For realizing present configuration, effect optimization, its further measure: described insulation layer is by proportion 1.76g/cm3Cross-linked ethylene-TFE copolymer extrude on conductor, the thickness of this insulation layer is 0.10��0.15mm.
Described internal layer is the silver-plated of 1 diameter 0.12��0.37mm or tin-coated copper plated aluminium alloy circle line.
Described middle layer is that the silver-plated of 6 diameter 0.12��0.37mm or tin-coated copper plated aluminium alloy circle line also evenly carry out stranded around internal layer.
Described skin is that the silver-plated of 12 diameter 0.12��0.37mm or tin-plating round copper wire also evenly carry out stranded around middle layer.
Described proportion that is silver-plated or tin-coated copper plated aluminium alloy circle line is 3.62g/cm3��
The present invention also provides the cable of a kind of space flight and aviation, several electric wires that it comprises screen layer and is arranged in screen layer.
Described screen layer is woven by the silver-plated of thickness 0.05��0.15mm or tin-coated copper plated aluminium alloy flat wire, and knitting tightness is not less than 85%.
Electric wire in described screen layer is 1��10.
A kind of space flight and aviation electric wire of the present invention and cable, several electric wires that it comprises screen layer and is arranged in screen layer, the conductor that described electric wire comprises insulation layer and is arranged in insulation layer, this conductor is stranded with one heart and become by the internal layer arranged successively from the inside to the outside, middle layer and skin; Its utilizes the innovative material of double-deck stranded conductor structure and light specific gravity thus overcomes that existing electric wire external diameter is big and the problem such as weight is big, and one-piece construction is scientific and reasonable, install easy, shield effectiveness is good, it is convenient to processing, there is significant economic benefit and social benefit, wide market, it is convenient to promote the use of.
The useful effect that the present invention produces compared to existing technology:
I, the internal layer of the double-deck stranded conductor of the present invention and middle layer adopt silver-plated or tin-coated copper plated aluminium alloy circle line, outer adopt silver-plated or tin-plating round copper wire, and this structure makes the proportion of whole conductor be down to 6.95g/cm3, so that the weight reduction 22% of conductor in electric wire, and this structure is easy to welding processing, stable performance;
II, the insulation layer of the present invention adopts the little cross-linked ethylene-TFE copolymer material of proportion, and thickness is 0.10��0.15mm, and more general 600V level aerospace line reduces physical dimension, also mitigates weight simultaneously;
III, the insulation layer of the present invention adopts cross-linked ethylene-TFE copolymer material, it is possible to the radiation of effective anti-outer space Millikan's rays;
IV, the screen layer of the present invention adopts silver-plated or tin-coated copper plated aluminium alloy flat wire, thus the proportion making screen layer is down to 3.62g/cm3, make the weight reduction 60% of screen layer, and adopt the braiding of metal flat line to effectively reduce wire external diameter, be conducive to saving and space is installed.
The present invention is widely used in space flight and aviation coordinative composition of equipments and uses.
