Disadvantages of the magnesium-copper contact wire currently mainly used: medium strength and medium conductivity, low softening temperature, waste of electric energy.
The advantages of the CuCrZr contact wire: high strength and high conductivity, high softening temperature, safer, more reliable and stable than the magnesium-copper contact wire, and significant energy saving effect. The chromium-zirconium-copper contact wire can meet the safe, stable and low-cost operation of high-speed rail at 500km/h.
Innovations of CuCrZr contact wire:
1. Vacuum duplex melting
2. Vacuum continuous casting of large section bar billets
3. Using high-speed wire hot rolling technology
4. Quasi-constant temperature rolling and online solid solution technology
5. Large-size coil curling technology
6. Tandem cold rolling and giant drawing forming
7. Vacuum secondary aging
