GB/T 20509-2006
AbolishedCopper and copper alloys drawing stock for the contacting materials of electric locomotives
电力机车接触材料用铜及铜合金线坯
Application Summary AI generated
This standard specifies the technical requirements, test methods, inspection rules, and packaging for copper and copper alloy wire rods used as raw material for manufacturing contact wires in electric locomotive overhead catenary systems. It is applied in the railway electrification industry to ensure that the drawing stock meets the necessary conductivity, strength, and wear resistance for reliable current collection at high speeds. The standard governs the production and quality control of these materials before they are drawn into final contact wires for use in electrified railway networks.
