Abstract
An electric cable for communication purposes, for instance a one-pair party station cable which is designed as twin cable and includes a cross-section-wise relatively flat envelope or cover of thermoplastics or elastomers and includes conductors arranged in spaced relationship to each other and also includes traction relief members in about the middle between the conductors. The traction relief members are embedded in the envelope or cover and are adapted to exert the traction forces exerted on the cable in the longitudinal direction thereof. The traction relief members include high-strength fibers arranged symmetrically with regard to the longitudinal central plane of the cable and with regard to the conductors. The enveloping substance includes thermoplastics or elastomers.
Claims8
An electric cable for communication purposes having a flat oblong shape and comprising a plurality of conductors spaced from each other in the transverse direction of said cable, several traction relief means comprising in combination therewith several strength carrier means of high strength fibers arranged symmetrically with regard to the longitudinal central plane of said cable and with regard to said conductors, and an enveloping substance selected from the group consisting of thermoplastic and elastomeric material forming a common housing having said conductors and strength carrier means positively embedded and oriented substantially linearly therein, said carrier means, when viewing a cross section of said cable, comprising two pairs of carrier members spaced from each other in the direction of height of said cable, the carrier members of each pair being located on an imaginary straight line substantially parallel to an imaginary line interconnecting said conductors, and also being spaced from each other in the transverse direction of said cable.
