Annealed Bare Copper

Annealed bare copper wire refers to the bare copper wire that has been annealed and softened. The annealed bare copper wire has good flexibility and strong plastic deformation.

The purpose of annealing the annealed copper wire is to process the drawn copper wire in the state of "cold work hardening" to obtain the required electrical and mechanical properties. In this process, the internal stress of the copper wire is greatly reduced. , the distorted state of the lattice is eliminated, and a more stable energy state, that is, a lower energy state, is reconstituted. Unannealed copper wire has high hardness, is not easy to be oxidized and durable.

Annealed bare copper wire is a copper wire drawn from pure copper rods and annealed and softened. The material is single, and the inside and outside are copper metal.

Annealing bare copper wire is currently mainly used for furnace tube heating annealing and continuous pulling and continuous annealing for positive and negative electrode current annealing.

Annealed bare copper wire has good electrical conductivity and physical and mechanical properties. Bare copper wires have only conductors without other coverings such as insulation and sheath structure.

Q: What are the advantages of using bare copper wire?

Some advantages of using bare copper wire for grounding include its excellent electrical conductivity, corrosion resistance, and durability. Copper is one of the most effective conductors of electricity, allowing for efficient dissipation of electrical current into the ground. It also resists corrosion, which ensures a long-lasting and reliable grounding system.

Bare copper wire can be processed and derived into a variety of cables, which are widely used in cables, ultra-high voltage cables, communication cables, marine cables, automotive wires, photovoltaics, electronics, electromechanical and other fields.

In terms of physical properties, the bare copper wire is soft, has excellent electrical conductivity and strong heat transfer capability.

Bare copper wires must be produced and inspected according to the standards of GB/T 3953 "Electrical Round Copper Wire" and GB/T 4909 "Test Methods for Bare Wires".

After the bare copper wire is produced, it must be packaged, stored, handled and transported in strict accordance with customer and industry standards to ensure that the product is free from moisture and damage.
