ABB builds extrusion tower at high-voltage transmission cable plant

Huntersville, N.C., August 12, 2011 — ABB reached a construction milestone for its high-voltage transmission cable factory: the exterior structure of the 430-foot extrusion tower has been completed.

The tower is located near the back of ABB's planned 240,000 square-foot facility that will be located at the Commerce Station Business Park off NC Highway 115 in Huntersville.

This concrete tower, which will play an essential part in the manufacturing of transmission cable, stretches 430 feet into the air — about one and one-half football fields high.

Inside the tower is a vertical extrusion process that is the heart of the facilities operations. The tall tower centers the stranded metal conductor until the hot extruded insulation cools to ensure perfect concentricity of the cable.

The new cable facility will supply high-voltage and extra high-voltage transmission cables, for both AC and DC applications, to carry electric power underground as part of the nation's new smart grid. The new facility, located in the greater Charlotte metropolitan area, is scheduled for completion in late 2012.
