Core

The core material is made of high-quality cold-rolled silicon steel sheet carefully laminated in full 45 diagonally.

Finished 15 MVA 24.94/4.16KV Transformer

Solution for harmonic influence:

1. Made of high-performance silicon steel sheet material and lower magnetic flux density design so as to withstand overvoltage and harmonic influence unsaturated.

2. Lower current density design and sufficient margin to make winding withstand additional temperature rise caused by harmonic.

3. Advanced insulation structure that can withstand a variety of over-load insulation impact.

4. Reaching up to maximum 27 phases for secondary winding in results a great reduction of the influence of the harmonic on the power grid and other equipment.

FAQ
