▶ using the corrugated tank sealing structure, enclosure, to prevent contact with air, water in contact with the transformer, reducing the degree of aging of the oil, to extend the service life of the transformer; Through the elastic deformation of corrugated to adjust the volume change of transformer oil heat bilges cold shrink.

▶ the product structure for the outdoor type, oil-free pillow,anti-fouling high level; ensure safe operation and reliability of the grid.

▶ the transformer has a pressure release safety devices, when a transformer failure pressure is too high. It can be safely released reliably through the pressure relief valve to prevent the expansion of the accident.
