Product Details

3 phase 1000kva power 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 3 phase 1000kva power 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.

Details of 3 phase 1000kva power distribution transformer

Summary

The three-phase oil-immersed distribution transformer applies new type insulating structure and makes short-circuit resistance strong. The iron core is made of high-quality cold-rolled silicon-steel plate. High voltage winding group is made up of high quality oxygenfree copper lines and it adopts multilayered

drum type structure. All fasteners have been processed with special treatment to prevent them from loosening

Reliable Structure

Spiral loops with longitudinal oil path to produce a better interior cooling effect; Improve the effectual support of the loop’s terminal face to strengthen the anti-short circuit electricity capability; New suspending structure and instrument-positioning frames to guarantee that the long distance transport and movement will be more reliable.

Excellent Materials

Oxygen-free copper lines of lower resistivity, which will become smoother and burr-free after series of additional surface treatment, so the load loss of our transformer is lower and the electric performance is better.
High-quality silicon-steel plates which are of lower unit loss, and the no-load of the transformers is lower.
High-quality wooden laminating insulation pieces, which won’t split or move even under the influence of short

circuit.Thoroughly filtrated transformer oil containing less water, gas and impurities, which makes our transformers work better.High quality rubber sealing material, which can prevent the transformers form aging or

leakage.
