1. Low loss, and significantly energy-saving. The average no-load loss is 35% lower than prescribed by National Standard GB/T 6451-2008.

2. The core laminations are made up from high-quality cold-rolled grain-oriented silicon steel sheets with chamfered joints and without punched holes, and are stacked without the upper yoke sheets in place.

3. Zigzag directed flow of oil are provided within the windings

4. The regulating winding is a separate winding which apart from the high voltage main winding

5. The windings of one phase are assembled into an integral phase block before placing into the core.

6. Core frames in the form of a flat plate are used for clamping the core, and are joined together by side beams. The core and coil assembly is fixed in the tank, being positioned against the tank at six sides rigidly

7.Transformer tanks are fabricated with steel plates wide enough so that there are no weld joints on each surface.

8.Diaphragm membrane is provided within the conservator, preventing direct contact of oil with air, protecting the oil from aging

9.Reliably sealed, and fine machined for sealed surface. Used double gasket grooves in their jointing surface and kept tight with high quality gasket material. If required by the customer, the upper and lower part of the tank can also be welded tight

10. Quality assurance rules are also observed for all insulating parts,and main components
