CABLE FITTINGS FOR CONNECTING A HIGH-VOLTAGE CABLE WITH A HIGH-VOLTAGE COMPONENT Russian patent published in 2019 - IPC H02G15/02 

FIELD: electrical engineering.

SUBSTANCE: high-voltage cable fittings, usually cable termination or cable gland contains rigid conical insulator coaxially with respect to some axis (A), electrically insulating, elastomeric leveling cone (20), corresponding to a rigid conical insulator along conic interface (30), and an axially aligned current circuit. Current circuit connects conductor (42) of cable (40) to high-voltage current output (43), which is located on top of the rigid conical insulator and which is provided for connection to the high-voltage component. Rigid conical insulator is designed as capacitor core (10) and contains several electrically conductive levels (13a, 13b, 13c) of the field alignment, which are located concentrically around the axis (A), and rigid polymer matrix (14) into which the field alignment layers are embedded. Section (41) of conductor (42) of the cable, from which insulation (44) of cable (40) is removed, extends from conical border (30) of the section to high-voltage current output (43) and forms an axially aligned current circuit and capacitor core (10) contains axially aligned cylindrical channel (11), in which section (41) is located with the isolation of the conductor of cable (42) and which passes two opposite frontal surfaces (12a, 12b) of capacitor core (10).

EFFECT: invention keeps the size of cable accessories small and allows the valve to move high rated continuous currents.
