66kV Oil-immersed Power Transformer 40 mva transformer

Oil immersed transformer is a new type of high-performance transformer with a more reasonable structure and better performance. Its three-dimensional coiled iron core has no air gap in its magnetic circuit due to the three-dimensional arrangement of its three core columns in an equilateral triangle. The winding is tighter, and the three magnetic circuit lengths are the same and the shortest. The cross-sectional area of the iron core column is closer to a circle, thus further improving performance, reducing losses, noise, balancing the three aspects, and reducing the third harmonic component. This product is more suitable for urban and rural, industrial and mining enterprise power grid transformation, and is more suitable for combination transformers and prefabricated substation transformers. The main components of a transformer include iron core, winding, oil tank, oil pillow, respirator, explosion-proof tube (pressure relief valve), radiator, insulation sleeve, tap changer, gas relay,…
