Bare Copper Winding Wire

Bare Conductor

Bare Copper Winding Wire

As the basic conductor of other winding wires, bare copper wire is defined as an oxygen-free copper rod that is made into various specifications of flat wire or round wire after a specific specification mold extrusion or drawing is made in accordance with customer requirements. This wire is then prepared for coating processes using paint, paper, fiber glass, or other insulating material covering insulation. The product can be used for life wire supplies or winding of transformers, generators, motors, reactors, and other electrical equipment.

    • The fundamental property of bare wire is its adaptability to the use environment. This adaptability is primarily demonstrated by its resistance to high and low temperatures, radiation, corona, pressure, oil, torsion, flame retardant, fire prevention, lightning protection, biological invasion, and other performance indicators following an insulation treatment.

    Advantages of continuous extrusion technology:Heg

    Using continuous extrusion to produce copper flat wire, the temperature of copper blank before the extrusion die can reach more than 600℃, the pressure can reach more than 1000MPa, and it is a three-way compressive stress. Under such high temperature and high pressure conditions, the original internal defects of the copper billet, such as pores, can be eliminated in the continuous extrusion process.

    Because the continuous extrusion of copper flat wire can directly extrude the copper wire wire into the finished product, the surface of the copper flat wire will not produce burrs and other surface defects, and the copper flat wire has good surface quality.

    Due to the use of a single billet, only a simple replacement of the mold can produce various specifications of copper flat wire products, and do not need to annealing, so the production cycle is very short, can achieve "same day delivery", without the need to stock and prepare various specifications of billets, greatly shorten the production cycle, reduce the occupation of funds, improve the material utilization rate and yield. It is especially suitable for the production of copper flat wire with many varieties and small batches.

    The mold material and structure can ensure that the product has a high dimensional accuracy, which can not only meet the requirements of national standards, but also ensure that the same batch of products have the same size.

    The whole production line adopts advanced computer control system, the production process can be automatically monitored and run, to achieve automatic production, reduce the labor intensity of the operator.
