220c oil-immersed transformer windings paper covered aluminum wire
Oil-immersed transformer windings paper covered aluminum wire can be used to make dry-type transformers, oil-immersed transformers and reactor windings.
Oil-immersed transformers typically use paper-covered copper wire for their windings, rather than aluminum wire. The use of copper wire is preferred due to its higher conductivity, better mechanical strength, and lower resistance compared to aluminum wire. Copper is a widely used material for transformer windings because it offers efficient power transfer and has excellent thermal conductivity, allowing for effective heat dissipation.
The paper covering on the copper wire serves several purposes. It provides electrical insulation between the windings and the transformer core, preventing short circuits and ensuring proper functioning of the transformer. The paper also helps to withstand the high temperatures generated during transformer operation and protects the copper wire from direct contact with the insulating oil.

The insulating oil used in oil-immersed transformers acts as a coolant and electrical insulator. It helps to dissipate the heat generated by the transformer, ensuring that the windings and other components operate within their temperature limits. The oil also enhances the insulation properties of the paper covering on the windings, preventing electrical breakdown and improving the overall performance and reliability of the transformer.
While aluminum wire is sometimes used in other applications due to its lower cost and lighter weight, it is not commonly used in oil-immersed transformer windings. The specific requirements for electrical conductivity, mechanical strength, and thermal properties make copper wire with paper insulation the preferred choice in this context.
