S□-M · RL series oil-immersed three-dimensional wound core transformer

On the basis of the core arrangement of the three-phase planar coil-core transformer, the 10kV oil-immersed three-dimensional coil-core transformer produced by Hezong Technology breaks through the traditional structural mode through magnetic circuit analysis and adopts the combination of three identical rectangular semicircular cross-section coil-core frames, realizing the completely symmetrical and equal length of the three-phase magnetic circuit, further improving the parameters, and having a regular triangular arrangement of the body and compact structure. The product has the characteristics of high efficiency and energy saving, which can save a lot of power consumption and operating costs, and has significant social benefits. It is mainly used in 10kV power transmission and distribution system, and can be widely used in residential areas, commercial streets, industrial and mining enterprises and rural power and lighting, commercial centers, subways, airports, stations, industrial and mining enterprises, drilling and oil production platforms and other places.
