Oil-immersed amorphous alloy transformer S (B) H

The transformer can convert the grid voltage into the voltage required by the system or load, and realize the transmission and distribution of electric energy. This transformer can replace transformers with silicon steel sheet iron core and is widely used in outdoor power distribution systems. The large-scale network operation of this product can achieve good energy saving effect and reduce air pollution. This product is especially suitable for areas with insufficient power and large load fluctuations and difficult to perform daily maintenance. Since the transformer adopts a fully sealed structure, the insulating oil and insulating medium are not polluted by the atmosphere, so it can operate in humid environments. It is an ideal power distribution equipment in urban and rural distribution networks.

Product features

Energy-saving products, no-load losses are about 75 lower than those of S9 transformers.
● Low loss, less heat generation, low temperature rise, stable operation;
● Advanced and reasonable structure, strong resistance to short circuit;
● Strong overload capacity, safe and reliable, strong corrosion resistance, maintenance-free.

10kV, 20kV oil-immersed amorphous alloy iron core distribution transformer (through short circuit test)

Due to the fact that the amorphous alloy core cannot withstand the action of mechanical force, and the mechanical strength of the rectangular coil is weak, the short-circuit test of amorphous alloy transformers has become a technical problem in the field of transformers. The company has successfully overcome this difficulty with mature technical experience and designed and developed SBH15-M-2500/10 distribution transformers by itself. The short-circuit test was passed in one fell swoop at the Shenyang National Transformer Quality Supervision and Inspection Center, which marks that the design and manufacturing technology of our amorphous alloy transformers is at the international leading level.
