Product Description

Liu Gao is a 15KV Fully Sealed Oil Immersed Power Distribution Transformer Suppliers, our oil immersed transformers 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 oil-immersed transformer is reduced, and as the transformer oil doesn't contract with air, the oil ageing is retarded, thus prolonging the service life of oil-immersed transformer.

This product is 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.

15KV Fully Sealed Oil Immersed Power Distribution Transformer Operating Environment

1. Highest ambient temperature: +40℃

2. Lowest ambient temperature: -25℃

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.

15KV Fully Sealed Oil Immersed Power Distribution Transformer Characteristics

1. The oil-immersed transformer exhibits good heat emission and a substantial overload capacity. It can operate without a wind machine for an extended period at 130% overload, maintaining full load without compulsory wind cooling under IP45 conditions.

2. The oil-immersed transformer ensures perfect safety and resistance to fire, capable of withstanding combustion for a prolonged period at 800ºC without emitting smoke.

3. With strong resistance to thermal shock, the oil-immersed transformer can be loaded immediately at -50ºC.

4. The oil-immersed transformer features complete waterproofing and airproofing to enhance its durability.

5. Ensuring no partial discharge, the oil-immersed transformer maintains a high level of operational integrity.

6. With good hydrophobicity and resistance to alkaline cauterization and fundamental influence, the oil-immersed transformer proves to be reliable in diverse environmental conditions.

7. The oil-immersed transformer is environmentally friendly, producing low noise, no deleterious gases, and is easy to decompose.
