National Geographic Channel to Feature Southwire's Superconducting Cable

Carrollton, Georgia, January 15, 2009 -- Southwire's high-temperature superconducting cable, HTS

Triax®, is about to make its national television debut.

A new documentary produced by the National Geographic Channel provides a glimpse of cutting-edge

technologies being designed by the U.S. Department of Homeland Security and various partners to combat

and deter terrorist attacks within America's borders. Hi-Tech War on Terror is scheduled to air at 10 p.m. on

Wednesday, Jan. 28.

From military weapons labs to seaport and airspace command centers, the hour-long documentary includes

footage from facilities across the country. Viewers get a first-hand look at new technologies designed to

protect airliners from explosions, create a high-altitude missile detection system, add security sensors to

shipping containers, build an electrical grid using superconducting cables and scan people from a distance

to determine if they have malicious intentions.

“This is really cutting-edge stuff. This is brand-new science,” said James Cohen, Department of Homeland

Security under secretary. “We're going for the big gain. If we fail, we've learned in the process. But if

we're successful, it's a game-changer.”

While it is cutting-edge, Southwire's high-temperature superconducting (HTS) cable is not a brand new,

unproven technology. The company began working on superconducting cables in the early 1990s and is

about to mark two-and-a-half years since one of its HTS cables was installed in a working substation near

Columbus, Ohio.

According to the president of the Southwire Energy Division, Charlie Murrah, "The success of HTS Triax

cable operations at AEP in Ohio is helping the Energy Division leverage this experience to win new

superconducting cable projects across the United States. We continue to provide innovative solutions, like

HTS Triax, to solve our customers' most challenging problems."

Although it does not mention Southwire by name, the documentary explores a partnership between

American Superconductor, Consolidated Edison and Oak Ridge National Laboratory to develop a more

resilient power grid in the Manhattan borough of New York City. Southwire and its joint venture partner

nkt cables are working with American Superconductor to develop cables for the project. The

superconducting cables, which are seen in the film, act as their own circuit breakers, preventing a cascading

effect in the event of a power outage and limiting the area affected.

“As the nation's power grows even more congested, the ability of superconductors to deliver more power to

more people becomes increasingly crucial to ensuring a continuous flow of electricity,” said Stu Thorn,

Southwire's president and CEO. “In addition, power systems will require greater levels of protection

against electrical surges. To meet these challenges, partners like Southwire, American Superconductor and

the Department of Homeland Security are using the latest technological advances to provide solutions.”
