Abstract
ENROLAMENTO ELÉTRICO, TRANSFORMADOR SECO COM ESSE ENROLAMENTO ELÉTRICO E PROCESSO PARA PRODUÇÃO DE UM ENROLAMENTO ELÉTRICO.A presente invenção refere-se a um enrolamento elétrico (10, 20) para um transformador seco (1), que permite a construção de um transformador seco compacto, mesmo em classes de tensão mais altas. Para esse fim, o enrolamento elétrico (10, 20) apresenta uma pluralidade de espiras de um condutor de enrolamento (11), enroladas para uma bobina (15). A bobina (15) está embutida em um corpo de isolamento sólido (12). De acordo com a invenção, está previsto que sobre a superfície (13) do corpo de isolamento (12) está aplicado um revestimento (14) de um material eletricamente condutor.
