About Southwire

Southwire leads the industry with innovative products that can help simplify installation, saving you time and money. Southwire has the right wire and cable solution for any commercial, residential, industrial or utility application.


Southwire delivers power to millions of people around the world. Our utility cable and building wire carry electricity to wherever it is needed. One in three new homes built in the United States contains wire made by Southwire.

Our corporate structure centers around four distinct manufacturing segments—Energy, Electrical, OEM (Original Equipment Manufacturing) and SCR® (Southwire Continuous Rod). Each focuses on a specific group of products and customers.

Our Energy division sells a full line of low-, medium- and high-voltage cable products that move power from the generation source to buildings and homes. Customers include investor-owned utilities, rural electric cooperatives, municipalities, contractors and utility distributors.

Our Electrical division products distribute power inside homes and buildings. Whether it's Romex® brand building wire, copper or aluminum MC, copper AC or flexible, metallic or liquid-tight conduit, 600-volt or 24-kilovolt wire, our Electrical division's products move power exactly where it is needed.

Our OEM division sells wire and rod to customers who manufacture such products as automobile wiring harnesses, insect screening, transformers, electric motors, HVAC equipment, appliances and industrial equipment.

Our SCR® Technologies division has been the technological leader in continuous cast copper and aluminum rod manufacturing since the 1960s. More than half of the continuous-casting copper rod capacity in the world uses our technology—which means most of the world's copper wire passes through technology provided by Southwire.
