American Superconductor begins production test run of HTS wire

17 April 2002 – American Superconductor Corporation (Nasdaq: AMSC), a global supplier of superconductor products and power electronic systems for the electric power industry, today announced it has released the first high temperature superconductor (HTS) wires for initial production at its new manufacturing facility in Devens, Massachusetts. The HTS wires will be fully processed under actual production conditions to provide rigorous verification of the manufacturing process.

The 355,000 sq. ft. manufacturing facility is the first high volume, commercial HTS wire manufacturing plant in the world with the capacity to meet the needs of the growing HTS market. AMSC received a certificate of occupancy for the plant in December of 2001. Since that time the company has been commissioning individual pieces of equipment up to a full production run-through of the manufacturing process. When it is fully equipped, the facility will be capable of producing 20,000 kilometers (12,000 miles) of HTS wire annually.

“This release to production is a key milestone in the commissioning of our new manufacturing facility,” said Greg Yurek, chief executive officer of American Superconductor. “We’ve completed testing of the equipment and are moving to the next phase of bringing the facility on-line. As volume production ramps towards the end of the year, we will continue to drive down the price of high-performance HTS wire, which will open up broader markets for our industry- product.”

HTS wires offer compelling advantages in applications such as utility generators, ship propulsion motors and electric power cables. Because AMSC’s HTS wires conduct significantly more electricity, up to 140 times the electrical current of similar sized copper conductors, they will change the generator and motor industries through major reductions in initial and operating costs, size and weight. Similarly, HTS power cables will benefit electrical transmission networks by opening up the power bandwidth of existing rights-of-way and alleviating grid congestion.

Transforming raw HTS materials into wire involves repeated mechanical deformation processing of a metal bar, or billet — typically about three feet long and four inches in diameter — drawing it into a narrower and narrower strand until the single metal billet is transformed into a continuous wire that extends over 3 kilometers (2 miles).

“Over the coming months, results of our production tests are expected to validate the new manufacturing process and allow our engineers to continue fine-tuning equipment as we prepare to ramp-up into commercial production,” Yurek added. “We expect this work to last through the fall, with actual production line output available for commercial sale expected by year’s end.”
