Abstract

<B>TRANSFORMADOR DE FORçA DE CABO ENROLADO E MéTODO DE RESFRIAMENTO A AR DO MESMO<D>. Um transformador de força (1) compreendendo um núcleo de transformador enrolado com um cabo de alta tensão, o qual é composto de um núcleo tendo várias partes de fios (112), uma camada interna semicondutora (113) envolvendo o núcleo, uma camada isolante (114) envolvendo a camada interna semicondutora (113), e uma camada externa semicondutora (115) envolvendo a camada isolante (114) em que o enrolamento é munido de espaçadores (4, 12) dispostos para separar cada espira de cabo na direção radial no enrolamento com a finalidade de criar ductos axiais cilíndricos de esfriamento (3).
