Abstract
The utility model discloses a kind of fire-resistant control flexible cable, comprise many conductors, many conductors are all coated with perfluoroethylene-propylene insulating barrier outward and form many insulated wire cores, the many mutual stranded bunchys of insulated wire cores form cable core, and cable core is provided with nonwoven fabrics lapping layer outward successively, extrusion moulding has flame resistance polyurethane elastomer sheathing layer, asbestos yarn lapping layer, Mica tape layer, aramid fiber yarn braid, nickel plating annealed copper wire braid.The utility model master is applicable to the connection that satellite ground transmitting, signal transmission, vehicle-mounted, electric equipment and instrument and meter circuit control etc., there is good fire-resistant, high temperature resistant, cold-resistant, decay resistance, meet the supporting needs of field control system such as space flight and aviation completely.
Description
technical field:
The utility model relates to space flight and aviation cable, relates in particular to a kind of fire-resistant control flexible cable.
background technology:
Along with scientific and technological high speed development, it is more and more that some are applied to electric wires of particular surroundings, the high-low temperature resistant of traditional product, softness, etc. requirement can not meet high-end special installation user demand completely.
At present, the control cables that has a good fire-resistant fire protecting performance is with a wide range of applications in fields such as space flight and aviation.
The fireproof cable that the research and development of domestic existing manufacturer are produced, its structure is mostly to be extruded one deck low smoke and zero halogen fireproof or adds fire-retardant filler etc.
The kind of existing fireproof electric wire and cable cannot meet the supporting needs of field control system such as space flight and aviation completely, in order to meet the demand in market, just need to research and develop a kind of brand-new structural design and novel fire proofing material, therefore fire-resistant, high temperature resistant, cold-resistant, corrosion-resistant flexible cable series of products be developed.
utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of fire-resistant control flexible cable, main be applicable to connection that satellite ground transmitting, signal transmission, vehicle-mounted, electric equipment and instrument and meter circuit control etc., there is good fire-resistant, high temperature resistant, cold-resistant, decay resistance.
The technical solution of the utility model is as follows:
Fire-resistant control flexible cable, comprise many conductors, it is characterized in that: many described conductors are all coated with perfluoroethylene-propylene insulating barrier outward and form many insulated wire cores, the many mutual stranded bunchys of insulated wire cores form cable core, and cable core is provided with nonwoven fabrics lapping layer outward successively, extrusion moulding has flame resistance polyurethane elastomer sheathing layer, asbestos yarn lapping layer, Mica tape layer, aramid fiber yarn braid, nickel plating annealed copper wire braid.
Described fire-resistant control flexible cable, is characterized in that: described many conductors adopt by multiply tin annealed copper wire and strandedly form through restrainting.
The utility model has the advantages that:
1, conductor adopts the tin annealed copper wire that solderability is good, resistance to corrosion is strong, for the very thin monofilament of conductor employing of heavy in section area, first restraints the method for twisting afterwards and processes, not only soft but also structure rounding, stable.
2, high temperature resistant perfluoroethylene-propylene (FEP) material is used in insulation, and this material has the chemical stability that the high low temperature scope of application is wide, excellent, high electrical insulating property and resistance to weathering can be that other various engineering plastics are incomparable.
3, sheath has been selected high strength, water-fast, salt spray resistance, low temperature resistant, soft flame resistance polyurethane elastomer, this material can meet under the environment of salt fog, humidity or mechanical damage, keep properties of product to satisfy the demands, guarantee the product quality under particular surroundings.
4, wrapped material is respectively asbestos yarn and mica tape, heat-resisting except having, anticorrosion, acidproof, the alkaline-resisting feature of asbestos yarn, also has fabulous heat insulation, fire protecting performance; Mica tape is a kind of good refractory insulating material, and resistance to elevated temperatures is good, in the time of 1000 ℃, still can keep its performance, is not melted, and is applicable to the refractory insulating layer of various fire-resisting cables.
5, braided material adopts aramid fiber yarn and nickel plating annealed copper wire, and that aramid fiber yarn has is lightweight, good insulation preformance, anti-aging, life cycle long, the premium properties such as acidproof, alkaline-resisting and high temperature resistant; Outermost nickel plating annealed copper wire has certain mechanical protection effect to cable internal layer, also has fabulous shield effectiveness simultaneously.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
embodiment:
Referring to accompanying drawing (cable is series of products, take 24 cores as example in accompanying drawing):
Fire-resistant control flexible cable, comprise many conductors, many conductors are all coated with perfluoroethylene-propylene insulating barrier outward and form many insulated wire cores 1, the many mutual stranded bunchys of insulated wire cores 1 form cable core, and cable core is provided with nonwoven fabrics lapping layer 2 outward successively, extrusion moulding has flame resistance polyurethane elastomer sheathing layer 3, asbestos yarn lapping layer 4, Mica tape layer 5, aramid fiber yarn braid 6, nickel plating annealed copper wire braid 7.
Many conductors adopt by multiply tin annealed copper wire and strandedly form through restrainting.
