FIELD: electricity.
SUBSTANCE: invention relates to power transmission technologies. Technical result is achieved by the fact that the high-voltage bushing includes a conducting rod and an air cooling device. Conducting rod has an air channel inside, wherein the air channel includes an air inlet and an air outlet. Air cooling device includes at least one fan, wherein the fan is configured to dispense an air flow to blow said air flow into said air channel through said air inlet.
EFFECT: preventing the creation of high electrical, thermal, and mechanical stresses inside high-voltage equipment used to perform high-voltage power transmission, during its long-term operation under the influence of high voltage, high current and strong mechanical load.
