Current fire-resisting cable is of wide application general, it is adaptable to civilian, business, industrial building, it is also possible in places such as subway, ore deposit, outdoor field, civil aviaton, large-scale exhibitions place, stadiums, national defence important base and all kinds of rank dangerous areas。
Existing flame resistant cable is generally copper core cable or mineral insulated cable, and weight is big, and rice number is short, and most oversheaths adopt flame-proof polyvinyl chloride protective cover material, and during breaking out of fire, oversheath burning can produce thick smoke, and fire resistance period is short。
Summary of the invention
It is an object of the invention to provide a kind of environment-friendly type aluminum alloy fire-resistant cable, fire resistance period length, light weight, with low cost, environmental protection。
To achieve these goals, present invention employs following technical scheme: a kind of environment-friendly type aluminum alloy fire-resistant cable, including many power lines and the lapping layer, glass fiber tape, chain armor and the external sheath layer that are set in turn in outside power line;
Described power line includes conductor and the mica tape being coated on successively outside conductor, insulating barrier, and described conductor is AA8030 aluminium alloy conductor;
Described insulating barrier is provided with color-coded band for crosslinking low-smoke flame-proof polyolefin Insulation Material and insulating barrier;
Gap between described power line and lapping layer is filled by glass fibre;
Described chain armor adopts the chain armouring of aluminum alloy strip。
Wherein, described insulating barrier is that 2 layers of Ceramic silicon rubber band overlap are wrapped, and the overlap rate of putting up is 35%~50%。
Wherein, described lapping layer is that 2 layers of Ceramic silicon rubber band overlap are wrapped, and the overlap rate of putting up is 50%~55%, and the thickness of described lapping layer is 1.5~2.0mm。
Wherein, described external sheath layer adopts low-smoke and halogen-free flame retardant polyolefin jacket to extrude。
Wherein, described glass fiber tape adopts 2 layers of glass fiber tape to carry out wrapped。
The beneficial effects of the present invention is: after adopting above-mentioned cable, conductor adopts aluminum alloy materials, lower in cost, lightweight, conductor outer cladding mica tape, and power line is carried out wrapped as lapping layer by ceramic rubber strip, and fire resistance is high;Chain armor can reduce cost, adopts ep-type material, is significantly better than traditional inorganic combustion inhibitor, long service life。
Accompanying drawing explanation
In order to be illustrated more clearly that embodiment of the present invention technical scheme, below the accompanying drawing used required during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only that the present invention is in order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below the accompanying drawing used required in p-embodiment or description of the prior art is briefly described, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings。
Fig. 1 is the cross-sectional structure schematic diagram of the present invention。
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments。Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention。
Environment-friendly type aluminum alloy fire-resistant cable as shown in Figure 1, including many power lines and the lapping layer 5, glass fiber tape 6, chain armor 7 and the external sheath layer 8 that are set in turn in outside power line;Described power line includes conductor 1 and the mica tape 2 being coated on successively outside conductor 1, insulating barrier 3。
The conductor 1 of this cable is outer adopts mica tape 2 to carry out wrapped, and refractory temperature can reach 700~800 DEG C;Adopt ceramic rubber strip to carry out wrapped as lapping layer 5 to conductor 1, conductor 1 can be protected when breaking out of fire, it is prevented that conductor 1 is caused damage by fire;This cable can stand the flame-retardant test of 90min at 750 DEG C~800 DEG C, reaches fire-retardant IA level, fire-resistant I level, is applicable to the place that security against fire rank is higher。
