Copper has good formability, and copper rods can be easily made into relatively thin copper wires without any intermediate annealing process. Bare copper wire is continuously drawn from copper rods. It has smooth surface, soft texture and excellent electrical conductivity.

Because of its good electrical and thermal conductivity, copper has become the first choice and main material in the fields of electronics and power industries and other fields that require copper. In order to meet the required performance standards, almost all high-purity copper is generally used in production.

The softness of copper is affected by the annealing of copper during processing. The annealing of copper is a very complex property. This property is composed of a series of other properties, which in turn vary with deformation, thermal history, metal purity and oxygen. changes with the amount of ingredients. Annealability is not simply related to some possible parameters, such as atomic weight or valence of solute, but is also complicated by thermodynamic interactions between multiple substances.

Bare copper wire is the most basic category of wire and cable products. Some products of bare copper wire can be used as conductive wires of wires and cables; another part of products are used as components in motors, electrical appliances, transformers and other equipment.

Bare copper wires can also be processed into various shapes according to needs, such as flat wires, round wires and various types of wires, etc., and can also be combined into various stranded wires and multi-stranded wires by combining multiple bare copper wires.

 

 

Bare copper wire has good electrical conductivity and physical and mechanical properties.

 

 

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.

 

 

Q: What is exposed copper wire?

A: Exposed copper wire refers to copper wire that is not covered or insulated with any protective coating. It means that the bare copper conductor is visible and accessible.

 

Q: Is exposed copper wire safe?

A: Exposed copper wire can be safe or unsafe depending on the context and application. Copper itself is a good conductor of electricity, but without insulation, it can pose risks of electrical shock, short circuits, or contact with other conductive materials. Proper precautions should be taken to ensure the safety of individuals and equipment when dealing with exposed copper wire.
