Product Description

S11 3 Phase Oil Immersed 2mva 30-2500 kVA Electric Power Distribution Transformer,From professional manufacturers carefully built, welcome inquiry

1.Product Description

It is designed by corrugated plate instead of oil storage tank, thus oil is placed apart from the outside world. In addition, the coil and iron core are treated by vacuum-drying. All these features aim to get better insulation performance. In return, the transformer does not need to change oil in long term operation. Low maintenance cost, extended service life.

2.Main Functions And Features

-High reliability, advances level of performances, reasonable economical indicators.

-The core joints are of stepped shape with 3 steps, and the surface of the core is coated with cured paint to lower losses and noise.

-The winding has novel structure and its oil passage is reasonable designed. Its newly designed insulation structure helps enhance its mechanical strength and the short circuit withstanding ability.

-The oil tank is in various types, all have good outlook.
