In order to overcome the shortcomings of that existing lift car monitor video signal transmission technology is present, this utility model is provided Elevator trailing photoelectricity compound cable.

This utility model solves the technical scheme that its technical problem adopted：Elevator trailing photoelectricity compound cable, including Butterfly optical cable, knitted conductor, insulating barrier, tensile steel wire and flexible sheath, butterfly optical cable, tensile steel wire and establishment conductor are placed in bullet Property protective case in, establishment conductor outside be also enclosed with insulating barrier, butterfly optical cable is by aramid fiber traction-resistant fibre, the insensitive single mode of bending loss Optical fiber and pvc sheath are constituted, and aramid fiber traction-resistant fibre and bending loss insensitive single-mode fiber are placed in pvc sheath Interior, aramid fiber traction-resistant fibre is respectively placed in bending loss insensitive single-mode fiber two ends, and pvc sheath cross section is butterfly, is compiled Knit the bidirectional crossed braiding of oxygen-free copper-wire share split that conductor is more than to form, its cross section is flat, and insulating barrier is polyethylene Material, tensile steel wire is formed by the seizing wire of more than is stranded, and flexible sheath adopts rubber and plastic composite elastic material.

According to another embodiment of the present utility model, further include tensile steel wire it is stranded after external diameter be 1.0mm.

According to another embodiment of the present utility model, further include that knitted conductor is by 144 line diameters The bidirectional crossed braiding of 24 bursts of the oxygen-free copper-wire of 0.09mm point is formed.

According to another embodiment of the present utility model, further include that tensile steel wire is 0.20mm by 19 line diameters Zinc-coated wire stranded form.

According to another embodiment of the present utility model, the thickness for further including the upper and lower thinnest part of flexible sheath is not less than 0.8 ㎜, the thinnest part thickness on the outside of tensile steel wire is not less than 1.2mm.

The beneficial effects of the utility model are, this utility model has outstanding resistance to bend(ing) energy and tensile property, and It is small volume, easy to process, provide power supply and optical signal transmission function for elevator monitoring equipment.
