Power Transformer 2  S9 series

S9 series no-load loss is averagely 11% lower, load loss 28% and material cost exceeding 10%. The product is of low loss, low noise, high efficiency and energy saving.

The core is produced with high quality cold rolled silicon sheet steel, 45 degree all-slant no hole structure and glass-fiber band of high mechanical strength.

There are two types of winding. Cylingder-type and disc-type, for cylinder-type, HV, windings and LV, windings are wined spontaneously.

Short-circuit test shows the product has enough electrical and mechanical strength.

Corrugated tank: plate-bending ladder-shaped tank with fin-type radiator.
