The transformer core is coiled with amorphous alloy strip, and the no-load loss is about 70% lower than that of S9 type transformer.

Copper foil coils are used at low voltage to enhance the transformer's ability to withstand short circuit.

Dynll is adopted in transformer connection group to reduce the influence of harmonics on power grid and improve power supply quality.

The transformer adopts vacuum oiling, which can completely eliminate the bubble in the coil and ensure the stable insulation performance.
