SPECIFICATIONS
| Segment | Application | Models | Key Features |
|---|---|---|---|
| Segment 1 | Conventional-speed railways, urban rail transit, and heavy-haul railways with design speeds below 160 km/h | CTA120, CTA150, Tinned CTA120, Flat-bottom Tinned CTA150 | Excellent electrical conductivity and high current-carrying capacity. Reduces transmission losses and delivers reliable power supply performance. Tinned variants provide superior corrosion resistance, while flat-bottom designs improve pantograph contact stability and reduce wear. |
| Segment 2 | Electrified railways, passenger dedicated lines, and urban rail transit with design speeds of 200–250 km/h | CTA(H)120, CTA(H)150 | High mechanical strength and excellent conductivity. Suitable for railways with large gradients, complex terrain, and demanding operating conditions requiring enhanced mechanical performance. |
