Abstract
A flame-retardant cable comprises insulating cable cores and an outer protective layer. A crosslinked polyethylene insulating layer is arranged outside a conductor in an extruded mode to form each insulating cable core; a lining layer is wrapped after the three insulating cable cores are combined, a fire-resistant mica layer is wrapped on the lining layer to form each conductor core; a fire-resistant mica layer II, a flame-retardant coating, a dual-layer flame-retardant wrapping tape layer and the outer protective layer are sequentially wrapped after the four conductor cores are combined; four control cable cores are arranged between the four conductor cores, and wrapping tape layers are wrapped on pair cable sets to form the control cable cores; an insulating cable core II is further arranged at the center of the combination of the four conductor cores, and the insulating cable cores with the crosslinked polyethylene insulating layers are arranged outside the conductors in an extruded mode to form the insulating cable core II. By means of the cable, flames can be effectively prevented from spreading to the insulating layers when the cable is on fire, and the good flame retardance is achieved.
Description
technical field
The present invention relates to a kind of flame retardant cable, belong to technical field of electric wires and cables.
background technology
Along with the development of shipping industry, especially along with the development of large-tonnage ships technology, also more and more for the cable demand of boats and ships.Along with scientific and technical development, to requiring also more and more higher with the cable of marine equipment.Conventionally flame retardant cable used is substantially all to adopt flame retardant insulation material, fire-retardant band, flame-retardant filler, flame-retardant sheath material.Its deficiency is: in the time of breaking out of fire, cable stops the performance of propagation of flame not strong, and flame easily spreads to insulating barrier.Boats and ships and personnel's safety is caused to very large hidden danger.For shipboard cable, fire resistance requires very high, and the cable of ordinary construction, in the time of ignition of cable, can not effectively stop spreading of flame.
summary of the invention
The object of the present invention is to provide a kind of flame retardant cable, in the time of ignition of cable, can effectively stop flame to spread to insulating barrier, fire resistance be good, and has stagnant right property.
The solution of the present invention is as follows: a kind of flame retardant cable, comprise insulated wire cores, external sheath layer, described conductor extrudes crosslinked polyetylene insulated layer outward and forms insulated wire cores, wrapped resistance to inner covering after three insulated wire cores combinations, the outer wrapped fireproof mica layer of described inner covering forms leads core, leads after core combination wrapped fireproof mica layer II, flame retardant coating, double-deck fire-retardant belting layer and external sheath layer successively for four; Lead between core for described four four control cores are set, described control core is made up of the wrapped belting layer of pair twist group, and described pair twist group extrudes crosslinked polyetylene insulated layer line core outward by pair of conductors and forms; Lead core combination center for described four and be also provided with an insulated wire cores II, described insulated wire cores II extrudes crosslinked polyetylene insulated layer line core outward by conductor and forms.
Further, described conductor structure meets the requirement of the 5th kind of conductor in GB/T 3956.
Further, described thickness of insulating layer is 0.06-0.08mm.
Further, described external sheath layer adopts halogen-free and low-smoke flame-retardant polyolefin material
The present invention adopts, at cable core, one deck flame retardant coating is set outward, and this coating can improve the self-extinguishment, hydrophobicity, sealing, insulating properties of cable etc., and this coating self adhesive force is good, fineness is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
A kind of flame retardant cable, comprise insulated wire cores, external sheath layer, outside described conductor 1, extrude crosslinked polyetylene insulated layer 2 and form insulated wire cores, wrapped resistance to inner covering 3 after three insulated wire cores combinations, the outer wrapped fireproof mica layer 4 of described inner covering 3 forms leads core, leads after core combination wrapped fireproof mica layer II 5, flame retardant coating 6, double-deck fire-retardant belting layer 7 and external sheath layer 8 successively for four; Lead between core for described four four control cores 9 are set, described control core is made up of the wrapped belting layer of pair twist group, and described pair twist group extrudes crosslinked polyetylene insulated layer line core outward by pair of conductors and forms; Lead core combination center for described four and be also provided with an insulated wire cores II 10, described insulated wire cores II extrudes crosslinked polyetylene insulated layer line core outward by conductor and forms.
Further, described conductor 1 structure meets the requirement of the 5th kind of conductor in GB/T 3956.
Further, described insulating barrier 2 thickness are 0.06-0.08mm.
Further, 8 layers of employing halogen-free and low-smoke flame-retardant polyolefin material of described oversheath
The present invention adopts, at cable core, one deck flame retardant coating is set outward, and this coating can improve the self-extinguishment, hydrophobicity, sealing, insulating properties of cable etc., and this coating self adhesive force is good, fineness is good.
Although above the specific embodiment of the present invention has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present invention and change and revise; when its function producing does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection scope of the present invention.
