Grid Upgrades Fight Blackouts - 2004

Southwire solutions move more power more reliably.

Blackout! Utility planners will remember August, 2003 for a long time. When 21 power plants dropped off line, 50 million people in eight states were affected – and billions of dollars in revenue were irretrievably lost. The big question: How do we keep that from happening again?

“Southwire solutions can help with the power system modernization that’s crucial to avoiding future blackouts,” says Nick Ware, technical director of Southwire’s Energy Division. “Southwire manufactures cable products today that, through increased capacity, can alleviate stress on the nation’s power grid. And Southwire engineering services can help design advanced transmission and distribution systems using conductors that perform to higher standards than more conventional constructions.”

High-capacity overhead conductors boost capacity

ACSS/TW (Aluminum Conductor, Steel Supported/Trapezoidal Wire) conductors can increase grid capacity significantly without major construction. ACSS/TW carries the entire cable weight on a steel core that allows continuous operation up to 250° C. Trapezoidal cross-section wires increase conductor area. The result: Capacity increases of 50 to 100 percent with no increase in cable diameter, no tower modifications, no right-of-way hassles and no environmental impact. Even bigger increases come with minor tower changes.

Temperature-sensing fiber optics monitor grid capabilities

Should you take on that short-term power-transfer contract? Temperature-sensing fiber optics embedded in current-carrying overhead conductors show how much spare capacity you really have, with accurate, span-by-span temperature profiles.

Underground high-voltage simplifies expansion

Permitting new overhead conductors can be tough. Underground high voltage using extruded-dielectric cables is low-maintenance and environmentally friendly. Forte Power Systems, a Southwire company, is the only North American producer of extruded-dielectric cables up to 230kV. Complete turnkey solutions are available.

Superconductors promise urban power boost

High-temperature superconducting (HTS) cables can increase urban power capacity in existing rights-of-way. Southwire, a pioneer in the field, believes HTS cables will be an integral part of future transmission systems. Southwire has been powering key manufacturing plants via an operating an HTS system for over four years, and commercial availability is expected within five years.

Southwire has compiled a collection of articles and fact sheets on these power transmission solutions, and it’s available on a convenient CD that plays on your PC*. The presentation includes a short video, product sheets and contact information. For your copy of the Southwire energy solutions e-card, contact your Southwire representative.
