Subway and Train
Copper plays a vital role in subway and train systems due to its excellent electrical conductivity, durability, corrosion resistance properties. Below are key applications:
1. Power Transmission and Electrical Systems
Rail Grounding Systems
- √ Copper cables and clamps are used to ground rails in electrified systems, ensuring safe current dissipation and preventing electrical hazards.
Power Cables
- √ Copper cables (e.g., mineral-insulated or fire-resistant types) transmit electricity to trains and infrastructure, offering reliability in high-temperature or fire-prone environments.
Overhead Catenary Systems
- √ Copper or copper-alloy wires are used in overhead lines to supply power to trains via pantographs.
2. Signaling and Communication
Signal Wiring
- √ Copper wires ensure precise transmission of signals for train control, track switching, and communication systems.
Connectors and Terminal
- √ Copper alloys are used in electrical connectors, relays, and terminals for their conductivity and resistance to oxidation.
3. Structural and Mechanical Parts
Heat Exchangers:
- √ Copper tubes in HVAC systems regulate temperature in train cabins and underground stations.
Bearings and Bushings
- √ Copper alloys are used in bearings and bushings for their wear resistance and low friction.
4. Signal Transmission and Communication Control.
- √ Waveguide-based transmission systems are integrated into subway networks to enable real-time communication between trains and control centers. This ensures precise train positioning, speed regulation, and collision avoidance. Plus, waveguide systems are critical for maintaining stable wireless communication in tunnels, where traditional radio signals weaken. A multi-mode waveguide tunnel channel model has been developed to simulate high-speed train (HST) wireless channels, ensuring continuous connectivity for onboard systems and passenger networks.
