Stranded Soft Drawn Bare Copper Naked Copper Cable

Stranded soft drawn bare copper, also known as naked copper conductor, is a high-conductivity electrical cable composed of multiple strands of soft annealed copper wire without any insulation or jacket. It is commonly used for grounding, bonding, and power distribution in electrical systems where flexibility and high performance are essential. Available in a wide range of sizes and configurations, this conductor offers excellent current-carrying capacity and ease of installation.

Application

Stranded soft drawn bare copper is widely used in overhead transmission, distribution networks, and grounding systems. Thanks to its excellent electrical conductivity and flexibility, it is also ideal for use in uninsulated hook-ups, jumpers, bonding conductors, and grounding applications in electrical construction.
