Amorphous Alloy Transformer Overview
Published three-phase references cover 30 to 3,000 kVA and 10 to 35 kV. Domestic product material states that no-load loss can be about 60% lower than a conventional oil-transformer reference; the exact comparison must use guaranteed values at the same rating.
The purchasing decision should compare total owning cost, guaranteed no-load and load losses, capitalization factors, sound level, footprint, short-circuit performance, tank structure, conductor, liquid, and the applicable S15, S21, or S25 series.
PRODUCT FITAmorphous Alloy Transformer: buyer-specific review points
For real procurement, Amorphous Alloy Transformer is judged by its project role, electrical boundary, verification documents, delivery condition, and the buyer's site limits before a factory quotation is compared.
Amorphous Alloy Transformer is mainly reviewed for Always-energized networks, Energy-efficiency programs, Renewable and industrial distribution. Amorphous-alloy oil-immersed transformers for distribution systems where energized hours and the cost of no-load losses justify a low-loss core design.
The first comparison should keep Phase: Three phase, Published capacity: 30-3,000 kVA, and Primary voltage: 10-35 kV visible so quotations remain technically comparable.
Published three-phase references cover 30 to 3,000 kVA and 10 to 35 kV. Domestic product material states that no-load loss can be about 60% lower than a conventional oil-transformer reference; the exact comparison must use. Confirm Core material: Amorphous-alloy wound core and Published series: S15 / S21 / S25 amorphous series before the data sheet is released.
For Amorphous Alloy Transformer, request documents such as Approved data sheet, GA and dimension drawing, Nameplate drawing, Routine test report, Inspection records. These files should match the ordered voltage class, rating, accessories, test plan, and nameplate.

Amorphous Alloy TransformerConfiguration decisions
Compare no-load and load losses at the same kVA, voltage, impedance, temperature basis, conductor, and tolerance instead of relying only on a percentage claim.
Apply project energy price, energized hours, loading curve, capitalization factor, discount period, maintenance, and purchase price to the total-owning-cost comparison.
Confirm amorphous core construction, flux density, clamping, sound-power requirement, mechanical robustness, short-circuit duty, transport handling, and installation vibration.
Identify S15, S21, or S25 series, approved loss table, efficiency statement, core material reference, routine report, relevant type-test evidence, and final nameplate.
Amorphous Alloy TransformerManufacturing and verification
Core, conductor, insulation, leads, and clamping are built to the approved drawing, with in-process dimensional and connection checks.
The tank, radiators, valves, bushings, and seals are assembled and leak checked. The active part is dried, and insulating fluid is filtered and vacuum filled according to the design.
Ratio, vector group or polarity, winding resistance, insulation, no-load and load losses, impedance, withstand, and leak tests are completed to the approved standard and order scope.
