Railway Rolling Stock Cables

ZTT’s railway rolling stock cables are engineered to ensure safe and reliable operation of modern rail systems. Designed with low-smoke zero-halogen (LSZH) materials and enhanced fire-resistant performance, these cables help maintain circuit integrity under fire conditions while minimizing smoke and toxic emissions. Optimized for confined installation environments, they combine compact structure, flexibility, and mechanical durability, supporting high-speed trains, metros, and light rail systems.

Product Advantages

High Fire Safety: Manufactured with low-smoke zero-halogen (LSZH) materials, these cables ensure minimal smoke emission and no toxic halogen gases in case of fire, meeting EN 45545-2 requirements for passenger and driver safety.
Space and Weight Reduction: Thin-wall and ultra-thin-wall designs (EN 50306) significantly reduce cable diameter and mass, enabling dense wiring in modern high-speed trains and light rail vehicles.
Wide Voltage Range: From 300/500 V (EN 50306) up to 3.6/6 kV (EN 50382), the product portfolio covers control circuits, auxiliary systems, main power lines, and traction motor connections.
Excellent Thermal Performance: Silicone rubber insulated cables (EN 50382) withstand continuous operating temperatures up to 120°C or 150°C, ideal for engine compartments and braking resistor areas.
Robust Mechanical Protection: Standard-wall cables (EN 50264) offer high abrasion, oil, and fuel resistance, suitable for underfloor and exposed environments with heavy vibration.
Flexibility and Ease of Installation: Stranded tinned copper conductors and cross-linked polyolefin (XLPO) insulation provide excellent flexibility, simplifying routing in tight spaces and junction boxes.
Electromagnetic Compatibility (EMC): Multi-core screened versions (EN 50264-2, EN 50306-4) reduce crosstalk and external interference, ensuring reliable data and control signal transmission.
Long Service Life: Cross-linked insulation and sheathing materials deliver superior aging, ozone, and weather resistance, reducing maintenance and replacement costs over the vehicle lifetime.

Product Introduction

EN 50264: Covers standard-wall, low-smoke zero-halogen (LSZH) cables for railway rolling stock, rated at 0.6/1 kV and 1.8/3 kV, designed for main and auxiliary power circuits in underfloor and interior areas.
EN 50306: Specifies thin-wall and ultra-thin-wall LSZH cables rated at 300/500 V, offering lightweight and space-saving solutions for control, lighting, and data signal wiring inside driver cabs and passenger compartments.
EN 50382: Defines high-temperature, halogen-free silicone rubber insulated cables rated at 1.8/3 kV and 3.6/6 kV, used for traction motor connections and other hot-spot applications in railway vehicles.
WDZ: Stands for Low Smoke Zero Halogen (LSZH) characteristic, meaning cables with no halogens, low smoke emission, and flame retardancy, widely used in rolling stock and other public areas to ensure fire safety.

Application Scenarios

Rolling Stock Interior Systems: Wiring for passenger compartments, driver cabins, lighting, and onboard control systems.
Onboard Equipment and Control Systems: Connections for control cabinets, HVAC systems, and auxiliary equipment.
