Yantai Wanlong Vacuum Metallurgy Co., Ltd. produces high-speed railway copper-chromium-zirconium contact wires, catenary wires, and dropper products

by utilizing advanced preparation technologies such as vacuum casting, high- speed hot continuous rolling, online solution treatment, and cold continuous

rolling. These products feature high strength, excellent electrical conductivity, high softening temperature, and good wear and corrosion resistance, are less

prone to arcing and sparking, and are more suitable for sections with harsh operating conditions such as high-speed, heavy-haul, strong wind, submarine

tunnels, steep slopes, and high-density traffic.
