S9 Series 1250KVA 22KV/0.4KV oil filled three phase distribution transformer

S9 Series 1250KVA 22KV/0.4KV oil filled three phase distribution transformer

I. Introduction:

1.Iron core pole is rolled by HV & LV, which maked the winding solid.

2.Corrugated panel radiator, when temperature change, it could replace the oil conservator.

3.Iron core structure is made of 3 phase 3 pole inside and outside roll with high machine strength.

4.A fully enclosed structure transformer tank, fuel tank along with the boxes available Bolt or welded, transformer oil is not in contact with air to extend the service life.

II.Working condition:

1.Altitude cannot exceed: 1000m

2.Lowest outdoor temperature: -25°C

3.Highest ambient temperature: +40°C

4.Highest daily average temperature: +30°C

5.Highest annual average temperature: +20°C

Advantage of S9 Series 1250KVA 22KV/0.4KV oil filled three phase distribution transformer

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.
