Structural characteristics
The configuration structure is shield type, winding number is double winding, iron core structure is shell type, power supply phase number is three phase, iron core shape is E type, the processing is customized type, the cooling form is oil-immersed, frequency characteristic is medium frequency, the application range is mine, moisture-proof way is sealed.
Material
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.
