Ga. firm buys American Insulated Wire

AMERICAN INSULATED WIRE’S headquarters in Mansfield.

MANSFIELD – A Georgia company has acquired American Insulated Wire Corp., an 86-year-old business that was based in Rhode Island until it moved its corporate headquarters to Massachusetts a few years ago. Financial terms were not disclosed.

Southwire Co. said it purchased all of American Insulated Wire’s assets, including the firm’s brands and its factories in Douglas, Ga., and Coffeyville, Kan., both of which produce building wire products for commercial and industrial customers and original equipment manufacturers.

Southwire CEO Stuart Thorn said American Insulated Wire’s “product diversity and strong manufacturing expertise make it a perfect fit for Southwire’s commitment to industry-leading service for our customers.”

American Insulated Wire was founded in 1924, according to corporate documents. It had been a subsidiary since 1936 of Melville, N.Y.-based Leviton Manufacturing Co. Inc., a manufacturer of electrical and electronic products.

For years, AIW was headquartered in Pawtucket – opening a new plant at the former home of Superior Telecom Inc. in 2000 – but moved to Mansfield sometime after 2005. A decade ago, the company employed about 700 workers at a manufacturing facility in South Attleboro, as well.

“American Insulated Wire … has been an integral part of Leviton,” Leviton President and CEO Donald J. Hendler said last month. “However, as we continue to shift our offering to more value-added systems and solutions, we no longer see AIW’s wire and cable products as strategic to the future direction of the Leviton Company.”
