Abstract

TRANSFORMADOR DO TIPO SECO. A presente invenção refere-se a um transformador do tipo seco que compreende pelo menos um enrolamento de alta tensão e um enrolamento de baixa tensão que interagem por meio de um campo eletromagnético. Cada enrolamento é constituído pelo enrolamento de condutores, o enrolamento de alta tensão e o enrolamento de baixa tensão tendo uma distância definida entre si, espaçadores (10) sendo previstos entre os elementos para manter a dita distância. A invenção refere-se, ainda, a um processo para produzir os espaçadores (10).
