Complete Product Introduction
1. Product Brief Introduction
The three-dimensional core oil-immersed transformer (S13-M.R series) is a new type of high-reliability transformer product with more reasonable structure, better performance and lower production cost. This product breaks through the traditional planar structure and adopts a three-phase symmetrical three-dimensional structure. Moreover, due to the absence of air gaps in its magnetic circuit, the magnetic conduction direction of the silicon steel strip is completely consistent with the magnetic circuit direction. The three cores are arranged in an equilateral triangle three-dimensional form, and the three magnetic circuits are of the same length and the shortest. It also has the characteristics of no waste in the processing and assembly process; therefore, it is an energy-efficient transformer with lower noise, more compact structure and using traditional materials. Its outstanding performance in reducing loss and saving materials is fully in line with China's energy conservation policy.
