As a professional high quality liu gao 33KV Oil Immersed Power Distribution Transformer manufacturer, you can rest assured to buy Oil Immersed Transformer from our factory and we will offer you the best after-sale service and timely delivery.

The performances of model Lugao S11-33KV series oil-immersed distribution transformes conform to Standards IEC. Its core is made of quality cold-rolled silicon sheet and is of a full-miter non-puncture structure and its coil is made of quality

oxygen-free copper.It adopts radiator oil tank of corrugated shteet type or expansion type.

As it doesn't need oil conservator, the height of transformer is reduced, and as the transformer oil doesn't contract with air, the oil ageing is retarded, thus prolonging the service life of transformer.

This oil-immersed transformers. widely used in urban power grid reconstruction, residential district, factory, high-rise building, mining factory, hotel, shopping mall, airport, railway, oil field, wharf, highway and other outdoor places.

33KV Oil Immersed Power Distribution Transformer Operating Environment

3. Elevation: below 1000 meters

4. Highest monthly average relative humidity: 90% (at 20℃)

5. Installation location: suitable for installation in areas free from fire or explosion hazards, significant pollution, chemical corrosion, or excessive vibration, whether indoors or outdoors.

33KV Oil Immersed Power Distribution Transformer Characteristics

1.The oil-immersed transformer core is constructed using high-grade, imported cold-rolled silicon steel sheets, significantly reducing both no-load losses and currents. This also ensures a tight core binding for enhanced compactness and reduced noise levels.

2. The high and low voltage windings are meticulously wound with oxygen-free copper. For oil-immersed transformers with capacities of 500KVA and below, a double-layer, four-helix structure is employed for the low-voltage winding, while the high-voltage winding adopts a multi-layered cylinder configuration.

3. The oil-immersed transformer 's winding connections adhere to the Dyn11 standard, effectively minimizing the impact of harmonic waves on the power grid and enhancing overall power supply quality.

4. The oil-immersed transformer is designed with a fully-sealed structure, extending its operational lifespan and eliminating the need for suspended core usage and maintenance.

6. The measured noise level falls below established standards, ensuring a quieter and more efficient operation
