Abstract

"DUTO DE REFRIGERAçãO INTEGRADO PARA BOBINAS DE TRANSFORMADOR DE DISTRIBUIçãO ENCAPSULADAS EM RESINA". A invenção refere-se a bobina de transformador encapsulada em resina, do tipo seco, que inclui múltiplas camadas de uma extensão de material condutor, e múltiplos dutos de refrigeração que são formados de material termoplástico e espaçados entre as camadas de material condutor. O material termoplástico que forma os dutos de refrigeração e a resina que encapsula as múltiplas camadas de material condutor são térmica e eletricamente compatíveis.
