Abstract
The utility model discloses a fireproof flame-retardant cable. A conductor adopts a single strand of soft copper wire; the conductor is wrapped with two layers of mica tapes to form a fireproof layer to form a fire-resistance core; three fire-resistance cores are stranded and a crosslinked polyethylene insulation layer is extruded; the insulation layer is wrapped with two layers of mica tapes to form a fireproof layer II to form a fireproof core; six fireproof cores are stranded and then wrapped with a polyurethane wrapping layer; a shielding layer braided by adopting an aluminum plastic compound tape and copper wire, a sheath layer, a fireproof layer III and an outer protection layer are sequentially arranged outside the wrapping layer; six fireproof cores II are also arranged among six fireproof cores; and the conductor is wrapped with two layers of mica tapes to form a fireproof layer to form each fireproof core II. The cable of the utility model can keep excellent insulation performance in the high temperature burning condition and can continuously operate in high temperature flame.
Description
technical field
The utility model relates to a kind of fire protection flame retarding cable.Belong to technical field of electric wires and cables.
background technology
Fire can burn comprehensive wiring system, and Internet Transmission is interrupted.Meanwhile, if cable produces a large amount of toxic gases and flue dust in combustion process, can produce impact greatly to personnel's escape so, even become safe hidden danger.Therefore, the engineers of various countries is all being stepped up research for data backup and the safer fireproof cable of personnel.
utility model content
The utility model provides a kind of fire protection flame retarding cable, still can keep good insulation property at cable in high-temp combustion situation, can operation continuously in thermal-flame.
Scheme of the present utility model is as follows: a kind of fire protection flame retarding cable, conductor adopts solely strand soft copper silk, on described conductor, wrapped two-layer mica tape composition fireprotection layer forms fire-resistant core, after three fire-resistant cores are stranded, extrude crosslinked polyetylene insulated layer, the described insulating barrier mica tape composition fireprotection layer II of double-baging outward forms fire prevention core; The stranded rear wrapped polyurethane belting layer of six roots of sensation fire prevention core, described belting layer sets gradually the screen, restrictive coating, fireprotection layer III, the outer jacket that adopt aluminium-plastic tape and proof copper-wire braided outward; Six roots of sensation fire prevention core II is also set between described six roots of sensation fire prevention core, and described fire prevention core II forms fireprotection layer by the outer wrapped two-layer mica tape of conductor and forms.
Further, described jacket layer adopts low smoke, zero halogen polyolefine material to extrude moulding.
Further, described outer jacket adopts thermoplasticity fire prevention polyolefin to extrude moulding.
The utility model cable cover(ing) adopts low smoke, zero halogen polyolefin jacket, has well the features such as fire-retardant, high mechanical properties due to low smoke, zero halogen polyolefin jacket.The utility model extrudes one deck thermoplastic halogen-free fire prevention polyolefin jacket material at outermost, can effectively prevent the burning of flame, improves fireproofing of cable performance.The wrapped double-layer alloy mica tape of the utility model, improves fireproofing of cable performance, extends cable useful life.Adopt aluminium-plastic tape and proof copper-wire braided shielding, there is good shielding properties and interference free performance, improved greatly the shielding properties of cable.
brief description of the drawings
Fig. 1 is structural representation of the present utility model.
embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
A kind of fire protection flame retarding cable, conductor adopts solely strand soft copper silk, on described conductor 1, wrapped two-layer mica tape composition fireprotection layer 2 forms fire-resistant core, after three fire-resistant cores are stranded, extrude crosslinked polyetylene insulated layer 3, the outer mica tape composition fireprotection layer II 4 of double-baging of described insulating barrier 3 forms fire prevention core; The stranded rear wrapped polyurethane belting layer 5 of six roots of sensation fire prevention core, the outer screen 6, restrictive coating 7, fireprotection layer III 8, the outer jacket 9 that adopt aluminium-plastic tape and proof copper-wire braided of setting gradually of described belting layer 5; Six roots of sensation fire prevention core II 10 is also set between described six roots of sensation fire prevention core, and described fire prevention core II 10 forms fireprotection layer by the outer wrapped two-layer mica tape of conductor and forms.
Described jacket layer 7 adopts low smoke, zero halogen polyolefine material to extrude moulding.Described outer jacket 9 adopts thermoplasticity fire prevention polyolefin to extrude moulding.
Although above embodiment of the present utility model 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 utility model and change and amendment; when its function producing does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection range of the present utility model.
