Oil Immersed Transformer

The transformer is completely hermetical oil-immersed type. The principle is the same as the hermetical power transformer. The basic elements of the amorphous alloy is Iron, nickel, cobalt, boron and carbon etc.

Product Description

The transformer is completely hermetical oil-immersed type. The principle is the same asthe hermetical power transformer. The basic elements of the amorphous alloy is Iron, nickel, cobalt, boron and carbon etc. It is a kind of isotropic soft magnetic material with low magnetizing power. With 0.027mm thickness and the filling coefficient is reduced to 0.75-0.8, the amorphous alloy material is very sensitive for stress. The electrical resistivity of the material is 3-6 times of silicon steel sheet and the hardness is 5 times of it.

Load loss of S(B)H15-M 30~1600/6~10 series transformer can be reduced by 15% on the basis of GB/T6451 standard. The no-load loss can be reduced by 70% on the base of GB/T6451 standard. Amorphous alloy transformer meets the standard JB/T10318-2002 Technical parameter of oil immersed type amorphous alloy transformer.
