Abstract
The invention discloses a fireproof and flame-retardant cable. Single-strand flexible copper wires are adopted in conductors. Two layers of mica tapes surround and wrap each conductor to form a fireproof layer, so that fire-resistant wire cores are formed. Each set of three fire-resistant wire cores is extruded by a crosslinked polyethylene insulating layer after being stranded. Two layers of mica tapes wrap each insulating layer to form a fireproof layer II, so that fireproof wire cores are formed. The six fireproof wire cores are surrounded and wrapped by a polyurethane wrapping tape layer after being stranded. A shielding layer formed by braiding aluminum-plastic composite belts and copper wires, a sheath layer, a fireproof layer III and an outer protection layer are sequentially arranged outside the wrapping tape layer. Six fireproof wire cores II are arranged among the six fireproof wire cores and are formed in the mode that the two layers of mica tapes surround and wrap each conductor to form the fireproof layer. The cable can keep excellent insulating property under the condition of high temperature combustion, and can operate continuously in high-temperature flame.
Description
technical field
The present invention 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.
summary of the invention
The invention provides a kind of fire protection flame retarding cable, in high-temp combustion situation, still can keep good insulation property at cable, can operation continuously in thermal-flame.
The solution of the present invention 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.
Cable cover(ing) of the present invention 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 present invention 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 present invention, 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 invention.
embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
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 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 amendment; 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.
