Product Description

 

 

Product introduction
     The transformer can convert the voltage of the grid into the voltage required by the system or the load, and realize the transmission and distribution of electric energy. The transformer can replace the silicon steel sheet iron core transformer and is widely used in outdoor power distribution system. A large number of this product into the network operation can achieve good energy saving effect and can reduce the pollution to the atmosphere. This product is especially suitable for power shortage and load fluctuations and difficult to carry out daily maintenance areas. Because the transformer adopts a fully sealed structure, the insulating oil and the insulating medium are not polluted by the atmosphere, so it can operate in a humid environment, and it is the ideal distribution equipment in the vast distribution network in urban and rural areas.

 

Immersed amorphous alloy core distribution transformers(Pass the short-circiut test)

      Because the amorphous alloy iron core cannot withstand the action of mechanical force,and the mechanical strength of the rectangular coil is weak,the  short-circuit test of the amorphous alloy transformer 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 the SBH15-M-2500/10 distribution transformer by itself.Passed the short-  circuit test at the Shenyang National Transformer Quality Supervision and Inspection Center in one fell swoop,which marks that the company's amorphous alloy transformer design and manufacturing technology is at an advanced level
