A high-voltage conductor terminal, having screened insulation, comprises at least one insulation bush arranged at the end of the conductor in contact with the insulation of said conductor. A first screen envelopes the insulation of the conductor. A second or additional screen envelopes the end of the conductor, stretching beyond the butt end of the insulation bush, and is made as a portion coated with an electrically conductive material, which is in contact with the insulation of the conductor and connected to said conductor. The butt ends of the insulation bush are provided with annular toroid-shaped grooves each having screens made as portions coated with an electrically conductive material. The screen of one of the annular grooves of the insulation bush is connected to the first screen of the insulation of the conductor, and the screen, facing the end of said conductor, of another of the annular grooves of the insulation bush is connected to the second or additional screen of the insulation of the conductor. The ratio of the minimum distance between the annular grooves to the thickness of the insulation of the conductor is selected within the limits of about 0.2 to 5, and the permittivities of the materials of the insulation bush and the insulation of the conductor are selected to be approximately equal.
