Application
Bare copper ground wire is mainly used for grounding purposes and complies with the relevant requirements of the National Electrical Code (NEC). Soft-drawn solid or stranded copper conductors are widely used for circuit grounding connections and grounding of mechanical equipment or electrical equipment. Hard-drawn copper conductors are commonly used in overhead transmission and distribution lines as circuit grounding connections and mechanical equipment grounding applications. Bare copper conductors are widely used in various grounding systems due to their excellent electrical conductivity and corrosion resistance to ensure the safety and stability of electrical systems.

Feature

Bare copper grounding wire uses soft bare copper conductor, which can be solid or Class A or Class B stranded, and meets ASTM B-3 and B-8 standards. This grounding wire is particularly suitable for grounding electrical systems that require high conductivity and flexibility, ensuring stable grounding performance and reducing the risk of electrical failures. Bare copper grounding wire can also be widely used in many other fields due to its excellent conductivity and durability to meet different electrical installation needs.
Certification
Bare copper ground wires are certified by UL (Underwriters Laboratories) and CUL (Canadian Underwriters Laboratories) to meet strict safety standards. Bare copper ground wires that pass these certifications ensure a reliable ground connection in electrical systems and meet electrical installation regulations in the United States and Canada. UL and CUL certifications indicate that the product has been rigorously tested and can be used safely in a variety of environments. Bare copper ground wires that pass these certifications provide users with protection to ensure the safe operation of electrical equipment and effectively prevent potential risks caused by electrical failures.
