A high-voltage cable fitting (30) with a rigid core insulator (1) that has a first conical outer surface (4) extending concentrically about a longitudinal axis (5). An elastomeric stress relief element (6) has a first conical inner surface (7) is designed for mating the first conical outer surface (4) at an interface (9). A rigid member (11) is provided for pressurizing the elastomeric stress relief element (6) at the interface (9). The stress relief element (6) is pressed onto the rigid core insulator (1). The rigid member (11) has at least one pressure enhancing portion (17) extending circumferential about the longitudinal axis (5) for causing an additional axial expansion stress (23) in a sleeve portion (19) of the stress relief element (6) extending along the first conical outer surface (4) of the core insulator (1) in an assembled state of the cable fitting (30).
