Bare Copper

Cerrowire bare copper conductor wire is engineered for a wide range of essential electrical applications where durability, conductivity, and compliance are critical. This high-quality uninsulated copper wire is frequently used in overhead transmission lines and electrical distribution systems, providing reliable performance for utilities and large-scale infrastructure projects. Its excellent conductivity makes it the preferred choice for long-distance power transmission, where efficiency and minimal energy loss are essential.

In addition to transmission and distribution, bare copper wire is widely recognized as the industry standard for grounding applications. It is commonly installed as a grounding electrode conductor, bonding conductor, or grounding wire in both commercial and industrial electrical systems. Contractors and engineers rely on bare copper’s corrosion resistance, strength, and compliance with ASTM standards to ensure safe fault current pathways and effective lightning protection.

This versatile electrical conductor is also suitable for use in switchyards, substations, building foundations, and renewable energy projects where a dependable bare copper grounding system is required. Because it meets ASTM B3, B8, and B787 specifications and is RoHS compliant, Cerrowire bare copper conductors deliver trusted performance across diverse industries. Whether supporting utility-scale power distribution, commercial construction, or residential grounding systems, this product provides a proven solution that meets the stringent requirements of modern electrical installations.
