Abstract
The utility model discloses a double-sheath flame retardation tension cable comprising four insulation power wire cores, a flameproof filling rope, a silicone rubber inner sheath, a waterproof belt taped covering and a polyvinyl chloride oversheath; the insulation power wire core is formed by using an neoprene insulation layer and a glass fiber taped covering to extrude in sequence from outside-in on three tin-coated copper wire twisted conductors; the four insulation power wire cores are twisted to form a cable core; the cable core is wrapped in sequence from outside-in by the polyvinyl chloride oversheath, the waterproof belt taped covering, the silicone rubber inner sheath and the flameproof filling rope; the center of the cable core is provided with a liner layer having a tension steel wire. The cable is reasonable in structural design, uses a dual-sheath structure to increase anti-aging and anti-wearing property, is fireproof, waterproof, excellent in shielding performance, and stable in performance.
Description
Technical field
The utility model relates to cable, relates in particular to a kind of pair of shield sleeve flame tensile cable.
Background technology
The wider fire prevention cable of present stage application mainly contains UL fire-retardant cable and the large class of flame-retardant low-smoke halogen-free cable two.In imported product, mainly come from America and Europe, due to America and European fireproof cable standard incompatible, fire prevention thinking is very different, therefore, Party A and designing institute when selecting product all in passive state, each have their own reason, finally selects according to the actual conditions of fund often.Safety in order to ensure data, people just wish after breaking out of fire have time enough before whole network paralysis, all data to be steam again, and they are transferred to safe place, the possibility that data are run off drops to minimum, and fire-retardant fireproof cable is exactly very important guarantee.
Utility model content
According to above-mentioned situation, the utility model object is to provide a kind of pair of shield sleeve flame tensile cable.
Scheme of the present utility model is as follows: a kind of pair of shield sleeve flame tensile cable, it is comprised of insulated power core, fire-retardant gasket for packing, silicon rubber inner sheath, waterstop lapping layer and polyvinyl chloride oversheath, and described insulated power core ecto-entad is extruded on three tinned copper wire stranded conductors and forms with neoprene insulating barrier, glass fibre lapping layer successively; Four thoroughly do away with edge power core twisted synthesizing cable core; Described cable core is extruded with polyvinyl chloride oversheath, waterstop lapping layer, silicon rubber inner sheath and fire-retardant gasket for packing from outside to inside successively; Described cable core center is provided with inner covering; In described inner covering, be provided with tension steel wire.
Described inner covering adopts ceramic fluorubber material.
The beneficial effects of the utility model: the utility model reasonable in design, adopt two jacket structures, increase anti-aging and resistance to wear, and this cable has fire prevention, water-fast feature, shielding properties is good, the feature of stable performance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model,
Wherein: 1, insulated power core; 2, neoprene insulating barrier; 3, glass fibre lapping layer; 4, tinned copper wire stranded conductor; 5, fire-retardant gasket for packing; 6, silicon rubber inner sheath; 7, waterstop lapping layer; 8, polyvinyl chloride oversheath; 9, tension steel wire; 10, inner covering.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further;
As shown in Figure 1, a kind of pair of shield sleeve flame tensile cable, it is comprised of insulated power core 1, fire-retardant gasket for packing 5, silicon rubber inner sheath 6, waterstop lapping layer 7 and polyvinyl chloride oversheath 8, and described insulated power core 1 ecto-entad is extruded on three tinned copper wire stranded conductors 4 and forms with neoprene insulating barrier 2, glass fibre lapping layer 3 successively; Four thoroughly do away with edge power core 1 is twisted into cable core; Described cable core is extruded with polyvinyl chloride oversheath 8, waterstop lapping layer 7, silicon rubber inner sheath 6 and fire-retardant gasket for packing 5 from outside to inside successively; Described cable core center is provided with inner covering 10; In described inner covering 10, be provided with tension steel wire 9.
10 layers of employing ceramic fluorubber material of described liner.
Although above embodiment of the present utility model has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present utility model and change and revise; when its function producing does not exceed spiritual that specification contains yet, all should be within protection range of the present utility model.
