Utility model content
In view of this, it is simple that the utility model is intended to propose a kind of structure, and while realizing delivery of electrical energy, realize the high-power frequency conversion optical fibre composite electric power transmission cable of the all-fiber of Signal transmissions: comprise cable core, gasket for packing, total mask tape and oversheath; Described cable core is made up of three phase lines, three ground wires and fiber unit, the circle center line connecting of described three phase lines and the circle center line connecting of three ground wires form equilateral triangle respectively, and the center superposition of described two equilateral triangles, described fiber unit is positioned at the center of equilateral triangle; Described phase line is made up of phase conductor, crosslinked polyetylene insulated band, phase line mask tape and vinyl tape from inside to outside successively; Described ground wire is made up of wire core conductor and wire core insulating tape from inside to outside successively; Described cable core is surrounded by total mask tape and oversheath outward successively, is provided with gasket for packing between cable core and total mask tape.
Further, described phase line mask tape is that copper wire is dredged around phase-splitting shielding construction.
Further, described total mask tape is that copper wire is dredged around the wrapped total shielding construction of reverse copper strips.
Further, the material of described oversheath adopts environment friendly non-halogen low cigarette polyolefin macromolecular material.
Relative to prior art, phase line described in the utility model and ground wire adopt " 3+3 " centrosymmetric structure to combine, fiber unit is placed on symmetrical structure center, this structural design makes cable core structure more stable, farthest can reduce the harmonic voltage level that high order harmonic component produces, improve system security level, there is good antijamming capability; And the mask tape structure that the utility model adopts, can ensure environmental radiation interference low; In addition; the utility model is simply rational in infrastructure, while realizing delivery of electrical energy, realizes the all-fiber of Signal transmissions; drive singal can be improved, the transmission speed of signal of communication and accuracy between guard signal and each several part, be a kind of desirable big-power transducer coupling private cable.
