Description
Technical field
The utility model relates to a kind of fire-proof and water-proof cable with aqueduct.
Background technology
Cable products, at building, carries important data in engineered safety system, the transformation task of image and other information.So in the choosing of cable, buying fire-proof and water-proof type cable should be removed, even if cable is after breaking out of fire, time enough can be had all data to be steam again before whole network paralysis, and they are transferred to safe place, the possibility that data run off is dropped to minimum, cable is arranged in moist place sometimes, so will ensure the coefficient of safety of cable for waterproof, even if water infilters, often cause cannot using of cable, even waste.
Utility model content
The purpose of this utility model is the deficiency existed for prior art; there is provided one to have fire-proof function, protect conductor not short circuit, the fire prevention cable of open circuit when burning in the short time; and normally can work in a humid environment, and the cable of inner ponding can be discharged.
The technical solution of the utility model is: a kind of fire-proof and water-proof cable with aqueduct, by conductor, be wrapped in the insulating barrier of conductor outside, water-ring, tensile elements, bumper post, restrictive coating, external sheath layer and aqueduct, described conductor takes the conjunction of many merchandisers skein silk to form, in each conductor is all wrapped in by insulating barrier, described insulating barrier is outside conductor, described water-ring is divided into upper and lower both sides, be respectively the stop water of the side near insulating barrier, the side of the mixed layer of close tensile elements and bumper post is hydrating structure, described tensile elements and described three bumper posts form one deck jointly, bumper post is built up between sheath and water-ring, other free time be partially filled tensile elements, described restrictive coating is outside tensile elements and bumper post mixed layer, it forms independently waterproof construction, described external sheath layer is the outermost layer of cable, with the double water-resistance structure of restrictive coating shape paired cable, described water-ring is provided with aqueduct, one end of described aqueduct is communicated with water-ring, the other end of described aqueduct is extended by water-ring outer layers, cross the tensile elements of cable, restrictive coating and external sheath layer, exposed outside cable, the outer end of described aqueduct is provided with dust plug.
Further, described conductor at least 3 is stranded forms.
Further, on the upside of described insulating barrier be hydrating structure.
Further, on the downside of described insulating barrier be stop water.
Further, its material of described bumper post is PP material.
Further, be the mixed layer that tensile elements and bumper post are formed outside described water-ring, the two cross-distribution.
Further, described tensile elements material is steel wire.
Further, the material of described sheath is high abrasion vinyl polymer material.
Further, the material of described oversheath is high abrasion, water preventing ability material.
Further, the material of described aqueduct is water preventing ability material.
The beneficial effects of the utility model are: cable has pliability, the fire resistive construction of mica tape insulating barrier, effectively protect conductor, conductor not short circuit at short notice can be effectively protected when breaking out of fire, can work on, improve the fire protecting performance of cable, Exterior cable has the dual waterproof construction of sheath and oversheath, ensure that cable can normally work under the operational environment of humidity, in inside, also the structure of water-ring is had, even if water has revealed, also can be pinned by water-ring, if there is ponding inner at cable for a long time, can potential safety hazard be there is in this, aqueduct can extract ponding out from the inner water-ring of cable, substantially increase the coefficient of safety of cable, ensure its useful life.
