The iron core is made of high-permeability oriented electrical steel, and the windings are made of insulating materials above grade A; the cooling liquid is mineral oil, and the fully-sealed structure isolates the transformer oil from the atmosphere, effectively reducing the overall aging of the transformer and prolonging product life. It is suitable for outdoor and indoor installation, and can also be matched in box-type substations.

 Heat resistance grade: A grade.
