Abstract
The invention provides a low-smoke zero-halogen environment-friendly fire resistant cable. The low-smoke zero-halogen environment-friendly fire resistant cable comprises a plurality of cable cores, wherein an outer sheath is arranged outside the cable cores after the cable cores are intertwisted to form the cable, each cable core comprises a conductor and a cross-linked polyethylene insulating layer, low-smoke zero-halogen filling fibers are arranged in gaps formed among the cable cores, and a ceramic silicone rubber fire resistant layer is arranged between the cable cores and the outer sheath. Due to the fact that degradable filling fibers are adopted in the cable, environmental pollution cannot be caused; due to the fact that the outer sheath is made of polyolefin materials, poisonous gas and dense smoke cannot be generated in the process of combustion of the cable, and the safety index is high.
Description
Technical field
The present invention relates to a kind of power cable, relate 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.
Summary of the invention
Technical problem to be solved by this invention 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 invention 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 a further improvement on the present invention, conductor is oxygen-free copper stranded conductor.
As a further improvement on the present invention, the thickness of silastic-layer is 6-8mm.
The beneficial effect that the present invention reaches: the invention 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, during cable fire, can not produce toxic gas and dense smoke, 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 invention will be further described.Following examples are only for technical scheme of the present invention is more clearly described, and can not limit the scope of the invention with this.
As shown in Figure 1, the invention 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 the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the technology of the present invention principle; can also make some improvement and distortion, these improvement and distortion also should be considered as protection scope of the present invention.
