Abstract
Provided are devices, methods and systems. A cover system may include a unitary cold shrinkable, tubular, elastomeric cover sleeve defining a cover sleeve through passage that is configured to receive the electrical cable. The cover sleeve may include a first type of stress control element and a second type of stress control element that is different from the first type of stress control element. A holdout maintains the cover sleeve in an expanded state in which the cover sleeve is elastically expanded and when removed, permits the cover sleeve to radially contract to a contracted state about the electrical cable. The first type of stress control element includes a geometric stress cone that includes an electrically conductive and/or semiconductive portion that is configured to conductively engage a semiconductor layer of the electrical cable. The second type of stress control element includes a high-K stress relief element.
