The core is made of high-quality, high-performance silicon steel sheets, with low no-load loss.
The high-voltage winding adopts a layered structure, with high mechanical strength, balanced distribution, and strong short-circuit resistance.
The overall structure is fully sealed, and the vacuum oil filling process is adopted to ensure that the transformer oil is isolated from the outside air, prevent oil aging, and improve the reliability of transformer operation.
The corrugated oil tank is used, which is simple to process, has high mechanical strength, good welding effect, no leakage, and good heat dissipation capacity.
It has beautiful appearance and small size, and is widely used in urban and rural power grids.
