Overview
The SH15 is an oil-filled, hermetically sealed transformer that operates on the same principle as a sealed oil-immersed power transformer, with a core made of amorphous alloy. Amorphous alloy is composed of iron, nickel, cobalt, silicon, boron, carbon and other elements. It is an isotropic soft magnetic material with low magnetising power and no structural defects that impede domain-wall movement. The strip is extremely thin, only 0.027 mm, so the stacking factor is correspondingly lower, only 0.75–0.8. Its resistivity is very high, 3 to 6 times that of silicon steel sheet, and its hardness is 5 times that of silicon steel sheet; the material is particularly sensitive to mechanical stress.
For the SH15-M-30~2500/6~10 series, the no-load loss is 70% lower than the reference values of GB/T 6451. The product is manufactured to GB/T 25446-2010 'Technical parameters and requirements for oil-immersed amorphous alloy core distribution transformers'.
