Abstract
The utility model discloses an aviation high temperature resistant fireproof special cable comprising conductors formed by twisting a plurality of tined copper wire bundles; the conductors are wrapped by a FEP insulating layer so as to form an insulating wire core; three-ten groups of insulating wire cores are twisted and wrapped by a non-woven fabric so as to form a cable core; the cable core is extruded by a CPE rubber inner sheath wrapped by a braided fireproof shielding layer; the fireproof shielding layer is extruded by a specific silicon rubber outer sheath wrapped by a glass cotton tape; the glass cotton tape is wrapped by a braided tined copper wire shielding protection layer. The aviation high temperature resistant fireproof special cable can still normally work under high temperature and fire hazard condition; when fire happens, the cable can continuously and normally work, thereby providing longer time for escape and rescue.
Description
Technical field
The utility model belongs to electric wire field, is specifically related to a kind of Aero-Space fire resistant special cable.
Background technology
Aero-Space industry is the grand strategy industry of national economy, as the electric wire cable of Aero-Space nerve and blood vessel, is directly connected to fail safe, reliability, advance and the fight capability of aerospace vehicle.Along with developing rapidly of China's national defense modernization construction, improve aerospace vehicle power supply, control system safely etc. the measure of aspect will be directly connected to aerospace vehicle vitality.How research improves Aero-Space fire resistant cable performance, with reduce Aero-Space by the manufacturing cost of fire resistant, expand the applicable scope of fire resistant for Aero-Space, this still can keep ship survivability effective guarantee personnel's safety to have important realistic meaning in aerospace vehicle during in hot conditions.
Utility model content
For overcoming the defect of prior art, the purpose of this utility model is to provide a kind of Aero-Space fire resistant special cable, and this cable is to be specifically designed to deal with under high temperature and fire condition, still can provide normal work and the cable produced.When fire occurs, cable can guarantee that circuit works on, for time of more growing is striven in escape and rescue.
Scheme of the present utility model is as follows: a kind of Aero-Space fire resistant special cable, comprise by multiply tinned wird bundle conductor and close the conductor forming, at described conductor, be coated with perfluoroethylene-propylene insulating barrier and form insulated wire cores, after 3-10 group insulated wire cores pair twist, wrapped nonwoven fabrics becomes cable core, described cable core extrudes inner sheath described in chlorinated polyethylene rubber inner sheath outward and weaves fire-proof shield layer outward, fire-proof shield layer extrudes special silicone rubber oversheath outward, the outer wrapped glass strap of silicon rubber oversheath, described glass strap outer braid tinned wird shielding protection layer.
Further, described tinned wird is closed and is formed by multiply tin-coated copper tow.
Further, described insulated wire cores is three groups.
Further, the fire-proof shield layer of described fire resistant special cable is quartz fibre fire-proof shield layer.
Aero-Space of the present utility model are with fire resistant special cable because insulating layer material adopts perfluoroethylene-propylene, and sheath material is special silicone rubber, and fireprotection layer is quartz fibre fire-proof shield layer.This cable is to be specifically designed to deal with under high temperature and fire condition, still can provide normal work and the cable produced.When fire occurs, cable can guarantee that circuit works on, for time of more growing is striven in escape and rescue.
Accompanying drawing explanation

Number in the figure: 1 conductor, 2 insulating barriers, 3 nonwoven fabrics, 4 inner sheaths, 5 fire-proof shield layers, 6 silicon rubber oversheaths, 7 glass straps, 8 tinned wird shielding protection layers.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
A kind of Aero-Space fire resistant special cable, comprise by multiply tinned wird bundle conductor and close the conductor 1 forming, at described conductor 1, be coated with perfluoroethylene-propylene insulating barrier 2 and form insulated wire cores, 3 one-tenth cable cores of wrapped nonwoven fabrics after 3-10 group insulated wire cores pair twist, described cable core extrudes chlorinated polyethylene rubber inner sheath 4 outward, the outer braiding fire-proof shield of described inner sheath 4 layer 5, the outer special silicone rubber oversheath 6 that extrudes of fire-proof shield layer 5, the outer wrapped glass strap 7 of silicon rubber oversheath 6, described glass strap 7 outer braid tinned wird shielding protection layers 8.
In concrete enforcement, described tinned wird is closed and is formed by multiply tin-coated copper tow, and described insulated wire cores is three groups, and the fire-proof shield layer 5 of described fire resistant special cable is quartz fibre fire-proof shield layer.
The cable of the present embodiment is used the stranded multiply tin-coated copper of accurate stranding machine twisted wire as conductor, at conductor external application high temperature extruder, extrude perfluoroethylene-propylene insulating barrier, after insulated wire cores pair twist, stranding wrapped nonwoven fabrics become cable core, cable core extrudes chlorinated polyethylene rubber inner sheath outward, inner sheath is used high-speed knitter braiding quartz fibre fire-proof shield layer outward, fire-proof shield layer extrudes special silicone rubber oversheath outward, its outer wrapped glass strap, glass strap outer braid tinned wird shielding protection layer, i.e. stranding
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 revise; when its function producing does not exceed spiritual that specification contains yet, all should be within protection range of the present utility model.
