A bite-resistant cable includes at least one core cable and a cover layer surrounding the at least one core cable. The cover layer contains a peppery agent and an algefacient. The content of the peppery agent is between 0.5 wt % and 5 wt % of the total weight of the cover layer. The content of the algefacient is between 0.5 wt % and 5 wt % of the total weight of the cover layer. Therefore, the service life of the cable can be extended and a stable power supply can be provided.

The subject of the invention is an adhesive tape, in particular a wrapping tape for bundling cables in automobiles. Said tape is provided with a tape-like carrier and with an adhesive coating applied to all or part of one or two sides of the carrier. The carrier is constructed merely of a planar structure layer on the basis of plastic fibres. According to the invention, the carrier requires a piercing force of more than 0.2 N/m.sup.2 mass per unit area of the carrier when pierced with a needle having a diameter of 0.14 mm to 0.16 mm.

Yarns for electrical conduction that comprise a composite of fibres composed of carbon nanotubes and/or of a multiplicity of graphene layers and have a specific porosity are already known. The yarns have an electrical insulation layer, which is produced by application of a polymer coating. The electrical insulation layer has to adhere to the yarn sufficiently well for the insulation not to detach even in the event of mechanical stress, for example deflection with a small bending radius. Furthermore, the electrical insulation layer should be as thin as possible in order to achieve a low thermal resistance. Additionally, the electrical insulation layer has to be elastic enough to be able to cope with any geometric changes in the non-rigid yarn without detaching. In the electric conductor according to the invention, the electrical insulation is improved. The invention provides for the outer fibres of the composite to be fluorinated in such a way that they form an electrical insulation layer (2) and for the fibres in an internal region (3) to be electrically conductive.

A cable includes: a core; a first insulating layer that has a property biased toward positive polarity or negative polarity in a triboelectric series and coats the core; an (n+1)-th insulating layer that has a property biased toward a polarity opposite to a polarity of an n-th insulating layer and coats the n-th insulating layer, N being a natural number not less than 2, n being 1, . . . , N1; a braid that coats the N-th insulating layer; and a sheath that coats the braid.

An item may include fabric or other materials formed from intertwined strands of material. The item may include circuitry that produces signals. The strands of material may include non-conductive strands and conductive strands. The conductive strands may carry the signals produced by the circuitry. Conductive strands may be insulated by insulating strands that have been wrapped around the conductive strands. Insulating strands may include strands of fusible material that softens when heated to the appropriate temperature. Fusible insulating strands may be interspersed with insulating strands of a different material. The fusible insulating strands may be heated such that the fusible material melts and fills gaps between the other insulating strands, thereby forming a watertight covering over the conductive strand. The fusible insulating strands may be used to insulate electrical connections between conductive strands and/or between electronic components and conductive strands.
