Abstract
The invention discloses a high-temperature-resistant fireproof special cable used for aerospace. The cable comprises conductors formed by bundling multiple tinned copper wires, the conductors are wrapped with tetrafluoroethylene-hexafluoropropylene copolymer insulated layers to form insulated wire cores, three to ten sets of insulated wire cores are twined and then wrapped with non-woven fabrics to form a cable core, a chlorinated polyethylene rubber inner sheath is formed outside the cable core in an extruded mode, a fireproof shielding layer is woven outside the inner sheath, a special silicone rubber outer sheath is formed outside the fireproof shielding layer in an extruded mode, a glass woven band is wound on the outside of the silicone rubber outer sheath, and a tinned copper wire shielding protection layer is woven on the outer layer of the glass woven band. The cable is specially used for guaranteeing normal work on the condition of a high temperature or a fire. When the fire breaks out, the cable can guarantee that circuits continue to work, and longer time is available for escaping and rescuing.
Description
Technical field
The invention belongs to electric wire field, be 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, reducing the Aero-Space manufacturing cost of fire resistant, expand the applicable scope of Aero-Space fire resistant, this still can keep ship survivability effective guarantee personnel's safety to have important realistic meaning in aerospace vehicle during in hot conditions.
Summary of the invention
For overcoming the defect of prior art, the object of the present invention is to provide a kind of Aero-Space fire resistant special cable, 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.In the time that fire occurs, cable can ensure that circuit works on, for time of more growing is striven in escape and rescue.
The solution of the present invention is as follows: a kind of Aero-Space fire resistant special cable, comprise by multiply tinned wird bundle conductor and close the conductor forming, be coated with perfluoroethylene-propylene insulating barrier at described conductor 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 invention 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.In the time that fire occurs, cable can ensure that circuit works on, for time of more growing is striven in escape and rescue.
Brief description of the drawings

Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
A kind of Aero-Space fire resistant special cable, comprise by multiply tinned wird bundle conductor and close the conductor 1 forming, be coated with perfluoroethylene-propylene insulating barrier 2 at described conductor 1 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 uses the stranded multiply tin-coated copper of accurate stranding machine twisted wire as conductor, extrude perfluoroethylene-propylene insulating barrier at conductor external application high temperature extruder, after insulated wire cores pair twist, stranding wrapped nonwoven fabrics become cable core, cable core extrudes chlorinated polyethylene rubber inner sheath outward, inner sheath uses 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 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 contains yet, all should be within protection scope of the present invention.
