Electrical equipment for world’s most efficient aluminium factory
Germany: Siemens is supplying a VB1 high-current switchgear with vacuum switching technology and the high-current supply unit for production for the world’s most climate-friendly, energy-efficient aluminium smelting plant being built on Norway’s Karmøy peninsula.
High-current and generator switchgear with vacuum switching technology protects transformers and generators from overvoltage and short-circuits, as the vacuum circuit-breakers interrupt the arc in a high-vacuum interrupter tube, according to the manufacturer.
The new aluminum factory on Karmøy will produce 75,000 tons of aluminum per year and consume about 1 terrawatt hour (TWh) of electricity per year, thus placing high demands on all of the electrical equipment.
Siemens was already commissioned last year to supply the main transformers for this project.
