Product Characteristic
1. The iron core is made of silicon steel sheet with high quality, high performance and high magnetic conductivity, with low no-load loss.
2. High voltage winding adopts layer structure. Low voltage winding 500KVA and below is layer type, 630kvA and above products adopt new spiral type. High mechanical strength, balanced ampere turn distribution, strong short circuit resistance.
3. The positioning structure is added to the body to avoid displacement during transportation. At the same time, all fasteners areequipped with fastening nuts to ensure that the fasteners are not loose during long-term operation.
4. This product is a fuly sealed structure. The vacuum oilfling process is adopted when the transformer is packaged, which completelyremoves the moisture in the transformer, ensures the isolation of the transformer oil from the outside air, prevents the aging of theol, and improves the operation reliability of the transformer, The product is equipped with pressure relief valve, signal thermometergas relay and so on to ensure the safe operation of the transformer.
5. Corrugated oil tank is adopted. This kind of oiltank has the advantages of simple process, high mechanical strength, good weldingeffect and no leakage. And because of the strong fluidity of the oil, the heat dissipation capacity of the product is improved.
6. The product is beautiful in appearance, small in volume and small in floor area. it is an ideal maintenance free product.
