Abstract

A power cable (10) includes at least one electrical conductor (12) and at least one interstice (14) in the vicinity of the electrical conductor (12). The cable (10) further has at least one electronic device (18) for radiofrequency identification and at least one tube (16) arranged in the at least one interstice (14) and containing the electronic device (18) for radiofrequency identification.

First claim

The invention claimed is:

1 . A power cable comprising:
at least one electrical conductor and at least one interstice in the vicinity of said electrical conductor, said cable further comprising at least one electronic device for radiofrequency identification, wherein at least one tube arranged in said at least one interstice and containing said electronic device for radiofrequency identification, wherein said power cable further comprising at least one support cord arranged in said tube and freely mobile inside said tube, and wherein the length of said at least one support cord is greater, by less than 10%, than the length of said at least one tube.

2 . The cable according to claim 1 , wherein said at least one electronic device for radiofrequency identification is arranged on said at least one support cord.

3 . The cable according to claim 1 , wherein said tube has an inner diameter such that the area of the cross section of said electronic device for radiofrequency identification represents a third of the area of the inner cross section of said tube.

4 . The cable according to claim 1 , wherein said at least one tube has a smooth inner wall.

5 . The cable according to claim 4 , wherein said tube is made by extrusion.

6 . The cable according to claim 1 , further comprising a plurality of electrical conductors and a plurality of interstices between the conductors of said plurality of electrical conductors, wherein said cable further comprises a plurality of tubes arranged in said plurality of interstices, each of said tubes containing at least one electronic device for radiofrequency identification.

7 . The cable according to claim 1 , wherein said at least one electronic device for radiofrequency identification comprises at least one chip and at least one communication antenna.

8 . The cable according to claim 1 , wherein said cable is a mining cable.
