| ABB won $39 million contract in Dubai ABB, a European engineering giant based in Zurich, has been awarded a $39 million contract by Dubai Aluminium Company (Dubal) to upgrade rectifier, transformer and automation systems at its 480-hectare smelter complex in Dubai. The project includes replacing five high-voltage regulating rectifier transformers (rectiformers) with larger units rated at 86 megavolt amperes (MVA), to increase capacity and allow Dubal to combine two smelting potlines. Rectifiers are devices that convert alternating current (AC) to direct current (DC). ABB is also supplying control and protection systems as well as 250 kiloampere (kA) field-oriented measuring equipment. ABB will upgrade existing systems including high-voltage cables, low-voltage and control cables, fire-detection and fire-fighting equipment. Dubai Aluminium operates the largest single-site aluminum smelter in the Western world, with an annual output exceeding 850,000 metric tons. Commissioning of the new ABB systems will begin during July 2007 and is set for completion in March 2008. write your comments about the article :: © 2006 Construction News :: home page |
