Oil-immersed transformer is a transformer that uses transformer oil as a cooling medium, utilizing the principle of electromagnetic induction to convert high-voltage current to low-voltage current, or vice versa. Its basic components include primary side (high voltage side), secondary side (low voltage side), core and insulating oil.

Its basic components include primary side (high voltage side), secondary side (low voltage side), core and insulating oil.
1. The transformer core is made of imported high-quality cold-rolled silicon steel sheet, which greatly reduces no-load loss and no-load current, and reduces noise.
2. The transformer is isolated from the air to prevent and slow down the deterioration of oil and insulation aging.
3. The transformer connection group adopts Dyn11 to reduce the influence of harmonics on the power grid and improve the quality of the power supply. 4. The transformer is a fully sealed structure, extending the service life, and free core maintenance.
5. The measured noise value is lower than the standard.
Oil-immersed transformer is a widely used transformer in power systems with the following advantages:
Excellent cooling performance: Oil-immersed transformer adopts oil as cooling medium, which can effectively take away the heat generated during the operation of the transformer and ensure the stability and safety of the equipment.
Good insulation performance: Transformer oil has good insulation performance, can provide effective electrical isolation, to ensure the safe operation of equipment.
Strong ability to withstand overload: Oil-immersed transformers can withstand large loads in a short period of time and have strong overload capacity.
Long operating life: Due to its design and material selection, oil-immersed transformers usually have a long service life and low failure rate.
Large capacity adaptability: Oil-immersed transformers can be manufactured to large capacities, suitable for high power transmission and distribution.
Economy: In large-scale power facilities, oil-immersed transformers have relatively low investment and operating costs, with obvious economic benefits.
Power transmission and distribution system: Used in substations and distribution networks, responsible for the conversion and transmission of electric energy.
Industrial applications: Used in large industrial enterprises, such as metallurgy, chemical industry, mining industry, etc., when the demand for electricity is large.
High-rise buildings and large commercial complexes: Provide stable power supply for high-rise buildings and large commercial facilities.
Wind and solar power stations: In renewable energy power generation systems, the power generated is boosted and transmitted to the power grid.
Railroad and subway systems: To provide the necessary power supply support for rail transportation to ensure safe operation.
Overall, oil-immersed transformers play an important role in the power industry with their superior performance and wide applicability.
