As nossas vantagens<\/h2>\n

Design da bobina em espiral:<\/h3>\n

As nossas bobinas s\u00e3o concebidas com condutas de \u00f3leo longitudinais que proporcionam uma dissipa\u00e7\u00e3o de calor muito boa, baixa fuga magn\u00e9tica e elevada resist\u00eancia mec\u00e2nica. Isto melhora consideravelmente a capacidade de resist\u00eancia do transformador contra curto-circuitos.<\/p>\n

N\u00facleo de alta efici\u00eancia:<\/h3>\n

O n\u00facleo de ferro utiliza chapas de a\u00e7o sil\u00edcio empilhadas (menos de 0,35 mm de espessura) com elevada condutividade magn\u00e9tica. Isto reduz as perdas em vazio e a corrente, melhorando a efici\u00eancia.<\/p>\n

Isolamento de alta qualidade:<\/h3>\n

Utilizamos materiais de isolamento resistentes a altas temperaturas que podem suportar sobretens\u00f5es e sobrecorrentes durante o funcionamento, garantindo um desempenho duradouro e seguro.<\/p>\n

\u00d3leo de transformador:<\/h3>\n

O nosso \u00f3leo tem baixa viscosidade, excelente transfer\u00eancia de calor e propriedades de isolamento superiores, protegendo o n\u00facleo e os enrolamentos, retardando o envelhecimento do isolamento e prolongando a vida \u00fatil do transformador.<\/p>\n

Tanque de \u00f3leo ondulado:<\/h3>\n

Fabricados a partir de a\u00e7o laminado a frio de qualidade superior, os nossos reservat\u00f3rios de \u00f3leo ondulados s\u00e3o tratados para maior durabilidade e revestidos com tinta tripla - \u00e0 prova de chuva, \u00e0 prova de humidade e \u00e0 prova de pulveriza\u00e7\u00e3o de sal - aumentando a fiabilidade e reduzindo os custos de manuten\u00e7\u00e3o.<\/p>\n

Veda\u00e7\u00f5es fi\u00e1veis:<\/h3>\n

Utilizamos vedantes de borracha de alta qualidade para evitar eficazmente fugas de \u00f3leo e impedir a entrada de ar exterior, retardando o processo de envelhecimento e garantindo o desempenho do transformador.<\/p>\n

Aplica\u00e7\u00f5es dos enrolamentos de transformadores<\/h2>\n

Ajuste da tens\u00e3o ou da corrente: Os transformadores podem aumentar ou diminuir a tens\u00e3o ou a corrente num circuito de corrente alternada.<\/p>\n

Controlo de imped\u00e2ncia: Pode ajustar os valores de condensadores, indutores ou resist\u00eancias num circuito de corrente alternada.
\nIsolamento DC: A tens\u00e3o CC n\u00e3o pode passar entre circuitos atrav\u00e9s de um transformador.
\nIsolamento el\u00e9trico: Mant\u00e9m dois circuitos eletricamente separados, garantindo assim a seguran\u00e7a durante o seu funcionamento.
