Abstract
The utility model discloses a novel two-core insulating armoured anti-flaming cable, comprising two insulated wire cores. The insulated wire core is formed by a conductor and an insulating layer extruded out of the conductor. The two insulated wire cores are extruded and connected with an insulating layer through a plastic connector, so as to form a cable core. Gaps of the cable core are provided with a filler layer. A copper wire armor layer is woven out of the cable core. The outer sheath is extruded on the outermost layer. The filler layer in the cable is made of an inorganic material. The structure has very good fireproof thermal barrier effect in fire hazard, so the insulating layer of the cable is softened and is not melted in fire hazard. Then the metal armor layer is used, and the metal armor layer has effect of bearing external forces, and has effect of stabilizing a fireproof structure in the cable. Even through the cable is impacted in operation and installation, the material of the filler layer would not disperse, thereby ensuring reliability of the cable.
Description
Technical field
The utility model relates to a kind of power cable, specifically a kind of novel two core insulation armored flame-retardant cables.
Background technology
Flame resistant cable refers to the cable that can keep certain hour safe operation in flame combustion situation.China's standard GB/T 12666.6 is divided A, two kinds of ranks of B by fire resistance test, and 950 ~ 1000 ℃ of A level flame temperatures continue for fire time 90min, 750 ~ 800 ℃ of B level flame temperatures, continue for fire times 90 min, whole duration of test, sample should bear the load voltage value of product regulation.
Flame resistant cable is widely used in skyscraper, underground railway, undergrond street, large-scale power station and the important places relevant with fire safety and fire-extinguishing and lifesaving such as industrial and mining enterprises.The wrapped mica in existing flame resistant cable employing conductor outside brings and reaches fire-resistant effect, but cable install and work in often follow various collisions of rocking with junk, may make mica tape flame retardant coating become lax, even dissipate, cause cable to lose original flame-retardant function.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of good flame resistance, good insulating, the novel two core insulation armored flame-retardant cables that simple in structure, production cost is low.
A kind of novel two core insulation armored flame-retardant cables described in the utility model, comprise two insulated wire cores, and described insulated wire cores consists of conductor and the insulating barrier that is extruded in outside conductor; Between two insulated wire cores, by plastic connecting body and insulating barrier, jointly extrude and link together, form cable core; The gap of cable core is provided with packed layer, and cable core weaves copper wire armored layer outward, and outermost layer extrudes oversheath.
As improvement, described packed layer forms by inorganic material is wrapped.
Further improve, described insulating barrier adopts cross-linking polyethylene materials.
Further improve, described plastic connecting body adopts cross-linking polyethylene materials.
Further improve, described oversheath adopts polyolefine material again.
The utility model beneficial effect is:
Packed layer in the utility model is made by inorganic material, and this structure can play good flame retardant effect in fire, makes the insulating barrier of cable in fire, be softened and not melt.Adopt afterwards armour, except bearing External Force Acting, also play fire resistive construction in firm cable and the effect of fire insulation, even impacted in work with in installing, also can not cause loose the holding of material of packed layer, guaranteed the reliability of cable.In addition, changed the structure of reason cable core, do not re-used stranded mode, the utility model adopts plastic fastening that the insulating barrier of insulated wire cores is linked together, and forms cable core, has guaranteed the globality of cable core.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of novel two core insulation armored flame-retardant cables described in the utility model, comprise two insulated wire cores, and described insulated wire cores consists of conductor 1 and the insulating barrier 2 that is extruded in outside conductor 1; Between two insulated wire cores, by plastic connecting body 3 and insulating barrier 2, jointly extrude and link together, form cable core; The gap of cable core is provided with packed layer 6, and cable core weaves copper wire armored layer 4 outward, and outermost layer extrudes oversheath 5.
To sum up, described packed layer 3 is made by rope form inorganic material; Described insulating barrier 2 adopts cross-linking polyethylene materials; Described plastic connecting body adopts cross-linking polyethylene materials; Described oversheath 6 adopts polyolefine material.
The utility model provides a kind of novel two core insulation armored flame-retardant cable version and implementation methods; the above is only preferred implementation method of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvement, these improvement also should be considered as protection range of the present utility model.
