<p>A coaxial cable comprises a carrier cable (2) with a center conductor (4) which is filled with an insulator (5) and covered with an insulator (6), at least one induction cable (3) with an induction wire (7) covered with an insulator (8), and an outer conductor (9) covering the carrier cable (2) and the induction cable (3). To avoid unwanted piezoelectric effects induced in the dielectric substances subjected to possible physical pressure and to increase the induced output of the coaxial cable, the induction cable (3) is helically wound on the carrier cable (2). </p> |
