Abstract
The utility model discloses a high-temperature and high-voltage soft aeronautical wire, which comprises a conductor, an inner insulating layer and an external insulating layer, wherein the conductor is composed of 7 strands of conductors, with each strand of conductor being formed by intertwisting 37 silver-plated copper wires having a silver plating thickness of 0.3mm; the inner insulating layer, which employs silicone rubber as material and has a thickness of 0.8mm and has a transparent color, is wrapped outside the 7 strands of conductors; and the external insulating layer, which employs the silicone rubber as material and has a thickness of 1.2mm and has an orange or brown color, is wrapped outside the inner insulating layer.
Description
Technical field
The utility model is applicable to aeronautical technology, is the soft aviation lead of the supporting HTHP of civil aviation engine.
Technical background
In traditional high-voltage conducting wires design, insulating barrier is at first selected the powerful material of breakdown field for use, then in the method for selecting to increase insulation thickness, guarantee lead operate as normal in the environment of HTHP, but adopt that two kinds of above methods are difficult to satisfy that volume is little, in light weight, high temperature, high pressure and soft requirement.In order to satisfy user's instructions for use, carried out multi-argument from selection, structural design to technology controlling and process, a therefrom preferred cover optimal design scheme is carried out the development of the soft light aircraft lead of HTHP.
The content of utility model
The utility model provides a kind of, HTHP soft aviation lead that highly reliable service, nontoxic, environmental protection, good bandability in rugged environment be provided stable for the supporting saving space of aero-engine, weight reduction, high-low temperature resistant, electric strength height, electrical insulation capability.
The utility model technical solution problem provides following scheme:
The soft aviation lead of a kind of HTHP, comprise conductor, inner insulating layer and external insulation layer, per share to be that the 0.3mm silver-coated copper wire is stranded by 37 silver-plated thickness form described conductor by 7 strands, described 7 strands of conductor outer wrapping one deck inner insulating layers, and described inner insulating layer material adopts silicon rubber, thickness of insulating layer is 0.8mm, color is transparent, described inner insulating layer outer wrapping one deck external insulation layer, and described external insulation layer material adopts silicon rubber, insulating barrier is thickness 1.2mm, and color is orange or brown.
The beneficial effect of this real utility model:
1, the silver-coated copper wire selected for use of conductor strandedly has good flexibility, good conductivity and thermal conductivity, corrosion-resistant and non-oxidizability, chemical property is very stable, transmission quality is high and solderability is good, has satisfied flexibility, high-low temperature resistant, has guaranteed communication quality.
2,, thermal endurance soft, nontoxic, in light weight and cold resistance in order to satisfy, stable electrical insulation capability, silicon rubber is adopted in insulation, add and adopt man-hour bilayer to extrude internal layer with white, improved disruptive field intensity, bilayer is extruded and has also been remedied the defective that individual layer extrudes and improved electric strength simultaneously, and this lead can bear test voltage DC:24kV.Individual layer extrudes the insulation external diameter 60% if bear insulation external diameter that same voltage bilayer extrudes and be, weight saving 40%.
3, increase the new varieties of the soft aviation lead of the supporting HTHP of civil aviation engine, enlarged user's range of choice.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Referring to accompanying drawing, the soft aviation lead of a kind of HTHP comprises conductor 1, inner insulating layer 2 and external insulation layer 3, and conductor 1 is per share by 37 stranded forming of 0.3mm silver-coated copper wire by 7 strands, at conductor outer wrapping one deck inner insulating layer 2, the material of inner insulating layer 2 adopts silicon rubber, thickness 0.8mm, and color is transparent, at inner insulating layer 2 outer wrapping one deck external insulation layers 3, the material of external insulation layer 3 adopts silicon rubber, thickness 1.2mm, and color is orange or brown.
