Product Specification

SCB13 Dry Type Transformer, Power Transformer Manufacturer, Dry Type Electrical Transformer

1.Product Description

With capacity from 30KVA to 1,600KVA, the three-phase 10kv oil-immersed transformer is made under advanced production technology.

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.

Advantage of materials

1.because we use 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.

2.We use high-quality silicon-steel plates which are of lower unit loss, and no-load of the transformers is lower;
3.We use high-quality wooden laminating insulation pieces, which won't split or move even under the influence of short circuit;
4.We use thoroughly filtrated transformer oil containing less water ,gas and impurities, which makes our transformer work better;
5.We use high-quality rubber sealing material, which can prevent the transformers form aging or leakage;
6.All materials has passed the quality testing, and all the raw material factories has pass through the national standard ISO9000 inspection.
Advantage of technology

Improved from S9 series product, S11 series product reduce the no-load loss by 30%,no-load electric current by 70~85%, average temperature by 10K,nosie level by 2~4db, and double the products service life. even under 20% overloads, it can also work for long period of time .

4, Structural Features

• 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, highmechanical strength andstrong short-circuit resistance.
• The iron core and windingare 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.
• 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.
• 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 reducesheight of the transformer.
• 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.
• 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.
