Introduction

Copper and copper alloy contact wires for electric traction are key material components for railways, urban transportation, industrial and mining and lifting systems. In order to improve this The technical applicability of the document is adopted in the form of technical consultation, industry research, experimental verification, etc. This revision mainly modifies and adds the copper-silver alloy Model specifications of gold contact wire, copper-tin alloy contact wire, copper-magnesium alloy contact wire, copper-chromium-zirconium alloy contact wire and flat bottom double groove contact wire and technical requirements, the current carrying capacity value and wear performance test method have been added to reflect the current copper and copper alloy contact wire technology for electric traction in my country Development and manufacturing levels to meet the above application scenarios, especially the application needs of high-speed electrified railways. GB/T 12971 "Contact Wires for Electric Traction" is intended to consist of two parts. ---Part 1.Copper and copper alloy contact wires. The purpose is to conduct technical requirements and test methods for copper and copper alloy contact wires. Regulation. ---Part 2.Steel-aluminum composite contact wire. The purpose is to stipulate the technical requirements and test methods for steel-aluminum composite contact wires. Contact wire for electric traction Part 1.Copper and copper alloy contact wires
