What is the difference between a hexaformer and a transformer?

The hexa-transformer is a three-phase transformer with a specially shaped core, arranged in a triangular shape. The core consists of nine rolls of laminated steel bands and the core legs have a cross sectional shape of a hexagonal.

Transformers built according to this concept are characterised byhigher energy efficiency, lower weight and volume, lower vibrations and noise level, lower electromagnetic stray field, inrush current and lack of third harmonic.

In addition, compared to the traditional technology of power transformer production that involves a large amount of manual labour, the new technology allows automating the production process to a large extent.
