Abstract
A high-voltage cable fitting with a rigid core insulator that has a first conical outer surface extending concentrically about a longitudinal axis. An elastomeric stress relief element has a first conical inner surface is designed for mating the first conical outer surface at an interface. A rigid member is provided for pressurizing the elastomeric stress relief element at the interface. The stress relief element is pressed onto the rigid core insulator. The rigid member has at least one pressure enhancing portion extending circumferential about the longitudinal axis for causing an additional axial expansion stress in a sleeve portion of the stress relief element extending along the first conical outer surface of the core insulator in an assembled state of the cable fitting.
