High voltage through-wall sleeve, as the name suggests, is the high voltage power through the wall, from indoor to outdoor or outdoor to indoor, or high voltage switch or transformer inside and outside through the shell wall for high voltage power guidance device.
When the conductor in the high-voltage through-wall bushing is not installed vertically, the short insulation distance will cause the discharge problem of the gas gap or the insulator surface supporting the conductor. The following is the solution.
A tension device is arranged in the high pressure wall penetrating sleeve, and the tension device is connected with the conductor. The tension provided by the stretching device is used to overcome the drooping of the conductor caused by its own gravity when it is not vertically installed, so that the conductor can be kept in a straight line as far as possible when it is not vertically installed, so as to avoid the gas gap or the discharge of the solid insulation surface caused by the shortening of the insulation distance between the conductor and the casing, and thus prevent the casing from being damaged. Improve the reliability of high pressure through-wall casing; At the same time, the tension device also enables the high pressure through-wall sleeve of the invention to cancel the insulating support of the conductor, so as to more effectively ensure the reliability of the high pressure through-wall sleeve.
