500kva outdoor current power transformer manufactuer

500kva outdoor current power transformer manufactuer advantage:

1. Low loss, and significantly energy-saving.

2. The core laminations are made up from high-quality cold-rolled grain-oriented silicon steel sheets

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.

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.

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