20kv distribution power transformer can be widely used in urban & rural, industrial & agricultural power network, which has a great significance for energy-saving and environment protection. The lamination method of this product's iron core is ladder form, instead of the traditional iron core lamination technology, which improves the magnetic circuit distribution inside the iron core. It can be seen as a revolution of transformer iron core manufacturing. Compared with the traditional, the no-load loss, no-load current and noise of the new one decrease 20% respectively, and load loss decreases 10%. The new product applies CAD, with advance design, reasonable structure, and excellent materials.
Each index complies with the standards of GB1094-1996 "Power Transformer" GB/T6451-1999 "Technical Parameters and Requirements of Three-phase Oil-immersed Type Power Transformer". Now its level is n the leading position of our country.
