10kv 12kv 20kv Oil Immersed Transformer 3 Phase Full Sealed With 50/60Hz Frequency

Product Description

10KV oil immersed transformer

Product introduction

The product complies with the national standard GB1094-1996 and GB /t6451-2008. This is the latest series product with low loss copper winding. It is made of high-quality materials. New technology and materials are used for coil body and insulation. This product shows advantages of low loss, low noise and high efficiency, and can achieve good energy-saving effect and reduce pollution.

·Service conditions

1. The maximum ambient air temperature shall not exceed 40 ℃, and the minimum shall not below - 25 ℃;

2. The altitude shall not exceed 1000m. If special customized transformers and low-voltage components are used, the altitude can reach 4000m;

3. The vertical inclination is no more than 5 °, and no violent vibration and impact;

4. The air humidity is not more than 90% (+ 25 ℃);

5. No gas and conductive dust that will seriously affect the insulation of transformer, no explosion hazard and corrosion of electrical components;

6. Outdoor wind speed shall not exceed 35m / s.

7. If service conditions beyond the above, specially customized product is available.

·Structural features:

1. The low-voltage winding of an oil immersed transformer, except for copper conductor used for small capacity transformer, generally adopts copper foil winding and extraction hydro-cylinder structure; and the high-voltage winding adopts multi-layer barrel structure. These result in evenly distributed ampere-turns, small magnetic flux leakage, high mechanical strength and strong short-circuit resistance.

2. The iron core and winding are fastened separately. The machine height, low-voltage lead and other fastening parts adopt self-locking locknut and non-suspension structure, which can withstand impact during transportation.

3. The coil and iron core are treated by vacuum-drying, and the transformer oil is filtered and oiled in vacuum to reduce the water content inside of the transformer.

4. The oil tank is made of corrugated plate, which could absorb oil to compensate temperature fluctuation caused by oil volume change. Therefore, this product has no external oil tank, which significantly reduces height of the transformer.

5. As the corrugated plate replaces the oil storage tank, the transformer oil is isolated from the outside world, effectively preventing entry of oxygen and water and resulting in the decrease of insulation performance.

6.The above five performances enables the oil immersed transformer no need to change oil in normal operation, greatly reducing the maintenance cost , and extending the service life of the transformer.
