Abstract

The invention discloses a kind of high-power phase-compensated cable, the center of cable is provided with the conductor that multiply silver-coated copper wire is stranded, at the outer wrapped one layer of solid-core polyfluortetraethyleinsulating thin film of conductor, at the outer wrapped multilayer polytetrafluoroethylarticles micropore band of solid-core polyfluortetraethyleinsulating thin film, it is wound around silver-plated copper strips at multilayer polytetrafluoroethylarticles micropore band outer layer, outside silver-plated copper strips outer conductor, weave one layer of silver-plated copper strips screen layer, outside silver-plated copper strips screen layer, extrude perfluoroethylene-propylene restrictive coating.The present invention, while meeting other electrical property and mechanical performance index requirement, also has the ability of transmission high-frequency high-power.

Description

A kind of high-power phase-compensated cable
Technical field
The present invention relates to the electric wire in the industrial circles such as aviation, electronics, weapons, naval vessel, a kind of high-power phase-compensated cable.
Background technology
Cable is typically often to be organized the cable of at least two stranded similar ropes, often mutually insulated between group wire by several or several groups of wires, and is often twisted into round a center, and whole outside is surrounded by the cover layer of high-insulation.Cable has power cable, controls cable, compensating cable, shielded cable, high-temperature cable, computer cable, signal cable, coaxial cable, fire-resisting cable, cable for ship, aluminium alloy cable etc..They are all made up of sub-thread or stranded conductor and insulating barrier, are used for connecting circuit, electrical equipment etc..
Summary of the invention
Patent of the present invention provides a kind of high-power phase-compensated cable, while meeting other electrical property and mechanical performance index requirement, also has the ability of transmission high-frequency high-power.
The solution of the present invention is as follows: a kind of high-power phase-compensated cable, the center of cable is provided with the conductor that multiply silver-coated copper wire is stranded, at the outer wrapped one layer of solid-core polyfluortetraethyleinsulating thin film of conductor, at the outer wrapped multilayer polytetrafluoroethylarticles micropore band of solid-core polyfluortetraethyleinsulating thin film, it is wound around silver-plated copper strips at multilayer polytetrafluoroethylarticles micropore band outer layer, outside silver-plated copper strips, weave one layer of silver-plated copper strips screen layer, outside silver-plated copper strips screen layer, extrude perfluoroethylene-propylene restrictive coating.
Beneficial effects of the present invention:
1, high-frequency high-power can be transmitted: by using the big silver-plated twisted wire of specification multiply as inner wire and to use solid-core polyfluortetraethyleinsulating thin film and the wrapped compound inslation of micropore band.Calculated by design, control the effective dielectric constant of cable so that cable transmission power reaches 2000W (1GHz), far above the 500W (1GHz) of common phase-compensated cable.
2, mechanical phase is good: uses thicker silver-plated flat copper band to be wound around and weaves the composite barrier structure of silver-plated copper strips, by improving wrapped tension force and knitting tension when wrapped copper strips and braiding copper strips, make can closely be coated with between solid-core polyfluortetraethyleinsulating thin film and the wrapped compound inslation of micropore band and big specification inner wire, when bending, relative displacement is less likely to occur, thus ensure that the mechanical phase of cable, cable bends phase controlling at 1 GHz ± 6.
3, operating temperature range width: on material selects, inner wire uses multiply silver-plated copper stranded wire, insulation to use the teflin tape of heatproof 250 DEG C, and outer conductor uses silver-plated flat copper band, screen layer uses silver-plated copper strips, and sheath uses the Meltability polytetrafluorethyletubular of heatproof 300 DEG C.Cable all uses exotic material, and cable life-time service temperature, at-65-250 DEG C, improves the use ambient temperature range of cable, is suitable to use in adverse circumstances.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Label in figure: 1 conductor, 2 polytetrafluoroethylene films, 3 politef micropore bands, 4 silver-plated copper strips, 5 silver-plated copper strips screen layers, 6 perfluoroethylene-propylene restrictive coatings.
Detailed description of the invention
The present invention will be further described below in conjunction with the accompanying drawings.
Conductor 1 outer layer wrapped solid-core polyfluortetraethyleinsulating thin film 2 that the present invention is constituted at multiply silver-plated copper stranded wire and multilayer polytetrafluoroethylarticles micropore band 3 are as insulating barrier, and the rate of putting up of its band controls 48%~49.5%, the most wrapped to predetermined outside diameter;Outside politef micropore band, it is wound around the silver-plated copper strips 4 outer conductor as cable, outside outer conductor, weaves silver-plated copper strips screen layer 5;Meltability polytetrafluorethyletubular restrictive coating 6, final finished is extruded at silver-plated copper strips screen layer 5.
The silver-plated copper cabling radical of the conductor of the present invention is more than 37, and uses regular stranded form.
Although the detailed description of the invention to the present invention gives detailed description and explanation above; but it should be noted that; we can carry out various equivalence according to the conception of the present invention to above-mentioned embodiment and change and amendment; function produced by it still without departing from description contained spiritual time, all should be within protection scope of the present invention.
