Abstract
The utility model discloses a flame-resistant cable for aviation. A conductor is formed by twisting of a plurality of nickel plating thin wires; an insulating layer formed by a ceramic silicone rubber is extruded outside the conductor so as to form an insulating wire core; two insulating wire cores are stranded and are wrapped by a polyester tape so as to form a wire core; five wire cores are integrated and are wrapped by an inner cushion layer; a tinned copper wire shielding layer is woven outside the inner cushion layer; a metal armor layer is arranged outside the shielding layer; an outer sheath layer which is formed by extrusion of the ceramic silicone rubber is arranged outside the armor layer; five insulating wire cores II are arranged among the five wire cores; and the insulating wire core II is formed by extrusion of a polyethylene insulating layer outside the conductor. The cable provided by the utility model has the properties of being resistant to high / low temperature, resistant to fire, environmentally friendly, resistant to flame, low in smoke, free of halogen, great in softness, and etc., and can adapt to different work conditions.
Description
technical field
The utility model relates to a kind of aviation flame retardant cable, belongs to technical field of electric wires and cables.
background technology
Aerospace equipment, along with the raising requirement of equipment performance, has the requirements such as volume is little, lightweight to special installation.As spacecraft electrical installation, instrument and meter connecting line, want cube little, adapt to that all kinds of adverse circumstances, ampacity are large and to bear overload capacity strong, and require cable to there is good mechanical and physical performance, electric property and lay conveniently, that cable should have is high temperature resistant, fire-resistant, environmental protection, the characteristic such as fire-retardant, soft, and safety guarantee is had relatively high expectations.But existing normal cable can not meet this requirement.
utility model content
The utility model provides one can possess high-low temperature resistant, fire-resistant, environmental protection, fire-retardant, Halogen, low cigarette, the combination property such as fire-retardant and soft, can adapt to an aviation flame retardant cable of multiple different operational environment.
Scheme of the present utility model is as follows: a kind of aviation flame retardant cable, conductor is twisted into by many nickel plating filaments, outside conductor, the ceramic SiClx rubber of extruding forms insulating barrier formation insulated wire cores, two stranded rear wrapped polyester bands of insulated wire cores form core, wrapping lining-layer after five core combinations, described inner covering weaves tinned copper wire screen outward, and described screen arranges metal armouring layer outward, and described armour arranges the external sheath layer of ceramic silicon rubber extrusion modling outward; Between five described cores, five insulated wire cores II are set, described insulated wire cores II extrudes polyethylene layer outward by conductor and forms.
Further, described conductor is chosen as the 5th class conductor that meets GB/T3956.
Further, described conductor adopts regular lay configuration, and twisted wire pitch is that between 10-16 times, the sectional area of described conductor is 0.5～2.5mm
2.
The utility model adopts the many conductors that nickel plating soft copper monofilament is twisted into, and can effectively prevent the aging catalytic action of copper conductor to insulating barrier, to ensure the useful life of insulating barrier.Meanwhile, copper wire plating nickel on surface, silver or zinc-platedly also have an oxidation that prevents conductor itself, improved the flexibility of conductor, increases the security reliability in use procedure.In the utility model, all to adopt ceramic silicon rubber be material for insulating material and sheath material, has heat resistance and fire-resistant, the softness of wide range.
brief description of the drawings
Fig. 1 is structural representation of the present utility model.
embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
A kind of aviation flame retardant cable, conductor 1 is twisted into by many nickel plating filaments, form insulating barrier 2 at the ceramic SiClx rubber of the outer extruding of conductor 1 and form insulated wire cores, two stranded rear wrapped polyester bands 3 of insulated wire cores form core, wrapping lining-layer 4 after five core combinations, the described outer braiding tinned copper wire of inner covering 4 screen 5, the outer metal armouring layer 6 that arranges of described screen 5, the outer external sheath layer 7 that the extrusion modling of ceramic silicon rubber is set of described armour 6; Between five described cores, five insulated wire cores II 8 are set, described insulated wire cores II extrudes polyethylene layer outward by 8 conductors and forms.
Described conductor 1 is chosen as the 5th class conductor that meets GB/T3956.Described conductor 1 adopts regular lay configuration, and twisted wire pitch is that between 10-16 times, the sectional area of described conductor 1 is 0.5～2.5mm
2.
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 amendment; when its function producing does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection range of the present utility model.
