NLMK Group, NLMK Group, a Metal-Expo regular exhibitor, a global steel company, has delivered premium laser-treated electrical transformer steel to SVEL Group, a leading Russian manufacturer of electrotechnical equipment. NLMK steel was used to make a 630 MVA three-phase potential transformer for the Krasnoyarsk Hydro Power Plant.

Built in 1972, Russia's second-largest hydro power plant, the Krasnoyarsk HPP, is located on the Yenisei River near Divnogorsk. It supplies power to the Krasnoyarsk Aluminium Smelter. Currently, the hydroelectric power plant is undergoing a comprehensive upgrade to install superpower transformers. By 2024, NLMK plans to supply close to 2,000 tonnes of steel to SVEL for the production of six more transformers. NLMK steel properties will enable a reduction in specific magnetic losses in transformers of up to 15% compared to commercial grades.
