Production process of flexible copper stranded wire

Soft copper stranded wire is suitable for flexible connecting wires for electrical equipment, electronic appliances or component wiring, or conductor cores for flexible structural cables used in these occasions. The DC resistivity (20°C) is not greater than 0.0182Ω.mm^2/m, and the main product standards are in accordance with GB∕T12970.2-2009 Electrical Soft Copper Stranded Wire Part 2: Soft Copper Stranded Wire.
The development department of Xingma Copper Industry received the new product information from the sales department. The specific production process should be based on the specific equipment conditions of the factory and in accordance with the requirements of the national standard GB∕T 12970.2-2009 "Electrical Soft Copper Stranded Wire Part 2: Soft Copper Stranded Wire" , Compile the corresponding production process documents and technical specifications.
Employees according to the specific process documents weaving
Soft copper stranded wire process flow: copper rod → copper rod inspection (according to GB/T3952-2008 copper wire blank for electrical use) → wire drawing (large drawing machine) → medium and small drawing → stranding (tube stranding machine or wire binding machine) → Conductor stranding (tank annealing) → Finished product inspection (according to the standard GB12970.2-2009) → Packaging → Storage
Basic process flow of tinned annealed copper stranded wire: Copper rod → Copper rod inspection (according to GB/T3952-2008 "Copper Wire Blank for Electrical Engineering") → wire drawing (large drawing machine) → tinning (electrolytic tinning machine) → middle, Small drawing (continuous annealing) → hot-dip tinning (this process is when there is no electrolytic tinning machine) → stranding (tube stranding machine or wire beaming machine) → conductor stranding (tube stranding machine, cage stranding machine, requiring back twisting) → Finished product inspection (according to the standard GB12970.2-2009) → packaging → storage.
