Abstract: A cable core for a cable, in particular for an induction cable, contains multiple such cable cores which have a conductor that is interrupted in the longitudinal direction at specified longitudinal positions at multiple separation points, thereby forming two conductor ends. An insulating intermediate piece is provided for connecting the conductor ends, the conductor ends being arranged on both sides of the intermediate piece. The cable core is characterized in that the conductor and the intermediate piece are surrounded together by a continuous insulating jacket in order to form the cable core. In a preferred concept, a respective intermediate piece is to be arranged between two conductor ends by two adapter elements. In another preferred concept, a respective intermediate piece, in particular a ceramic intermediate piece, is to be connected directly to two conductor ends. A cable is formed from a plurality of such cable cores.
