The integral body of the cable is fully symmetrical; copper wires and galvanizing steel wires have shielding functions; the inner conductor and the outer conductor are in concentric position; the electromagnetic energy is limited in a medium between the inner conductor and the outer conductor for propagation, therefore, the attenuation is small and the shielding property is high.
Description
Technical field
The present invention relates to electric wire field, be specifically related to a kind of from carrying Anti-pressure high-power coaxial composite 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, crushing resistance, decay little, shield effectiveness good, can play simultaneously signal transmission and control action from bearing type Anti-pressure high-power coaxial composite cable.
For achieving the above object, the invention discloses a kind of from carrying Anti-pressure high-power coaxial composite cable, comprise conductor center load bearing core, the first resilient coating, tubular inner conductor, insulating barrier, outer conductor, the second resilient coating and oversheath from inside to outside; Outer conductor combines by controlling insulated wire cores with at least one again after many outer conductors conduction single line apart windings; Metal compression tube is provided with between the second resilient coating and oversheath; 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 conductor center load bearing core is zinc-coated wire.
Preferably, described tubular inner conductor be thin copper belt through longitudinal tubing, weld, roll strand corrugated copper tube.
Preferably, described control insulated wire cores is by controlling conductor and be extruded in the control insulating barrier controlled outside conductor to form.
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; Metal compression tube mechanical strength is high, compressive property good, moistureproof and good airproof performance, and embossing can improve its bending property; 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.With control conductor, signal transmission and control action can be played simultaneously; 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.
