Copper-Silver Alloy Series Contact Wire
The Copper-Silver (CuAg) Alloy Contact Wire Series is designed for electrified railways, urban rail transit, heavy-haul railways, and passenger dedicated lines requiring high electrical conductivity and reliable power transmission. With excellent current-carrying capacity, low transmission losses, and specialized tinned and high-performance variants, the series provides durable solutions for conventional, corrosive, and demanding operating environments.

SPECIFICATIONS
| Segment | Application | Models | Key Features |
|---|---|---|---|
| Segment 1 | Electric railway sector, especially conventional-speed railways, urban rail transit, and heavy-haul railways with a design speed below 160 km/h | Standard: CTA120, CTA150 Tinned: CTA120, Flat-bottom Tinned CTA150 | High electrical conductivity and current-carrying capacity, reducing transmission losses. Higher conductivity than comparable copper-magnesium and copper-tin contact wires. Tinned versions provide enhanced corrosion resistance for humid, coastal, and industrial environments. Flat-bottom tinned contact wires improve pantograph contact stability, reduce arcing, and minimize wear. |
| Segment 2 | Electric railway sector: electrified railways, passenger dedicated lines, and urban rail transit with a design speed of 200–250 km/h | CTA(H)120, CTA(H)150 | High mechanical stress resistance combined with excellent electrical conductivity. Suitable for large-gradient routes, complex terrain, and plateau railways requiring reliable power transmission and strong mechanical performance. |
