High efficiency Low price Oil-immersed three phase transformer exclusive for petrifaction

Information	Description
Summary	the oil tank is made by fine cold-rolled steel sheets; corrugation oil tank automatic production line is adopted ; rust cleaning and phosphate treatment are applied for the surface of the oil tank, then , antiseptic coating material is applied on the surface, which can meet the requirements for petroleum and chemical industry(much oil stain and many chemical substances). In addition , the corrugations not only possess heat radiation function , but also meet the requirement for oil expansion and oil contraction under normal performance . The isolation from air guarantees a low aging speed of oil and a long life expectancy of transformer.
Reliable Structure	the cover is manufactured by welding fine steel sheets: rust cleaning and phosphate treatment are applied for the surface to avoid the corrosion caused by oil stain and chemical substances; the cover possesses a pretty external appearance; the installation and maintenance for the cover is very easy and convenient , so it can be used in places where the outdoor surrounding is not very good.
Excellent Materials	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.
