Southwire is the leading manufacturer of wire and cable used to transmit electricity across North America.

Southwire Team

From humble beginnings, we grew to fulfill customer needs.


Our founder Roy Richards simply wanted to erect poles and string wire so his grandmother could read under electric light. That same spirit is how we’ve continued to grow into a global supplier of wire and cable, and the number one supplier of wire for utilities in the U.S. But we’ve never forgotten where we came from: we’re still private, still family-owned and still based right down the road in Carrollton, Georgia.


We manufacture half of the cable used in the transmission and distribution of electricity across America, and one out of every three homes contains our electrical wiring. More than half of the copper rod made around the world is produced with Southwire Continuous Rod (SCR®) technology – the highest quality, lowest cost product available.


With integrated R&D, production, sales, and logistics our complete approach allows us to be a single source for every wire and cable required to build or upgrade a substation. It also means your needs and questions influence innovations like Proof Positive® Copper.


Our engineers speak your language. You can rely on Southwire to help you anticipate and forecast, answer your questions and be where you need us – whether that’s on the other end of a call or next to you on site.


Wire is the starting point. Every challenge. Every day. The people of Southwire bring the innovation, expertise, and responsiveness you need for a successful substation project.
