Abstract
The invention relates to a light radiation-resistant high-performance transmission cable for aerospace. The transmission cable comprises insulated wire cores that are formed by conductors and insulation layers arranged outside the conductors, wherein at least one insulated wire core is arranged to form a cable core; and a braiding shielding layer coats the outside of the cable core, wherein the braiding density is no less than 80%. The provided light radiation-resistant high-performance transmission cable has the characteristics of small external diameter, light weight, high-low temperature resistance, radiation resistance, and security and reliability and is suitable for aerospace.
Description
Technical field
The invention belongs to cables manufacturing field, the transmission cable production technical field of particularly using in the transmission of a kind of signal in the aircraft such as Aeronautics and Astronautics and airborne equipment thereof and energy.
Background technology
At present, the transmission cable in the fields such as Aero-Space mainly adopts F46 insulated conductor, that this class wire insulation extrudes is thick, volume large, Heavy Weight and the easy cracking of insulating after standing outer space high energy electron irradiation aging, safety and reliability are poor.Development along with Aero-Space science and technology, requirement to indexs such as the security performance of cabling system in aircraft, resistance to irradiation and insulation property and volume weights is more and more higher, and existing F46 insulated conductor has been difficult to meet Aerospace Products to the requirement of miniaturization, lightweight, high reliability future development.
Summary of the invention
In order to solve the problem existing in prior art, the object of the invention is to provide little, lightweight, the resistance to irradiation of the required volume of a kind of Aero-Space, high-low temperature resistant, light-duty radiation hardness Aero-Space high-property transmission cable that reliability is high.
The present invention is provided with single or many insulated wire cores, and cable core arranges woven shield outward, and woven shield is coated with modified Teflon restrictive coating; It is characterized in that described insulated wire cores is by stranded multiply tinned copper wire or silver-gilt copper wire, and be arranged on described stranded multiply tinned copper wire or the composition of the modified Teflon insulating barrier outside silver-gilt copper wire; Described woven shield is tinned copper wire or the silver-gilt copper wire braid of count >=80%.
Tool of the present invention has the following advantages:
(1) external diameter is little, lightweight: conductor has adopted stranded conductor stranded with core formula, and lay configuration is stable, tight, makes the conductor diameter of same cross-sectional reduce many; Insulating barrier has adopted XL-PTFE, the ultra-thin and light specific gravity of insulation thickness.
(2) high-low temperature resistant: can use under-65 ℃～200 ℃ conditions for a long time, serviceability temperature can reach more than 280 ℃ in short-term, and can be by continuing 300 ℃, 7 hours accelerated aging tests.
(3) resistance to irradiation: owing to having adopted cross-linking type material, make cable have good fluorine stability, can resist the high ionization radiation of outer space.
(4) security reliability is high: this insulation and sheath material cohesive force be strong, it is very excellent to peel off anti-cracking performance, and longitudinal incision and friction are had to very strong resistance to resistivity, is applicable to Aero-Space and uses.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present invention.
Embodiment
The present invention is provided with seven insulated wire cores 1, the woven shield 2 that the outer setting of cable core 1 is formed by tinned copper wire or the silver-gilt copper wire braid of count >=80%, woven shield 2 is coated with high temperature resistant, resistance to irradiation, high-low temperature resistant, modified Teflon restrictive coating 3 that volume is little.
Every insulated wire cores 1 is by stranded multiply tinned copper wire or silver-gilt copper wire 11, and is arranged on stranded multiply tinned copper wire or the modified Teflon insulating barrier outside silver-gilt copper wire 11 12 forms.
Claims (1)
