| Zusammenfassung: | The present invention relates to a device for controlling an electric field at, for example, a connection, a termination, or a joint (1) of a high-voltage cable (2). The essential feature in the invention is a combination of capacitive field control (14), comprising a plurality of capacitive layers (15) arranged substantially concentrically between an inner live conductor (13) and an outer ground potential, and geometrical field control, comprising a stress cone (10) which is arranged in contact with said ground potential. |
