275MVA power transformer control cabinet. The implementation included the production and prefabrication of 2 switchboards in accordance with the IEEE C57.148 standard for an energy company in the USA. Thanks to the use of thermal insulation in the housing, heating costs are saved and the switchgear operates uninterrupted in frosty conditions.
