The S11 oil immersed hermetically sealed type transformer, as an upgraded version of the S9 series, achieves an average 20% reduction in no-load losses and 15% lower load losses compared to the S9. Utilizing high-permeability silicon steel sheets and a foil winding structure, it enhances short-circuit resistance by 30% and reduces operational noise by 5dB relative to the S9. This design innovation ensures compliance with stricter energy efficiency standards while delivering superior performance in demanding power distribution applications.

1. Comparison of the series transformer and S9 transformer, no-Load Loss is reduced by an average of about 30%.

2. We adopt structure of canister type or helix type at capacity rang 630kv to 2000kv for Low voltage coil; they are high machine intensity, balance distribution, good capacity of anti-short circuit.

3. We add a orientation structure, which make it don' t occur to move in the transport; accordingly add a nut in the product which makes sure the part don't fall down in function.

4. Spurting the varnish on the product after getting rig of the rust and oil mark, which make the product can used in special environment.

5. The ripple gasoline rank instead of oil cabinet, sealing the cabinet cover with cabinet edge, which extends the oil service life.
