Abstract
The utility model discloses an insulating fire -resistant waterproof cable, including cable core, interior bed course, restrictive coating, this cable center is provided with fire -retardant layer, fire -retardant in situ portion fills there is flameresistant material, the fire -retardant layer outside is provided with the cable core, the cable core comprises cable conductor, insulating layer from the inside to surface in proper order, the cable core outside has set gradually interior bed course, steel band layer, restrictive coating, shielding layer, flame retardant coating, still be provided with the filling layer between insulating layer and the interior bed course. The utility model has the advantages of simple and reasonable structure, it is convenient to make, and insulating properties is strong, and the fire resistance is strong, and along the cable rate of propagation, waterproof nature is strong in the time of effectively reducing the flame burning.
Description
Technical field
The utility model relates to field of cable technology, is specifically related to a kind of insulated fireproof water-proof cable.
Background technology
At present, along with the development of society, power consumption also increases thereupon, require that the current capacity of cable is increasing, the conductor wire core cross section of cable constantly increases, and the unit weight of cable increases thereupon, existing cable easily spoils oversheath when laying, and leaves potential safety hazard; During fire, flame can spread along cable, a large amount of smog and poisonous corrosive gas can be produced simultaneously, harm is produced to human body, simultaneously, because cable is provided with joining seam at a place of connecing, insulated conductor has opening, so general insulated aluminum wire does not block water, due to the infiltration of rainwater, easily occur that sag corrodes, even cause the adverse consequences broken.
Utility model content
For overcoming above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide simple and reasonable, and insulation property are strong, fire resistance is strong, when effectively can reduce flame combustion along cable rate of propagation, a kind of insulated fireproof water-proof cable that water resistance is strong.
For achieving the above object, the technical solution of the utility model is: a kind of insulated fireproof water-proof cable, comprise cable core, inner cushion layer, restrictive coating, this cable center position is provided with flame-retardant layer, described flame-retardant layer inside is filled with fire proofing, described flame-retardant layer arranged outside has cable core, described cable core is made up of cable conductor, insulating barrier from the inside to surface successively, be disposed with inner cushion layer, steel belt layer, restrictive coating, screen, flame retardant coating outside described cable core, between described insulating barrier and inner cushion layer, be also provided with packed layer.
Further, described inner cushion layer adopts polythene PE-90 material to make.
Further, the thickness of described inner cushion layer is more than or equal to 3mm.
Further, described restrictive coating adopts pvc material to make.
Further, the thickness of described restrictive coating is more than or equal to 5mm.
Further, described cable core is any one in single core, twin-core, three cores, four-core, five cores, six cores, seven cores.
The utility model adopts the beneficial effect of technique scheme to be: the utility model is simple and reasonable, and it is convenient to manufacture, and insulation property are strong, and fire resistance is strong, and along cable rate of propagation when effectively can reduce flame combustion, water proofing property is strong.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described, but does not form any restriction of the present utility model.
As shown in Figure 1, a kind of insulated fireproof water-proof cable, comprise cable core, inner cushion layer 1, restrictive coating 2, it is characterized in that: this cable center position is provided with flame-retardant layer 3, described flame-retardant layer 3 inside is filled with fire proofing 4, described flame-retardant layer 3 arranged outside has cable core, described cable core is made up of cable conductor 5, insulating barrier 6 from the inside to surface successively, be disposed with inner cushion layer 1, steel belt layer 7, restrictive coating 2, screen 8, flame retardant coating 9 outside described cable core, between described insulating barrier 6 and inner cushion layer 1, be also provided with packed layer 10.
In the present embodiment, described inner cushion layer 1 adopts polythene PE-90 material to make, and the thickness of described inner cushion layer 1 is set to 3mm.
In the present embodiment, described restrictive coating 2 adopts pvc material to make, and the thickness of described restrictive coating 2 is set to 5mm.
In the present embodiment, described cable core is for being set to six cores.
The utility model is simple and reasonable, and it is convenient to manufacture, and insulation property are strong, and fire resistance is strong, and along cable rate of propagation when effectively can reduce flame combustion, water proofing property is strong.
More than show and describe general principle of the present utility model and principal character.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
