load regulating power transformer is developed and produced according to the requirement of the market. It 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.
High reliability, advanced level of performance, economic indicators and reasonable;
Using phase-shaped core of three joints, curing paint brushing the surface to reduce wear and tear and noise;
Winding structure of a new oil road design is reasonable, with the new insulation to improve the mechanical strength and the ability to engage in short-circuit;
Tank forms, beautiful, generous.
