Design of Transformer Bushings

Transformer bushings are made to fulfil the transformer's electrical, mechanical, and thermal requirements. Choosing the right insulating material, figuring out the dimensions of the bushings, and creating the interface with the transformer tank and related electrical system are all parts of the design process. The following are the key aspects of the design of transformer bushings: Insulation Material: In addition to having a high dielectric strength, strong thermal conductivity, and resistance to ageing and moisture, the insulation material used for transformer bushings must also be fireproof. Oil-impregnated paper (OIP), resin-impregnated paper (RIP), and synthetic polymers like silicone rubber or epoxy are the most often utilised insulation materials. Voltage Rating: The highest voltage to which the transformer bushings will be exposed when in use determines the voltage rating of the bushings. The electrical and thermal stressors that affect the bushing, such as the electric f
