This Oil Immersed Power Distribution Transformer 33kv having adopted the corrugated tank structure. It is a fully sealed, fully oiled, double windings, and no excited distribution transformer. This series product is A-class insulated, oil-immersed and self-cooled with tubular oil tank to be
installed outdoor, Its iron core is made of high quality oriented electrical steel, 45° obliquely jointed without punching and bond with
non-parellel in the world. Both of the inside and ourside winding are tightly bond on the hard paper rube, which makes is more fitful of the insulation. Temperature difference between winding and oil will be lower.

Our S11 lower loss series oil-immersed distribution transformers have reached modern advanced
level in the world.Transformers are used in the urban and rural power grid.
Features | Performance |
Core of transformer are made by the high quality cold-rolled grain-oriented silicon steel sheet with laser notch, inclined by 45°full-seam construction
| Reducing the load loss, load current and noise level |
HV winding is made by polyvinyl acetal wire enamel wire. | Reducing axial strength during short circuit happen |
Corrugate tank structure used in the transformer design | To ensure the quality of sealing |
The oil will be filling in the transformer under vacuum condition | Improved the insulation strength of transformer |
Oil level gauge with magnetic plate structure | It can fully isolation the oil tank and air, can ensure the quality of transformer oil not to effect by ultraviolet radiation |
