Description
(1) technical field
This utility model relates to field of cable technology, particularly to a kind of environment-friendlyfireproof fireproof cable.
(2) background technology
At present, the occasion that the fire safety condition such as domestic skyscraper, oil, mine, subway, tunnel is high, the cable insulation used, restrictive coating mostly adopt the insulant of Halogen. Fire, once spread, not only can produce substantial amounts of dense smoke, and the hydrogen halide that the corrosivity that can produce to have " secondary disaster " is very strong, jeopardize the life of people. Flame-retardant insulating material even with Halogen, low halogen; also flame-retardant insulating material can only be delayed to be burnt till the time of powder; if continuing to be burnt; just gradually become shed powder; lose protective effect; electric wire is easy to breakdown cause short circuit, thus being difficult to ensure communication, electric power in case of fire safe and smooth.
(3) summary of the invention
This utility model is in order to make up the deficiencies in the prior art, provide a kind of rational in infrastructure, design science, fire prevention, nontoxic, environmental protection, safety high, be suitable to remain under specific disaster scenario maintain energising, for the emergency power supplies such as disaster relief power supply, illumination, communication low smoke and zero halogen, nontoxic environmental protection fireproof cable, solve problems of the prior art.
This utility model is achieved by the following technical solution:
A kind of environment-friendlyfireproof fireproof cable, including several cable inner cores, at the outside wrapped lapping layer of cable inner core, fills a packed layer between lapping layer and cable inner core, is provided externally with a twisted shape fireprotection layer at lapping layer, is provided externally with a sheath at twisted shape fireprotection layer; Described cable inner core includes conductor wire core, and described conductor wire core is stranded conductor or bundle glue conductor, at the wrapped flame retardant coating of conductor wire core outer gap, is provided externally with an insulating barrier at flame retardant coating.
Described lapping layer is fire-retardant gluing glass cloth tape; Described packed layer is flame retardant inorganic paper string; Described twisted shape fireprotection layer is worked out with twisted shape with the chlorinated rubber containing glass fibre; Described sheath is ceramic halogen-free flameproof fireproof; Described flame retardant coating is high-quality mica tape; Described insulating barrier is 105 DEG C, 125 DEG C or 150 DEG C of low-smoke non-halogen flame-retardant irradiation crosslinked polyolefin insulating layers.
The beneficial effects of the utility model are: this environment-friendlyfireproof fireproof cable insulating barrier is on the basis of tradition fireproof cable structure, by increasing and change corresponding structure and material, design the high-quality mica tape flame retardant coating outwards set gradually by cable core, 105 DEG C, 125 DEG C or 150 DEG C of low-smoke non-halogen flame-retardant irradiation crosslinked polyolefin insulating layers, flame retardant inorganic paper string packed layer, fire-retardant gluing glass cloth tape lapping layer, chlorinated rubber twisted shape fireprotection layer containing glass fibre, ceramic halogen-free flameproof fireproof, this structural design fire prevention safety performance is higher, product can at thermal-flame, under mechanical shock effect, the ability of normal operation is still possessed within a very long time, will not spread, burning and generation harmful gas, reach the designing requirement of environment-friendlyfireproof fireproof cable.This environment-friendlyfireproof fireproof cable is changed to low-smoke non-halogen flame-retardant cross-linking radiation polyolefine material by the insulation of common flame-proof polyvinyl chloride, this crosslinking method utilizes the high-energy electron line that electron accelerator produces, bombardment insulating barrier, macromolecular chain is interrupted, each breakpoint being interrupted becomes free radical, free radical is unstable, to reconfigure each other, and chain-like molecular structure original after reconfiguring becomes three-dimensional netted molecular structure and forms crosslinking. Cable properties after irradiation: 1, current-carrying capacity increases 15%-30%; 2, long service life; 3, environmental protection, safety. The twisted shape fireprotection layer structural design arranged between lapping layer and sheath, resistance to elevated temperatures is more excellent. By common flame-proof polyvinyl chloride material, restrictive coating is changed to ceramic halogen-free flameproof fireproof, and this material is nonpoisonous and tasteless at normal temperatures, has good flexibility and elasticity and good processability. High temperature more than 500 DEG C and under flame ablation, organic principle ablated in a short period of time can change into hard ceramic-like material, form isolation layer one layer good, stop burning away of flame, and the ablation time is more long, temperature is more high, and hard effect is more obvious, it is possible to reach the fire-resistant environment of 1200-1500 DEG C. Remain without any ashes after burning simultaneously, really serve the purpose of fireproofing function and safety and environmental protection. This environment-friendlyfireproof fireproof cable is economic and environment-friendly, it is possible to reduce the cost of cable, and the processing technique of this material is simple simultaneously, produce in batches in hgher efficiency, quality is more stable.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, this utility model is further described.
Fig. 1 is this utility model structural representation.
In figure, 1 cable inner core, 2 lapping layers, 3 packed layers, 4 twisted shape fireprotection layers, 5 sheaths, 6 conductor wire cores, 7 flame retardant coatings, 8 insulating barriers.
