Эпоксидные смолы для электроэнергетики
У данного типа трансформаторов, как минимум одна обмотка залита эпоксидной смолой. Делается это при помощи литейной формы, которая находится в автоклаве, в условиях, близких к нулевому давлению. Другая обмотка также может быть залита эпоксидной смолой или, как альтернатива, пропитана полиэфирной смолой класса H с высокой степенью отвердевания.
Благодаря технологическим достижениям последних лет, трансформаторы с литой изоляцией отличаются повышенной надежностью.
