Brief instruction:
SBH15 series Amorphous alloy Transformer is a low-loss, energy-efficient power transformer.
Such Transformers use iron-based amorphous metals as iron cores.
Since the material does not have a long-range ordered structure,
its magnetization and demagnetization are easier than general magnetic materials.
Therefore, the iron loss (i.e., empty load loss) of amorphous alloy Transformers is 70-80 % lower than that of
conventional Transformers that generally use Silicon steel as the core.
Advantages of Amorphous Metal Transformers (AMT):
Lower no-load loss. As the no-load loss is lower, the temperature rise of transformer is lower.
Better harmonic wave tolerances. Potential for lower total cost of ownership.
What is amorphous alloy transformer?
An amorphous metal transformer (AMT) is a type of energy efficient transformer found on electric grids.
The magnetic core of this transformer is made with a ferromagnetic amorphous metal.
Are amorphous core transformers more efficient?
Amorphous core transformers offer a 70 to 80% reduction in no-load losses compared to transformers
using CRGO core material for the same rating of Distribution Transformers.
What is amorphous alloy?
Amorphous alloys are a class of metallic materials that are not crystalline in nature as compared to most metals,
but demonstrate great properties such as high strengths (in the order of 1–2 GPa), high elastic strain
limits of up to 2%, good corrosion resistance, etc.,.
