Transformer bushings are an essential component of electrical transformers, and their primary functions include the following: 

1. Insulation: Bushings serve as insulation for the electrical components of transformers. They isolate high-voltage windings (e.g., the high-voltage side) from ground or low-voltage windings, preventing electrical shock and arc faults and ensuring the safety and reliability of electrical power transmission.

2. Conduction: Bushings typically have conductive components used to connect transformer windings to external electrical systems. They transfer current from the transformer winding to other electrical equipment, such as switchgear or power lines, through wires or connectors at the top of the bushing.

3. Monitoring and Maintenance: Bushings often include equipment for monitoring and maintaining the transformer's condition. These devices help detect the transformer's operational status and identify potential faults or insulation issues in advance.

4. Protection and Sealing: Bushings also serve to protect the electrical components inside the transformer from contamination and damage by the external environment. They typically offer dust-proof and sealing capabilities, ensuring that the transformer's internal insulating oil or dry insulation system remains uncontaminated.

In summary, transformer bushings are a critical component of transformers used for insulation, conduction, monitoring, and protection, ensuring the safety and reliability of electrical power transmission.
