Abstract (en)
[origin: EP1528576A2] An electrical insulator (1) includes a shed (31) having a diameter larger than the shed diameter of the electrical insulator (1) in an upper portion of the electrical insulator (1), and the shed (31) has an elliptical or oval cross section. Accordingly, the airflow in the vertical direction of the electrical insulator (1) is reduced, and therefore the noise caused by pressure fluctuation on a shed of the electrical insulator (1) due to vortices generated at positions downstream of a structural component, such as a collector shoe, placed on top of the electrical insulator (1) is reduced.
