35kV oil-immersed transformers (315-63000kVA) are mainly used in the national power grid, new energy power generation, petrochemical, metallurgy, mining, transportation and other fields.

1. The iron core is made of high-grade high-quality cold-rolled grain-oriented silicon steel sheet, and the multi-step joint structure is adopted, resulting in much lower noise than the national standard.

2. The production process of the coil and the body adopts the "set type" technology, which strictly controls the magnetic center line of the coil to be the same, the turns are well balanced, and the short circuit resistance is strong;

3. The rigid six-sided positioning of the body meets the assessment of harsh transportation environment without displacement or deformation. All sealing surfaces are made of gold processing + sealing groove limit structure to improve the sealing life.
