The iron core is made of high-permeability oriented electrical steel, the three-phase magnetic circuit is symmetrical, and the windings are made of insulating materials above Class A; the cooling liquid is mineral oil, and the fully-sealed structure isolates the transformer oil from the atmosphere, effectively reducing the overall transformation of the transformer. Aging to extend product life. It is suitable for outdoor and indoor installation, and can also be matched in box-type substations.
Features: three-phase magnetic circuit balance, low noise, small no-load current.
Heat resistance class: F class, H class
