A cable core for a cable, in particular, for an induction cable that includes 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, and the conductor ends are arranged on both sides of the intermediate piece. 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 arranged between the two conductor ends by two adapter elements. In another preferred concept, a respective intermediate piece, in particular, a ceramic intermediate piece, is connected directly to two conductor ends. A cable is formed from a plurality of such cable cores.

Method for producing a cable core for a cable, in particular for an induction cable

A cable has an outer sheath made from fluoropolymer and a conductor core having several individual elements which are surrounded by an inner sheath which penetrates into an intermediate chamber between the individual elements. A heat resistant film is disposed between the inner sheath and the outer sheath and is formed of a metal layer and a support layer.

Cable

A cable, in particular an induction cable, extends in a longitudinal direction along a longitudinal axis and is provided for laying in a pipe. A laying aid is mounted on the cable. The laying aid is formed so that the cable can be rotated about the longitudinal axis during laying. The cable is laid by a method for laying the cable which extends in a longitudinal direction, in which the laying aid is provided and the cable is laid in the longitudinal direction. The cable is rotated about a longitudinal axis extending in the longitudinal direction during laying.

Cable, in particular induction cable, method for laying such a cable and laying aid

An induction cable contains a plurality of cable conductors each having a conductor strand surrounded by insulation. The conductor strand contains a plurality of conductor sections which are spaced apart in the longitudinal cable direction at resonance dividing points by insulating intermediate pieces. The induction cable furthermore has a coupling device on which a plurality of the conductor strands are separated forming coupling ends at coupling positions. The coupling ends are connected to each other via the coupling device. A simple providing and installing of the induction cable and a simple replacement of damaged cable parts is thus enabled.

Induction cable, coupling device, and method for producing an induction cable

A production method produces a cable core for an induction cable in a simple and simultaneously reliable manner. In the method, a raw conductor is fed continuously to a processing machine and separated in a recurring manner at specified length positions at a separating point so that there are two wire ends. The ends are then pulled apart from each other in the longitudinal direction of the cable and then connected again by a connector which has an insulating spacer which separates the wire ends from each other by a specified distance. The connector is preferably configured as an injection molded part, in particular using the online process. A plurality of such cable cores are connected to each other via a cabling process and then enclosed by a cable sleeve to produce the induction cable.

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 cable having an electrical conductor, a silicone sheath surrounding the conductor, and a separation layer between the conductor and the silicone sheath. Said cable is characterized in that the separation layer is made of a silicone material that is less adhesive to the conductor than the material of the silicone sheath. The invention further relates to a method for manufacturing a cable of said type.

Cable and method for the production thereof

A silicone article, such as a cable with a silicone outer jacket. Solid mica particles are introduced into the surface of the cable or other article. An intermediate product which has a silicone-type base material on the exterior is initially provided in a state that is not, or no more than partially, cross-linked. The solid material particles are subsequently pressed in, before the complete cross-linking takes place. The solid material particles are present only in the surface region.
