Asea AB, an industrial jewel of Sweden, was created in 1883. Asea’s business was broadly defined as "the generation and application of electric power". The company manufactured such diverse items as steam turbines for power plants and high-speed electric locomotives for passenger railroads. In 1986, Asea extended the firm’s engineering and manufacturing operations beyond Sweden in order to gain economies of scale - both in manufacturing and in raising capital.

The big step forward had been the acquisition in Finland of Strömberg AB with its 7,000 employees, which was followed in late 1987 by the acquisition of 63 percent of EB Corporation in Norway. By 1987, Asea was radically altered from a Swedish-centered company to a pan-Nordic electrical multinational. But the company continued to look even beyond the Nordic countries. In 1987 Asea and Brown Boveri were of roughly equivalent size in many respects (annual sales, net worth, number of employees) and had adopted similar lines of decentralized command. The companies also complemented each other in their geographical concentrations and in management strengths.

This marriage of equals in 1988, Asea and Brown Boveri into ABB, allowed the new company to stay at the forefront of technology. Utilizing production plants in many countries, the merged group made the most of the advantages of international specialization and became the world's leading supplier in the electric power industry.


ASEA Brown Boveri

ABB Asea Brown Boveri, was the result of a merger between Asea AB of Sweden and BBC Brown Boveri Ltd. of Baden, Switzerland in 1988. The merged entity became the world’s leading supplier in the $50 billion electric power industry. It successfully integrated 850 subsidiary companies and 180,000 employees operating in 140 countries. When ABB was formed its two parent companies retained their separate names, boards and stock listings.

In 1996 ASEA AB in Sweden and BBC Brown Boveri AG in Switzerland decided to change their names to "ABB AB" and "ABB AG," respectively. 

Bailey Network Management

The name Bailey Network Management has long been associated with excellence in Energy Management and SCADA systems used primarily in the electric power industry.

This heritage provides a wide range of hardware, software, and full-service solutions for the railway, gas transportation, hydroelectric, and petrochemical industries. Although the familiar Ranger and Vanguard names have been retired, the same attention to detail and robust technology that made these names the leaders in the industry is assured.


BBC Brown Boveri Electric

The American operation of Swiss-based Brown Boveri Limited was called Brown Boveri Electric Company, incorporated as a U.S. company. In 1984, the U.S. company name was changed to BBC Brown Boveri Inc. Brown Boveri Electric continued innovating in the field of stored energy low- and medium-voltage circuit breakers and 5 kilovolt (kV) air magnetic circuit breakers. Manufacturing a complete line of low- and medium-voltage indoor and outdoor products in addition to high-voltage circuit breakers and switches, the company was known for technical innovation and engineering excellence. In 1988, the name changed again following the merger of Swedish ASEA, and Swiss BBC.

The new company ASEA Brown Boveri grew considerably when the transformer and relaying businesses of Westinghouse Electric were added to the American operation. 


Brown, Boveri & Cie

Brown, Boveri & Cie (BBC) was a Swiss group of electrical engineering companies. It was founded in Baden, Switzerland, in 1891 by Charles Eugene Lancelot Brown and Walter Boveri who worked at the Maschinenfabrik Oerlikon. In 1970 BBC took over the Maschinenfabrik Oerlikon. In 1988 it merged with ASEA to form ABB.

The company produced DC and AC motors, generators, steam turbines, gas turbines, transformers and the electrical equipment of locomotives.

Elettrocondutture S.p.A.

As far back as the first half of the 20th century, Elettrocondutture S.p.A., with its head office in Milan, was one of the few leading Italian companies which marked the historical milestones of the low voltage plant engineering evolution. Back in the 1930s, under the guidance of the Calì family, it had already introduced the first Stotz-Kontakt automatic circuit-breakers in Italy. These represented the development of the first types of automatic protections, whose invention by the German company even dated back as far as the 1920s.

In 1950, when collaboration with BBC Brown Boveri had been strengthened, production was extended to remote switches and industrial relays and, at the beginning of the 1960s, immediately after the inauguration of the new factory in Milan, the Elettrostop residual current circuit-breakers were patented. These were the ancestors of the present series of residual current protection devices found in every domestic, service sector and industrial electrical installation.

The new factory in Pomezia was opened at the beginning of the 1970s. This worked alongside the one in Milan to produce the different series of circuit-breakers featuring the technological innovations which have progressively established themselves. The same period also saw introduction of the first series of miniaturised modular apparatus in Europe.

The automatic and residual current circuit-breakers, which represented the company’s traditional market, were placed side by side with a continuously widening range of products and systems: PLCs and other electronic equipment for industrial automation, switchboards, building automation systems, etc.

At the end of the 1980s, Elettrocondutture became part of the ABB Group where it has carried on developing and selling products and solutions, constantly keeping pace with progress of the technologies available and with the increasing new needs of all the operators in the electrical and automation sectors.

Kuhlman Electric Corporation

Kuhlman was founded in 1894. In that year, Mr. Etna Kuhlman with a start-up workforce of two men set up shop in Elkhart, Indiana. It was there that Kuhlman's very first transformer was designed and produced.

In 1915, Kuhlman moved its manufacturing operation to Bay City, Michigan, where it remained until that facility closed in 1975. Throughout the 1940's and early 1950's, with rural electrification and urban and industrial growth reaching record highs, the need for transformers rose greatly. Kuhlman's orders and backlog grew with this trend as well. After several much needed expansions to the Bay City plant and the addition of a new warehouse facility, Kuhlman was still faced with the "problem" of needing even more factory capacity. 

To expand their power transformer product line, Kuhlman opened the manufacturing facility in Crystal Springs, Mississippi just south of Jackson, Mississippi in 1956. This facility allowed Kuhlman to expand into the three phase small power transformer market. This was vital for rapid growth due to the distribution substation construction throughout North America. 

In July 1969, the Versailles, Kentucky plant began manufacturing distribution transformers for Kuhlman. In 1977, plans to expand the facility received corporate approval, and the project was completed in the latter part of 1978. This expansion increased capacity by about 20 percent to 250,000 square feet. Also in 1978, Kuhlman acquired Associated Engineering Company, an independent manufacturer of instrument transformers with facility near Charlotte, North Carolina.

In 1991, Kuhlman Corporation Headquarters moved from the Birmingham, Michigan facility to the Versailles location near Lexington, Kentucky in the heart of central Kentucky's lovely Bluegrass Region. In 1993, some of the company's Corporate HQ Division briefly moved to Savannah, Georgia, where they remained until the purchase of the Kuhlman Corporation (NYSE: KUH) by Borg Warner Corporation (NYSE: BWA) and the subsequent sale of Kuhlman Electric Corporation to The Carlyle Group in 1999. During the transmission market downturn of 1994, the oil-filled instrument transformers were moved to the Crystal Springs facility when Kuhlman consolidated instrument transformer manufacturing with the power transformers.

In August 2008, Kuhlman Electric was purchased outright from the Carlyle Group by ABB. In addition to Crystal Springs facility becoming part of our Power Transformer division, this facility also manufactures oil-filled instrument transformers.

Westinghouse Electric Corporation was founded by George Westinghouse in 1886. He devised the use of alternating current (AC) for electric power transmission. He was a prolific inventor, beginning with the air brake for railways in 1868, and then added 360 patents for railways, electricity and natural gas. He invented the gas meter and pioneered a control system of pipes to transmit natural gas into homes safely.

His hydroelectric development of Niagara Falls in 1896 initiated the practice of placing generating stations far from consumption centers. The Niagara plant transmitted massive amounts of power to Buffalo, New York, 20 miles away. To solve the problem of sending electricity over longer distances, Westinghouse developed the transformer. They are still used today to step up the voltage for efficient long-distance power transmission and then step it down at the point of use.

The electric transmission and distribution (T&D) business of Westinghouse Electric developed into a dominant and sustained industry leader in North America. In 1989, ABB acquired the T&D business of Westinghouse. This gave the company a leading production position for distribution and power transformers, instrument transformers, transformer components, high-voltage breakers, medium-voltage breakers and reclosers, surge arresters, and capacitors.
