10kV Dry-type Distribution Transformer

Overview of Epoxy Numerical Casting Dry Type Power Transformer The transformer was introduced in 1886. Due to the technical level at that time, dry type transformer could not achieve high voltage and large capacity, and it was difficult to meet people's needs. They were gradually replaced by oil immersed transformer. The birth of epoxy resin, a chemical raw material, changed this situation. Epoxy comfort is adopted by the electrical manufacturing industry for its unique flame retardancy and combustion-supporting characteristics. Since the first epoxy cast dry transformer was manufactured in Germany in 1994, this technology has been continuously promoted to the world. Since my country's dry transformer manufacturing technology is mainly introduced from Germany and other European countries, most of the dry transformers produced nationwide are epoxy cast. Epoxy resin dry-type transformers have the following advantages: (1) High insulation strength: Cast epoxy resin has an insulation bre…
