Abstract (en)
[origin: US4751614A] In order to protect a cable, which can be laid in the soil and the conductors of which are electrically conductively connected with a plurality of electrical circuit units, which are arranged distributed at spacings along the cable in the interior of the cable core (2), which is surrounded by a sheath, which comprises a layer of high electrical conductivity and an outer layer for protection against chemical influences, reliably against electrical and magnetic disturbances coming from outside, the sheath additionally displays an inner layer of a material of high magnetic permeability. Beyond that, the outer layer can possess an electrical conductivity, the value of which lies between the conductivity values of the surrounding soil and the middle layer. In order to be able to produce such a cable as simply as possible, the circuit units are first electrically conductively connected with the conductors and then embedded together with these in the inner protective layer of the cable, for example by extruding-in.
