XT650/600 Continuous extrusion machine for copper

High-speed railway contact line is the only important wire that directly delivers electricity to electric locomotive through sliding friction in the overhead contact line of electrified railway, and it is the key wire in the overhead contact line of electrified railway  At present, the design speed of high-speed railway is more than 300 km per hour, which requires high contact line  It not only has good electrical conductivity but also has high tensile strength, strong hardness and high temperat
