The inventive task is aimed at producing cable for field communication with a static friction force of insulation relative to a lay sufficient for the cable assembling.The cable comprises two copper-clad steel conductors with polyethylene sheath and pair twisted comprising steel and copper wires not twisted in a lay and arranged in parallel, each steel wire is corrugated (wavy shape) in one and more planes with sinusoidal, triangular or any other wave shape, the corrugated wires are in a bundle without an offset or with an offset longitudinally relative to each other to +/-(0...&pgr;), the corrugating planes of separate wires are oriented parallel or non-parallel, the copper wires are straight, the steel and copper wires are arranged at random or assembled in bundles laid in parallel in the conductor. Similar to the steel wires the copper wires can be corrugated, other orientation of corrugating planes and the wire offset relative each other. |
