SBH25 Amorphous Alloy Tridimensional Toroidal Core Oil-Immersed Transformer

The SBH25 combines two cutting-edge technologies: amorphous alloy core material (25μm ultra-thin strip, excellent magnetic permeability) and tridimensional toroidal structure. The result is a transformer with up to 80% lower no-load loss compared with conventional silicon steel products — the pinnacle of energy-saving distribution transformer technology.
