ABB is a leader in voltage and power extensions
Power transformers are a very important part of ABB's business, as well as that of the original corporations that came together to form ABB. This merger created a unique opportunity to integrate the vast experiences and different technical competencies from all the founding companies. Prior to 1900, these companies pioneered different aspects of power transformer development. In 1893, ASEA, one of ABB's parent companies, supplied one of the first commercial three-phase transmissions in Sweden from a hydro power plant to a large iron ore mine some 10 km away. Transformer manufacturing soon emerged in most countries in Europe and in the United States. ASEA, BBC and other predecessor companies rapidly gained expertise in the manufacturing and installation of transformers. Today, ABB draws upon 700 years of combined experience of transformer design and manufacturing.
