What is the current-carrying capacity of high voltage transformer bushings?

The current-carrying capacity of high voltage transformer bushings depends on their design, materials, and intended application. Typically, bushings are rated to carry high currents, sometimes up to thousands of amperes, depending on the transformer’s power rating. Exceeding this capacity can lead to overheating and insulation failure, so it’s essential to match the bushing’s capacity to the transformer’s operational requirements.
