ALUMINUM AUTO PARTS & MOTOR-CYCLE SPARE PARTS BY DIE CASTING

The Key Selection points of Oil-Immersed Distribution Transformer . Load Properties of Distribution Transformer: 1) When there are a large number of primary or secondary loads, it is advisable to install two or more transformers. When one transformer is disconnected, the capacity of the remaining transformers can meet the demand of primary and secondary loads. First, the secondary loads should be concentrated as far as possible and should not be too dispersed. 2) When seasonal load capacity is large, special transformer should be installed. For example, in large civil buildings, the load of air conditioning refrigerators, heating electricity and heat, etc. 3) When the concentrated load is large, special transformer should be installed. Such as large heating equipment, large X-ray machine, electric arc furnace, etc. 4) When the lighting load is large or the power and lighting use common transformer seriously affects the lighting quality and lamp life, special lighting tra

15 Problems of Transformer Tank Painting

After assembling and welding spare parts of transformer tank, we will do surface treatment for it. The surface treatment normally is Painting and Powder coating. There are 15 problems always happen and affect the quality of transformer tank in the painting processes: 1.Transformer Tank Painting has Pinholes. It is caused by the air bubbles mixed in the paint film and the bursting of other bubbles, which can not be leveled before the film is dried (cured), and also by the improper treatment of the transformer tank steel sheet or coating (too thick paint film, etc.). 2.Transformer Tank Painting with Bubbling. Gases such as air or solvent vapor formed during the coating process. This kind of foam can disappear or exist permanently during the drying process of the paint film. 3.Transformer Tank Painting with Blushing. In the drying process of glossy coatings, the film sometimes appears milky white. This is due to the condensation of water in the air on the surface of w
