CABLE FITTINGS FOR CONNECTING A HIGH-VOLTAGE CABLE WITH A HIGH-VOLTAGE COMPONENT OR OTHER HIGH-VOLTAGE CABLE Russian patent published in 2019 - IPC H02G15/72 

FIELD: electrical engineering.

SUBSTANCE: high-voltage cable fittings (30) contain the rigid central insulator (1), having the first conical outer surface (4), concentrically passing around the longitudinal axis (5); the elastomeric leveling element (6) having the first conical inner surface (7) corresponding to the mentioned first conical outer surface (4) along the border line (9); and the rigid element (11) configured to press the elastomeric leveling element (6) against the boundary (9) of the interface. Leveling element (6) is put with tension on the rigid central insulator (1). Rigid element (11) contains at least one section (17) of pressure increase, which allows to achieve the desired minimum pressure at the interface while maintaining a compact total diameter along the circumference around the longitudinal axis (5), causing in the assembled condition of the cable fittings (30) the additional axial tensile stress (23) in the sleeve section (19) of the leveling element (6) extending the first conical outer surface (4) of the rigid central insulator (1).

EFFECT: high-voltage cable fittings are proposed.
