Abstract
The utility model provides a low-smoke halogen-free environment-friendly fireproof cable which comprises a plurality of wire cores which are stranded to be a cable. An outer sheath is arranged outside the cable. Each of the wire cores comprises a conductor and a cross-linked polyethylene insulating layer. The gap among the plurality of wire cores is provided with a low-smoke halogen-free filling fiber. A ceramic silicone rubber fireproof layer is arranged between the cable cores and the outer sheath. The degradable filling fiber is employed by the cable, no environmental pollution is generated, the outer sheath is a polyolefin material, no toxic gas and heavy smoke are generated in the burning of the cable, and the safety index of the cable is high.
Description
Technical field
The utility model relates to a kind of power cable, relates in particular to a kind of low smoke and zero halogen environmental protection fire-resisting cable.
Background technology
The filler of the core gap location of existing fire-resisting cable mostly is nondegradable polypropylene flame redardant gasket for packing, and sheath material mostly is polyvinyl chloride, produces toxic gas and dense smoke during cable fire, is easy to human body to damage.In addition, the flame retardant coating of existing fire-resisting cable needs wrapped and extrudes two procedures, and more loaded down with trivial details, production efficiency is low.
Utility model content
Technical problem to be solved in the utility model is to overcome defect of the prior art, and a kind of low smoke and zero halogen environmental protection fire-resisting cable is provided, and this cable has low smoke and zero halogen environmental protection characteristic and higher fire resistance.
For solving the problems of the technologies described above, the utility model provides a kind of low smoke and zero halogen environmental protection fire-resisting cable, comprise many cores, peripheral hardware oversheath after many core twisted synthesizing cables, core comprises conductor and crosslinked polyetylene insulated layer, gap location between many cores is provided with low smoke and zero halogen fiberfill fibers, is provided with the silicon rubber flame retardant coating of ceramic between cable core and oversheath, and silicon rubber flame retardant coating is disposable extruding and sulfidization molding.
As further improvement of the utility model, conductor is oxygen-free copper stranded conductor.
As further improvement of the utility model, the thickness of silastic-layer is 6-8mm.
The beneficial effect that the utility model reaches: the utility model provides a kind of low smoke and zero halogen environmental protection fire-resisting cable, cable adopts degradable fiberfill fibers, can not produce environmental pollution, oversheath is polyolefine material, can not produce toxic gas and dense smoke during cable fire, and safety index is high, the disposable of silastic-layer extruded and sulfidization molding, replace two procedures original wrapped and that extrude, saved the production time, improved efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of low smoke and zero halogen environmental protection fire-resisting cable.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection range of the present utility model with this.
As shown in Figure 1, the utility model provides a kind of low smoke and zero halogen environmental protection fire-resisting cable, comprise four cores, peripheral hardware oversheath 5 after four core twisted synthesizing cables, core comprises conductor 1 and crosslinked polyetylene insulated layer 2, gap location between four cores is provided with low smoke and zero halogen fiberfill fibers 3, is provided with the silicon rubber flame retardant coating 4 of ceramic between cable core and oversheath 5; Conductor 1 is oxygen-free copper stranded conductor, and the thickness of silicon rubber flame retardant coating 4 is 6-8mm.
The above is only preferred implementation 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 know-why; can also make some improvement and distortion, these improvement and distortion also should be considered as protection range of the present utility model.
