A device for controlling an electric field at a high voltage component includes an inner deflector electrically connected to live voltage component; a resistive layer adapted for field control, arranged along the high voltage component, and electrically connected to the live high voltage component and electrically connected to a grounded part, the resistive layer having a nonlinear current-voltage characteristics; an insulating layer extending but ending without reaching the end of the resistive layer; and a semi-conducting or conducting layer arranged on the insulating layer and extending towards the resistive layer and past the end of the insulating layer, thereby defining an outer triple point at the intersection of the resistive layer, the insulating layer, and the semi-conducting or conducting layer. The resistive layer has first, second, and third adjacent sections, wherein a portion of the first section extends below the inner deflector.

Device for electric field control

A cable termination device of the dry type, for terminating a high voltage cable, including an insulator housing with a first end and a second end and having a hollow interior, and which second end has an opening for insertion of a high voltage cable. The cable termination device further includes a stress controller device located inside the insulator housing and adapted to be mounted on a high voltage cable, an end cap located at the first end of the insulator housing and provided with an external electrical connection means, and an electrically insulating gel filling at least part of the hollow interior of the insulator housing and surrounding at least part of the stress controller device. Further, the stress controller device is provided with a first and a second deflector arrangement for controlling an electric field.
