For solving the problems of the technologies described above, the embodiment of the present application provides a kind of novel compatibilized type water proof fire retardant cable, it is characterized in that: comprise and be arranged on the inside and outside cable core of wire packing and coating layer, described cable core is followed successively by cable conductor, internal shield, insulating barrier and outer shielding layer from inside to outside, and described coating layer is followed successively by glue layer, inner sheath, belting layer and oversheath from inside to outside.
As the preferred embodiment of this programme, described gasket for packing employing is non-opens net polypropylene tearing material.
As the preferred embodiment of this programme, described coating layer is connected with gasket for packing by glue layer, and coating layer is wound on the outer surface of gasket for packing in the shape of a spiral, and forms multiple spiral coil, forms overlapping portion between any two adjacent spiral coils.
As the preferred embodiment of this programme, described inner sheath adopts polythene PE-90 material extruding technique polar liquid, and standard design thickness is more than or equal to 2.5mm.
As the preferred embodiment of this programme, described oversheath adopts elasticity and flexibility pvc material all preferably.
As the preferred embodiment of this programme, described surface of outer sheath is provided with several semicircular arc groove circles, is provided with the depressed part being convenient to tear stripping in groove circle.
As the preferred embodiment of this programme, described glue layer is silicone based adhesive phase.
The one or more technical schemes provided in the embodiment of the present application, at least have following technique effect or advantage:
The construction of cable is simple, and it is convenient to manufacture, and its resistance to wear, water proofing property and anti-flammability improve greatly, when just not using hand strip off coating layer by when instrument, can not produce the situation of cutting off conductor, conveniently make cable end.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

In figure, 1, oversheath, 2, belting layer, 3, inner sheath, 4, glue layer, 5, wire packing, 6, outer shielding layer, 7, insulating barrier, 8, internal shield, 9, cable conductor.
Embodiment
In order to better understand technique scheme, below in conjunction with Figure of description and concrete execution mode, technique scheme is described in detail.
Embodiment one:
In embodiment one, as shown in Figure 1, a kind of novel compatibilized type water proof fire retardant cable, comprise and be arranged on the inside and outside cable core of wire packing 5 and coating layer, described cable core is followed successively by cable conductor 9, internal shield 8, insulating barrier 7 and outer shielding layer 6 from inside to outside, and described coating layer is followed successively by glue layer 4, inner sheath 3, belting layer 2 and oversheath 1 from inside to outside.
Wherein, in actual applications, described gasket for packing 5 adopts non-ly opens net polypropylene tearing material, the heat absorption capacity coefficient of material can be reduced, particularly on the filler cells basis of original limit gap, increase center-filled construction unit, press structure by densification and reduce construction of cable part thermal resistivity, cable dissipate heat effect is increased, effectively can prevent the overheated burning of cable.
Wherein, in actual applications, described coating layer is connected with gasket for packing 5 by glue layer 4, coating layer is wound on the outer surface of gasket for packing 5 in the shape of a spiral, and forming multiple spiral coil, form overlapping portion between any two adjacent spiral coils, making between two adjacent spiral coils can close contact, improve the sealing between spiral coil, preventing spiral coil slippage from making, conductor is exposed out causes potential safety hazard.
Wherein, in actual applications, described inner sheath 3 adopts polythene PE-90 material extruding technique polar liquid, and standard design thickness is more than or equal to 2.5mm, greatly reduces the transmitance of steam.
Wherein, in actual applications, described oversheath 1 adopts elasticity and flexibility pvc material all preferably, select low smoke and low halogen type polyvinyl chloride, and its oxygen index is greater than 35.The chlorination hydrogen amount generated during the burning of this low smoke and low halogen type polyvinyl chloride is only 1/5 of common flame-proof polyvinyl chloride, significantly can reduce the corrosion of organ stimulating to people and equipment.
Wherein, in actual applications, described oversheath 1 surface is provided with several semicircular arc groove circles, the depressed part being convenient to tear stripping is provided with in groove circle, when needs make cable end, stripping coating layer can be torn from the termination of coating layer, make conductor exposed to certain length, unnecessary coating layer can tear and also still can be wound on conductor outside surfaces, so when making cable end, when just can not hand strip off coating layer be used by when instrument, the situation of cutting off conductor can not be produced, conveniently make cable end.
Wherein, in actual applications, described glue layer 4 is silicone based adhesive phase,, this adhesive has good waterproof effect, when cable is dipped in water, block water can enter in coating layer and prevent cable short circuit, after coating layer strip off, still can coating layer be adhered on conductor, reusable.
Technical scheme in above-mentioned the embodiment of the present application, at least there is following technique effect or advantage: the construction of cable is simple, it is convenient to manufacture, its resistance to wear, water proofing property and anti-flammability improve greatly, when just can not hand strip off coating layer be used by when instrument, the situation of cutting off conductor can not be produced, conveniently make cable end.
Although described preferred embodiment of the present utility model, those skilled in the art once obtain the basic creative concept of cicada, then can make other change and amendment to these embodiments.So claims are intended to be interpreted as comprising preferred embodiment and falling into all changes and the amendment of the utility model scope.
