Compared with a conventional grain-oriented electrical steel transformer of comparable rating and specification, the amorphous alloy core is primarily selected to reduce no-load loss. This makes the transformer suitable for systems that remain energized continuously or operate for long periods under light or variable loads.

Chinese-market configurations can be reviewed against the applicable requirements of GB 1094, GB/T 6451, GB/T 25446 and GB 20052.
Export configurations can be reviewed against IEC 60076 or another specified project standard. Final compliance depends on the approved design, guaranteed values and agreed test documentation.
Routine tests may include:
Type tests, special tests and third-party inspection can be agreed before production when required.
The operating-cost benefit of an amorphous alloy transformer depends on its guaranteed losses, load profile, annual operating hours and local electricity cost.
Selection should therefore be based on the approved no-load and load loss data rather than the series designation alone.
Please provide the rated capacity, voltage ratio, frequency, vector group, tapping range, guaranteed loss requirements, applicable standard, installation conditions, required accessories, quantity and destination.
