Abstract
The invention discloses a self-supporting type large-power coaxial cable, including an inner conductor center supporting core, a buffer layer, a tubular inner conductor, an insulating layer, an outer conductor and an outer sheath from inside to outside. The outer conductor is formed by intertwisting supporting metal wires and outer conductor conductive single wires at intervals which are the same in number; and the outer sheath is provided with a single-line convex ridge, the height of the single-line convex ridge is not smaller than 0.5mm, and the width is not smaller than 1mm. The self-supporting type large-power coaxial cable provided by the invention has very high self-supporting performance, is small in attenuation and has a good shielding effect.
Description
Technical field
The present invention relates to electric wire field, be specifically related to a kind of from bearing type high-power coaxial cable.
Background technology
The world today is the stepped into information epoch, information has become the strategic resource of economic development and unique production factors, to combine the present information transmission system and complete information service system set up with multimedia terminals such as telecommunications network, computer, videos, become the important symbol of a country economic development level.Coaxial cable is the important kind of one in information transmission, main be used as radio transmission or receiving equipment feeder and various communication, electronic equipment machine intraconnections or be interconnected line.Coaxial cable is made up of inner conductor layer, insulating barrier, outer conductor layer and restrictive coating, inner conductor layer and the usual cross section of outer conductor layer very little, from carrying poor performance, especially when cable uses under not buried operating mode, because load-carrying properties are poor, cable own wt can make cable conductor break, and is also easily damaging tiny cable conductor when constructing simultaneously.Prior art dish adopts bracing frame to support cable; coaxial cable is protected by the form increasing bracing frame; there is certain effect; but add laid down cost and time; in addition the load-carrying properties of cable own are poor, unavoidably can because accidentally operate the problem causing the core of cable to damage in work progress.
Chinese patent " ZL201520373236.X " discloses a kind of coaxial cable, its main contents are for increase reinforced layer outward at outer conductor, improve the tensile property of whole cable to a certain extent, in laid processes, due to cable will through unwinding and rewinding around operating mode, and cable at this operating mode lower stress centrostigma at the bosom of cable point, central point is protected, and inner wire tensile property is not resolved; Owing to adding one deck or a few Rotating fields in cable, add manufacturing procedure, reduce production efficiency, the weight of cable adds simultaneously, affects installation on the one hand, adds the pressure of inner wire in load bearing process on the other hand.
Summary of the invention
In order to overcome the deficiencies in the prior art, provide a kind of have very strong from load-carrying properties, little, the shield effectiveness of decaying good from bearing type high-power coaxial cable.
For achieving the above object, the invention discloses a kind of from bearing type high-power coaxial cable, comprise conductor center load bearing core, resilient coating, tubular inner conductor, insulating barrier, outer conductor and oversheath from inside to outside; Outer conductor conducts electricity single line apart windings by the identical bearing metal silk of quantity and outer conductor and forms; Described oversheath is also provided with single line convex ridge, and the height of described single line convex ridge is not less than 0.5mm, and width is not less than 1mm.
Preferably, described load bearing core and bearing metal silk are zinc-coated wire.
Preferably, described tubular inner conductor be thin copper belt through longitudinal tubing, weld, roll strand corrugated copper tube.
Preferably, described outer conductor conduction single line is annealing copper wire, annealing copper wire is the naked annealed copper conductor meeting GB/T3956-2008 commonly used of cable or metal cladding annealed copper conductor, comprise the conductor of the multiply hard circular copper wire composition of compacting pressing or the conductor of the soft circular copper wire composition of non-multiply of pressing, preferentially select the zinc-plated soft structure conductor of 5 class.
Preferably, described insulating barrier is made up of low density polyethylene (LDPE), high density polyethylene (HDPE) or radiant crosslinked polyethylene material.
Preferably, described outer jacket is made up of polythene material.
Beneficial effect of the present invention is:
The present invention has very strong from load-carrying properties, the conductor center layer You Yigen center load bearing core of cable, and the stress point of inner wire concentrates in the load bearing core of center, and cable, in folding and unfolding winding process, protects inner wire annealing copper wire, and not frangibility; Outer conductor is wound around by outer conductor zinc-coated wire, outer conductor annealing copper wire gap simultaneously, and when carrying, cable outer conductor each several part not only uniform force, also improves the tensile property of inner wire annealing copper wire; Whole cable is full symmetrical configuration, and copper wire and zinc-coated wire have function of shielding, and inner and outer conductor is in concentric position, and electromagnetic energy is confined to propagate in the medium between internal and external conductor, and therefore have decay little, shielding properties is high; Compared with prior art do not increase new reinforcement structure, the construction of cable is simple, and the outside diameter of cable is less, conveniently lays; Adopt tubular inner conductor can save metal material, alleviate cable weight, under high-power, high frequency, due to kelvin effect, electric current is in fact just along one deck flowing that conductive surface is very thin, tubular inner conductor pipe thickness is larger than the skin depth of electric current, and its radio-frequency resistance is actually just the same with solid conductor.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the present invention further, these embodiments should be understood only be not used in for illustration of the present invention and limit the scope of the invention, after having read the present invention, the amendment of those skilled in the art to the various equivalent form of value of the present invention has all fallen within the application's claims limited range.
As shown in Figure 1, the invention provides a kind of from bearing type high-power coaxial cable, comprise conductor center load bearing core 1, resilient coating 2, tubular inner conductor 3, insulating barrier 4, outer conductor and oversheath 7 from inside to outside; Be provided with conductor center load bearing core 1 at the center of tubular inner conductor 3, but make the stress point of cable inner conductor concentrate in the load bearing core of center, cable, in folding and unfolding winding process, protects inner wire annealing copper wire, and not frangibility; Outer conductor conducts electricity single line 6 apart windings by the identical bearing metal silk of quantity 5 and outer conductor and forms, and pitch controls between 75-105mm, and winding direction is left-hand; Described oversheath 7 is also provided with single line convex ridge 8, and the height of described single line convex ridge 8 is not less than 0.5mm, and width is not less than 1mm, for the identification of cable.
Tubular inner conductor 3 adopts thin copper belt through longitudinal tubing, welds, rolls the corrugated copper tube of strand, metal material can be saved, alleviate cable weight, under high-power, high frequency, due to kelvin effect, electric current is in fact just along one deck flowing that conductive surface is very thin, tubular inner conductor pipe thickness is larger than the skin depth of electric current, and its radio-frequency resistance is actually just the same with solid conductor.
