3M says that Georgia Power, a subsidiary of Southern Co., has chosen the company's lightweight, low-sag ACCR overhead conductor to double transmission capacity on a set of lines that cross extensive wetlands near Savannah.

The upgrade is on a 16.7-mile line linking the Kraft generating plant in Savannah with the McIntosh plant north of the city. According to 3M, the upgrade reduces the need for larger towers or a wider right of way, as well as resolves potential capacity issues by approximately doubling the 230 kV double circuits’ line capacity, replacing a conventional steel core conductor with a 3M ACCR 1622 kcmil conductor.

"3M ACCR enabled us to use mostly existing towers and to re-conductor with minimal disturbance to the land and no service interruption,” says Southern Co.’s Bob Beck.
