SPECIFICATIONS
| Segment | Application | Models | Key Features |
|---|---|---|---|
| Segment 1 | Electric railway sector, especially high-speed railways and passenger dedicated lines with design speeds of 300–350 km/h | CTMM120, CTMM150, CTMH120, CTMH150 | High strength, good toughness, excellent wear resistance, corrosion resistance, and superior temperature rise resistance. Compared with copper-silver and copper-tin contact wires of the same specification, these products provide higher tensile strength. Suitable for electrified railways, urban rail transit systems, passenger dedicated lines, and capacity expansion or reconstruction projects in conventional operating environments. Widely applied in major projects including the South Yangtze River Intercity Railway, Yancheng–Nantong Railway, Chengdu–Chongqing Passenger Dedicated Line, Chizhou–Huangshan High-speed Railway, Beijing–Shenyang Passenger Dedicated Line, and Beijing–Guangzhou High-speed Railway. |
