Abstract: A high-voltage cable sealing end (100) has a primary volume (102) and a secondary volume (104) fluidically connected thereto, which are filled with an insulating fluid. The primary volume (102) and the secondary volume (104) are sealed with respect to the atmosphere surrounding the high-voltage cable sealing end (100). The secondary volume (104) can be disconnected from the primary volume (102) via a separable connection (106) which can be cut off in a fluid-tight manner. A drying agent, which draws moisture out of the insulating fluid, is introduced into the secondary volume (104).

Abstract: A device is provided for connecting two hybrid electrical transmission cables each having stranded first conductive wires made of a first metal in the central zone of the cable and second conductive wires that are made of a second metal of higher hardness than that of the first metal and wound on and outside this central zone, the second conductive wires of the cables being connected by an external conductive sleeve. The central first wires of the cables are connected by a weld made of the first metal and connecting their end, this weld and this end being covered by a tube of metal of hardness equal to or higher than that of the second wires, at least partially in line with the sleeve, the end of the second wires being re-formed on the first wires and on the tube under the external conductive sleeve.

Abstract: A three-phase, buried, high-voltage electrical line has three phase-conducting cables (2), each of the conducting cables (2) made of a succession of cable portions (3,3a,3b) connected together by different types of screen-break junctions (4), each junction (4) comprising a main structure (5) connecting a first portion (3a) to a second portion (3b) of cable (2). The main structure (5) of all the junctions (4) is identical and has a standard connection interface (7) connected to a first screen of the first portion (3a) and to a second screen of the second portion (3b), and in that a variable module (6,6a,6b,6c) furnished with a complementary connection interface (8) and with at least one linking cable (9,11,14,15), is capable of being plugged into the connection interface (7) of the main structure (5) of each junction (4).
