Molten Splash Protection for EAF Power Cables

The Problem

When a water cooled power cable is used in severe environments such as powering an EAF (electric arc furnace) in a steel mill, there is an enormous potential for heat, flames, ash or molten splash to damage the electrical cables (or series of cables) thus crippling the melting operation. This damage translates into unscheduled maintenance and lost production time. In some instances these costs have been estimated as high as $100,000 per hour, depending on the size of the operation and production schedules.

Water-cooled power cables provide a flexible source of power to permit movement of the electrode arms up and down, and to allow swinging the electrode arms and roof back and forth when charging the furnace. A low temperature rubber ja View the rest of this article
