SBH15 Oil-immersed Amorphous Alloy Core Transformer

The product is fully-filled oil-sealed, with the same principle of sealed power transformers. The elements of amorphous alloy are iron, nickel, cobalt, boron and carbon. The material is isotropic and soft magnetic with low magnetization power. The structural defect that hinders the moving of domain walls with extremely thin thickness of merely 0.027 mm, merely small filled coefficient of 0.75 to 0.8, 3 to 6 times higher resistivity compared with silicon steel sheets, and 5 times hardness. Amorphous alloy is sensitive to stress.

The load loss of SBH15 series products drops 15% according to GB/T6451 standard whereas the no-load loss drops 75% to 80% according to GB/T standard. The products implement the JB/T10318-2002“Specification and technical requirements for oil-immersed amorphous alloy core distribution transformers”.
