The invention relates to a high-voltage bushing and high-voltage electrical equipment of using the same. A mean field section is set into a smooth shape, is relatively regular in shape and is free ofa protruding tip, so that the electric field intensity of an electric field at various positions on the mean field section is basically the same when the mean field section is in the electric field, and the maximum electric field intensity on a sleeve body is relatively reduced, thereby ensuring the insulating capacity of the high-voltage bushing, avoiding the flashover phenomenon of the high-voltage bushing and improving the security level of the high-voltage bushing.
