Bare Earth Wire

 

Bare copper earth wire conductors are composed of pure copper wires, which are carefully drawn from flexible and shiny pure copper rods. These bare copper wires boast a metallic luster and a smooth appearance, making them translucent and highly conductive. They have excellent transmission capabilities and are known for their strength, conductivity, and flexibility, which makes them the ideal choice for grounding wire applications. When it comes to high performance conductors, bare copper is undoubtedly the top choice.

A ground wire, often called a bare copper wire, is a widely used type of wire that is directly connected or linked to ground through another ground conductor.

The most essential and straightforward wire and cable product available is bare copper wire. It finds extensive utilization in our daily lives as well as in various production processes. Notably, a section of bare copper wire serves as the grounding wire for equipment used in both manufacturing and everyday activities. Consequently, this versatile wire type is in high demand due to its fundamental nature and widespread applications.

The safety return line, also known as the grounding wire, is the wire that is directly connected to the earth. It is designed to transfer any sudden and abnormal high voltage to the earth, preventing any danger or damage. The grounding wire is like a lifeline during unstable voltage situations, making it an essential component in any electrical system.

 

 

The grounding wire made of bare copper possesses excellent electrical conductivity, in addition to its remarkable physical and mechanical characteristics like its impressive strength.

The primary purpose of the ground wire is to provide electrical protection. When there is a leakage or inductive charge in your electrical equipment, the ground wire swiftly directs the current to the ground, effectively discharging the equipment shell. By doing so, it guarantees the safety of both personnel and the equipment itself. The paramount characteristic of the bare copper grounding wire lies in its remarkable conductivity, allowing for the rapid flow of current into the ground. This ensures the utmost safety for individuals, equipment, and buildings. Hence, the grounding wire's role is crucial in safeguarding against potential hazards associated with electrical systems.

 

 

Bare copper grounding wire is an un-insulated wire with a smooth surface that finds ubiquitous applications in the electrical power industry, telecommunications, transportation engineering, transformer, and motor manufacturing.

 

 

 

The excellent electrical conductivity and robust heat transfer capability of the copper grounding wire make it an ideal choice for grounding purposes. This wire is specially designed with soft material, ensuring flexibility and ease of installation. Its remarkable electrical conductivity allows effective flow of electrical current, while the strong heat transfer capability facilitates efficient dissipation of heat. Overall, the copper grounding wire's softness, electrical conductivity, and heat transfer capability make it a reliable and efficient option for grounding applications.

 

 

Bare copper wire must meet 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", JIS C 3102 "Annealed copper wire for electrical purposes"

 

 

After the bare copper grounding 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: How is a bare copper earth wire installed?

-A: The installation of a bare copper earth wire typically involves connecting one end to the grounding electrode system, such as a grounding rod or a metal water pipe, and the other end to the electrical system's grounding bus or terminal.

 

Q: Can a bare copper earth wire be used for other applications?

A: Yes, apart from electrical grounding, bare copper earth wire can also be used in various other applications. It is commonly used in lightning protection systems, telecommunications grounding, and in some cases, as a component in overhead power transmission lines.
