Amorphous Alloy Oil-Immersed Transformer

Overview: An amorphous alloy core is an option when no-load loss is a significant selection factor. The complete oil-immersed transformer still has to satisfy the electrical, thermal, mechanical and site requirements of the application.

Where this configuration is considered

This approach is worth evaluating in distribution networks where equipment remains energized for long periods, including periods of lower load. Its value depends on actual operating hours and a consistent comparison of offered loss values and price.

Information to define before quotation

Request guaranteed no-load loss and load loss at the offered rating, along with voltage ratio, impedance, sound level, dimensions, cooling arrangement and test reports. Compare life-cycle assumptions consistently with a conventional-core option.

International standards to review

Reference standards may include IEC 60076-1:2011, IEC 60076-11:2018 (for dry-type designs). The applicable editions, clauses, conformity evidence and test scope must be agreed for the final design and destination market. This page does not claim certification or guaranteed compliance for an unspecified product.
