Method for producing a cable core, having a conductor surrounded by an insulation, for a cable, in particular for an induction cable, and cable core and cable

A method for producing a cable, which comprises the steps of:

• producing a plurality of cable cores, each of the cable cores being produced by the further steps of:
• feeding a crude core continuously to a processing machine and there, recurrently, at predefined length positions the crude core is separated at a separation point, so that at the separation point two core ends exist, said crude core haying an insulation surrounding a conductor;
• pulling apart the core ends in a cable longitudinal direction;
• and
• reconnecting the two core ends with a connector, the connector having an insulating spacer part for separating the core ends from each other by a predefined distance, the core ends in the cable longitudinal direction fastened on both sides of the insulating spacer part to the connector, the insulating spacer part being disposed between the core ends and separating the core ends from each other by the predefined distance, the connector being integrally connected to the insulation and the insulation haying a first width and a first length, the connector haying a second width being greater than the first width of the insulation and a second length being less than the first length of the insulation;
• stranding together the plurality of cable cores resulting in stranded cable cores;
• and
• surrounding the stranded cable cores with a cable sheath to form the cable.
