Abstract
The utility model discloses a thermoplastic elastomer sheath aviation cable comprising conductor formed by bundling a plurality of tined copper wires; the conductor is wrapped by a PTFE propylene insulating layer so as to form an insulating wire core; a pair of insulating wire core are twisted and wrapped by a wrapping tape layer to form a cable core; three cable cores are combined and wrapped by a polyester tape; a fireproof glass fiber rope, serves as a filling layer, is arranged between the cable cores and the polyester tape; the polyester tape is wrapped by a braided tined copper wire shielding layer extruded by the polyolefin alloy thermoplastic elastomer sheath. The thermoplastic elastomer sheath aviation cable solves the problem of poor high-low temperature resistance of the cable, so the cable of the utility model has excellent high temperature resistant property, the influences to cable electric property by the temperature is reduced, thereby ensuring normal usage of the cable.
Description
Technical field
The utility model belongs to electric wire field, is specifically related to a kind of thermoplastic elastomer sheath cable for aerospace.
Background technology
Due to the particularity of Aviation cable environment for use, its cable is usually used in high low temperature operational environment, in these high low temperature operational environments, normal because cable non-refractory has influence on the electric property of cable, thereby has influence on the normal use of electric equipment.
Utility model content
For overcoming the defect of prior art, the purpose of this utility model is to provide a kind of thermoplastic elastomer sheath cable for aerospace, successfully solved the problem of cable high and low temperature resistance deficiency, make cable there is good resistance to elevated temperatures, reduced the impact of temperature on cable electrical performance, guaranteed that it normally uses.
The following a kind of thermoplastic elastomer sheath cable for aerospace of scheme of the present utility model, comprise by multiply tinned wird conductor bundle close and conductor, at described conductor, be coated with polytetrafluoroethyl-ne propylene insulating barrier and form insulated wire cores, after a pair of insulated wire cores pair twist, coated belting layer becomes cable core, outer wrapped polyester belt after three cable core combinations, is provided with flame retardant type glass cord as packed layer between cable core and polyester belt; Described polyester belt weaves tinned wird screen outward, the outer extruded polyolefin alloy thermoplastic elastomer sheath of described tinned wird screen.
Further, the polyolefin alloy thermoplastic elastomer sheath of described high-low temperature resistant layer is coated layer of steel wire braid outward again.
Further, described tinned wird is 10-20 thigh.
Compared with prior art, perfluoroethylene-propylene insulation TPO sheath cable for aerospace of the present utility model is because insulating layer material adopts polytetrafluoroethylene, sheath material is TPO, make cable there is good high and low temperature resistance (60～150 ℃), reduced the impact of temperature on cable electrical performance, guaranteed that it normally uses.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Number in the figure, 1 conductor, 2 insulating barriers, 3 polyester belts, 4 tinned wird braids, 5 polyolefin alloy thermoplastic elastomer sheaths, 6 steel wire braids.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
A kind of thermoplastic elastomer sheath cable for aerospace, comprise by multiply tinned wird conductor bundle close and conductor 1, at described conductor 1, be coated with polytetrafluoroethyl-ne propylene insulating barrier 2 and form insulated wire cores, after a pair of insulated wire cores pair twist, coated belting layer becomes cable core, outer wrapped polyester belt 3 after three cable core combinations, is provided with flame retardant type glass cord as packed layer between cable core and polyester belt 3; The outer braiding tinned wird of described polyester belt 3 screen 4, the outer extruded polyolefin alloy of described tinned wird screen 4 thermoplastic elastomer sheath 5.
In concrete enforcement, the outer coated layer of steel wire braid 6 again of the polyolefin alloy thermoplastic elastomer sheath 5 of described high-low temperature resistant layer; Described tinned wird is 10-20 thigh.
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.
