Function of oil-immersed transformer bushings

Function of oil-immersed transformer bushings

1. Electrical insulation

Provide electrical isolation between high-voltage conductor and grounded metal parts to prevent current leakage and short-circuit accidents and ensure the safe operation of the transformer.

2. Mechanical support

Provide mechanical support for the conductor inside the transformer to ensure that the conductor remains stable during the operation of the transformer and is not affected by external vibration and impact.

3. Electrical connection

Allows high voltage conductors to be connected to external circuits through the transformer's tank, ensuring smooth and reliable power transmission.

4. Heat dissipation

Utilizes the thermal conductivity of transformer oil to help dissipate heat generated during transformer operation, preventing the transformer from overheating and ensuring its normal operating temperature.

5. Protection from environmental influences

The enclosure provides mechanical protection against external environmental influences (such as moisture, dirt and contaminants) on the internal electrical components, extending the life of the transformer.
