and cable sheaths. Proper return current cables prevent millions in infrastructure damage.
Standard cables fail rapidly under rail vibration. Flexible rail-grade cables with vibration-resistant terminations prevent traction or signaling outages.
Our rail transit specialists provide EN 45545-2 and IEC 62236 compliant cable solutions for metro, high-speed rail, and light rail projects worldwide.
