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

A termination for extra high voltage includes, around a central conductor (), a deflector cone () made of flexible material covered by a polymer insulator having a first internal insulating element () and containing a conducting deflector (), the conductor () is connected to an output terminal (). The maximum diameter (D) of the first insulating element () at right angles to the length (L) of the deflector cone () included between the conducting deflector () and the adjacent end of the output terminal () is greater than or equal to double the maximum diameter (d) of the conducting deflector ().
