A 3D iron-core oil-immersed distribution transformer is a type of electrical transformer used in power distribution networks.

Advantages

· Efficiency: The use of an iron core and oil cooling improves the efficiency of the transformer by minimizing losses.

· Cooling and Insulation: Oil-immersed transformers have better cooling and insulation properties compared to dry-type transformers, making them suitable for higher voltage applications.

· Durability: The oil also helps in extending the lifespan of the transformer by protecting the internal components from environmental factors and electrical faults.

Applications

· Power Distribution: They are widely used in electrical distribution networks to step down the voltage from transmission levels to distribution levels, suitable for residential, commercial, and industrial use.

· Renewable Energy: These transformers are also used in renewable energy systems, such as wind and solar farms, to connect generation units to the grid.
