Abstract

NÚCLEO DE TRANSFORMADOR E MÉTODO DE MONTAGEM DO MESMO PARA ALTA EFICIÊNCIA E ALTO DESEMPENHO ANTICORROSÃO, E TRANSFORMADOR. A presente invenção refere-se a um núcleo (102) de transformador (100) para transformador do tipo seco que inclui uma construção laminada com vários grupos de laminações empilhadas que formam uma sequência "step-lap" (925) de laminações. Cada grupo na sequência "step-lap" tem um comprimento médio diferente de um grupo adjacente na sequência "step-lap" e tem pelo menos duas laminações idênticas por grupo, em que pelo menos um grupo tem pelo menos quatro laminações idênticas. Método (1400) de montagem de um núcleo de transformador também são providos, assim como outros aspectos.
