Abstract

A presente invenção refere-se a um transformador (1) que compreende um tanque (10) que possui um volume fechado (11) com um material isolante (13), o tanque (10) compreendendo pelo menos um canal (25) que se estende através do tanque (10), no qual o interior de pelo menos um canal (25) é separado do volume fechado (11) do tanque (10) por uma parede do canal (17). Um núcleo do transformador (30) é provido fora do volume fechado (11), o qual compreende pelo menos uma perna de núcleo (32) que se estende através do tanque (10) por pelo menos um canal (25). Pelo menos uma bobina (50, 52) está localizada dentro do volume fechado (11), a bobina (50, 52) sendo enrolada em torno de pelo menos um canal (25), no qual o tanque (10) possui uma parede interna ou uma parede externa (16) que compreende uma camada muito pouco condutiva (40), a qual possui fibras (42) embutidas em um material de impregnação (44).
