Anti-corrosion and protection of American box transformer shell

American box substation, its box body adopts anti-corrosion design and special spray paint treatment, which can be applied to various harsh environments, such as stormy and highly polluted areas. The box body has gone through eight pretreatment processes before painting, and then seven painting and baking processes are completed, which shows its cautious attitude towards anti-corrosion. At present, the shells of American box substations produced in China have almost no special treatment. They basically adopt electrostatic spraying treatment after pickling. Some companies even do not even pickling treatment. What's more, they only do it on the outer surface. It is conceivable that the spray paint treatment has the anti-corrosion ability of its shell. Even with electrostatic spraying, there are often dead corners when the bottom surface is processed, and it is difficult for electrostatic spraying to spray powder on these untreated parts, so it will inevitably leave hidden dangers of rust. As the box transformer has to work in the outdoor environment of wind, rain and sun for many years, if the surface treatment is not good, the rust will be very serious. This problem is very important, and it is also a topic that has been very concerned, valued, and researched in China for decades. Therefore, many manufacturers have adopted some other technologies to solve this problem. Regarding protection, the transformer oil tank and heat sink of the American box substation are partially exposed to the outside, the purpose of which is to improve the heat dissipation conditions. However, since it is directly exposed to the sun, under the heat radiation of the sun, will it affect the temperature rise? It has not been introduced in detail. In addition, the exposed parts are easily damaged by collisions and knocks from external forces. If it is damaged, a large amount of transformer oil will be lost, and the consequences will be disastrous. Therefore, some domestic manufacturers wrap a layer of steel plate on the heat sink in order to increase the protection capacity.
