Amorphous Alloy Power Transformer

Product Specifications

Product Description

The amorphous alloy oil immersed type transformers adopted amorphous alloy to construct the transformer cores, able to save no load loss about 70% or more compared with silicon steel, no-load current decrease about 80%, this type is most ideal distribution transformer to achieve best energy saving result.

Features:

-          Isotropic soft magnetic material

-          Low unit iron loss

-          Thin sheet, about 0.03mm, low filling factor

-          High resistance rate, low eddy current loss

-          Production technology simplified, energy saving, no pollution, but easily fragile

-          Sensitive to mechanical stress, influence on the performance.

-          Cost some higher.

Our amorphous transformers had overcome above problem, successfully passed strict type test (including S.C. test) from Shenyang Transformer Test Lab, a state lab with world famous institutes.

Generally the normal working condition required: -25ºC ~ 45ºC, altitude not more than 1000m, if some necessary parts changed, the transformer can run in more ultimate conditions: i.e. -45ºC~50ºC, or 2000m altitude and etc.
