Claims15
An electrical cable with self-repairing protection comprising:
- at least one conductor;
- at least one outer coating sheath;
- at least one layer of self-repairing material interposed between the conductor and the outer coating sheath, the self-repairing material layer being distributed around the conductor and having at least one region wherein its extension is interrupted, the self-repairing material being dielectric and having a predetermined cohesiveness and a controlled flowability at a working temperature of the cable;
- and
- at least one anchoring portion between the conductor and the outer coating sheath disposed at said interruption region.
