Insulation: Transformer bushings serve as insulating components, isolating and protecting the internal windings (coils) and the windings from the transformer's metallic casing or enclosure. This insulation is crucial in preventing current leakage or arc discharge, ensuring the safe operation of the transformer.

Mechanical Support: Bushings typically possess robust mechanical strength, capable of supporting the weight of the windings and withstanding external mechanical forces such as wind, rain, ice, and vibration. They also protect the internal windings from physical damage caused by the external environment.

Pollution Resistance: Transformer bushings often feature specially treated surfaces to enhance their resistance to pollution. This helps prevent the accumulation of contaminants on their surfaces, which could otherwise compromise their insulating properties.

Thermal Stability: Since transformers generate heat during operation, the materials used in bushings need to have good thermal stability to withstand high-temperature conditions without deterioration.
