Bare wires encompass the fundamental classification of wire and cable products. These wires serve various purposes, including being utilized as conductive wires and cables. Moreover, they are commonly used as components in equipment such as motors, electrical appliances, and transformers. Furthermore, bare wires find direct applications in the transmission of electric energy and information within departments like electric power, communication, and transportation. To effectively perform these functions, it is crucial for bare wires to possess excellent electrical conductivity, as well as possess reliable physical and mechanical properties.

Wires that are bare do not have any protective covering or insulation, and lack a sheath structure as well.

 

 

The physical and mechanical properties of the bare copper wire are excellent, in addition to its impressive electrical conductivity. This makes it a versatile material for a wide range of applications.

The purpose of the bare wire is to direct any unusual electric current into the earth in case of an emergency, but under normal conditions, there should be no current flowing through the ground wire, which is intended to keep it safe. Proper grounding is a highly effective method of preventing any incidents of electric shock and overload, which could otherwise pose significant hazards.

The safety regulations require that all types of grounding wires, such as lightning protection grounding, anti-static grounding, and protective grounding, should be in the form of bare wires. It is important to adhere to this uniform standard across various applications to ensure safety. This means that the grounding wires must not have any insulation or protective covering, making them easily identifiable and distinguishable. Whether it is for protection against lightning strikes, preventing static electricity buildup, or ensuring a secure grounding connection, the use of bare wires is a fundamental requirement. By following these guidelines, we can maintain a consistent and reliable approach to grounding in different scenarios.

 

 

A bare single wire refers to a wire that has a surface without any insulation layer. This type of wire finds its primary application in various industries such as electric power manufacturing, transportation, telecommunication engineering, as well as in the production of motors and transformers.

 

 

 

The bare wire possesses remarkable electrical conductivity and efficient heat transfer capacity due to its soft material composition. Additionally, it retains its superior characteristics without any insulation covering.

Copper wire is widely recognized as an optimal selection for tasks that demand superior electrical conductivity because copper boasts exceptional conduction abilities. Thus, it is considered one of the most efficient materials for transmitting electricity.

Copper possesses inherent resistance to corrosion, a valuable characteristic that safeguards the wire's conductivity and safeguards against deterioration as time passes. Under certain conditions, however, it is possible for copper to exhibit an oxide layer or develop a patina when exposed to specific environments.

 

 

To comply with the necessary standards and ensure safety and efficiency, bare copper wire should adhere to various regulations such as GB/T 3953 "Electrical Round Copper Wire," GB/T 4909 "Test Method for Bare Wire," ASTM B1 "Standard for Hard Drawn Copper Wire," ASTM B3 "Standard for Soft Round or Annealed Copper Wire," and JIS C 3102 "Annealed copper wire for electrical purposes." These guidelines guarantee that the copper wire used in electrical applications meets the required specifications and quality standards. Adhering to such regulations not only ensures the reliability of the wire but also promotes uniformity and compatibility across different electrical systems. So, when it comes to bare copper wire, observance of these standards is of utmost importance.

 

 

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.
