Why use bare copper wire for grounding

In electrical engineering, the grounding system is one of the most important safety facilities. For grounding systems, choosing the appropriate conductor material is one of the most critical decisions. Why are bare copper conductors often used in grounding systems? Here are some important reasons:

 

 

First, bare copper wire has good electrical conductivity properties. Copper is an excellent conductive material with low resistance and high conductivity. It can effectively conduct ground current and ensure the normal operation of the grounding system.

 

Secondly, bare copper wires have good corrosion resistance. In outdoor or humid environments, metal wires are susceptible to oxidation and corrosion, which affects their conductive performance and service life. The bare copper wire not only does not contain an insulating layer on the surface, but also has good corrosion resistance and can be used for a long time in harsh environments without being affected.

 

Third, bare copper conductors are easy to install and maintain. Bare copper conductors do not require stripping of insulation, making installation easier and faster. Additionally, bare copper conductors require no special maintenance and can usually be kept in good working order with just regular inspection and cleaning.

 

Finally, bare copper wire is relatively low cost. Compared with other metal wires, the production and purchase costs of bare copper wires are relatively low, enabling economical construction of grounding systems while ensuring quality.

 

To sum up, bare copper wire has become a commonly used wire material in grounding systems due to its excellent electrical conductivity, corrosion resistance, easy installation and maintenance, and economical benefits. In electrical engineering, the correct selection and use of bare copper wires can effectively ensure the safe and reliable operation of the grounding system and ensure the safety of electrical equipment and personnel.
