Abstract
The invention discloses a reinforced compressive coaxial aerial cable, which comprises an inner conductor, an insulating layer, an outer conductor, a buffer layer and an outer sheath from the inside to the outside, wherein the inner conductor is formed by twisting a reinforcing core at the center and a plurality of single aluminum alloy wires which surround the reinforcing core by taking the reinforcing core as the circle center; the outer conductor is formed by combining a pair of bearing cores and a plurality of copper wires; the pair of bearing cores is centrosymmetric about the cable; a rigid plastic compressive pipe is arranged between the buffer layer and the outer sheath; and a temperature sensing alarm is also arranged on the outer sheath. The reinforced compressive coaxial aerial cable has high reinforcing property, self-bearing property and compressive property, good moisture resistance and air-tightness, small attenuation and good shielding effect, and simultaneously can play a temperature monitoring role.
Description
Technical field
The present invention relates to electric wire field, be specifically related to the coaxial aerial cable of a kind of reinforcement Anti-pressure.
Background technology
Coaxial aerial 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 aerial 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 adopts bracing frame to support cable, coaxial aerial 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; Prior art major part is all adopt metal compression tube to increase compressive property, and be metal due to what adopt, and other layers are plastic layer, mutually, amalgamation is poor, affects the performance of cable; In addition, most of cable is all too high by temperature, causes spontaneous combustion, causes very large loss.
Summary of the invention
In order to overcome the deficiencies in the prior art, provide a kind of have very strong from carrying and compressive property, moistureproof and good airproof performance, decay little, shield effectiveness good, can play the coaxial aerial cable of reinforcement Anti-pressure of monitoring cable temperature action simultaneously.
For achieving the above object, the invention discloses the coaxial aerial cable of a kind of reinforcement Anti-pressure, comprise inner wire, insulating barrier, outer conductor, resilient coating and oversheath from inside to outside; Described inner wire is by being positioned at the strengthening core at its center and being that the center of circle is centered around that some aluminium alloy single lines outside strengthening core are stranded to be formed with strengthening core; Outer conductor combines with the load bearing core of cable center's symmetry and some copper wires by a pair; Rigid plastics compression tube is provided with between resilient coating and oversheath; Described oversheath is also provided with temperature sense alarm, and the height of temperature sense alarm is not more than 0.5mm, and width is not more than 1mm.
Preferably, described strengthening core is steel wire rope.
Preferably, described load bearing core is by center zinc-coated wire and the plastic protective layer that is extruded in outside zinc-coated wire.
Beneficial effect of the present invention is:
1, the present invention has very strong reinforcing property and from load-carrying properties, the conductor center layer You Yigen center strengthening core of cable, and the stress point of inner wire concentrates on the strengthening core of center, and cable, in folding and unfolding winding process, protects inner wire, and not frangibility;
2, the present invention has very strong from load-carrying properties, and be provided with a pair load bearing core in the outer conductor of cable, the stress point of outer conductor concentrates in this pair load bearing core, and cable, in folding and unfolding winding process, protects outer conductor, and not frangibility;
3, the present invention adopts rigid plastics compression tube alternative metals compression tube, have that better mechanical strength is high, compressive property, protection against the tide and sealing, bending property, and plastics more can be able to merge with other layers;
4, oversheath of the present invention is also provided with temperature sense alarm, energy detection streamer variations in temperature operationally, if exceed the temperature that this cable bears, alarm will be reported to the police, staff just can cut off the electricity supply, and prevents cable to be burned, adds fail safe, avoid cable fire and the loss caused, also save cost.
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 the coaxial aerial cable of a kind of reinforcement Anti-pressure, comprise inner wire, insulating barrier 3, outer conductor, resilient coating 5 and oversheath 7 from inside to outside; Described inner wire is by being positioned at the strengthening core 1 at its center and being that the center of circle is centered around that some aluminium alloy single lines 2 outside strengthening core are stranded to be formed with strengthening core; Outer conductor combines with the load bearing core of cable center's symmetry and some copper wires 4 by a pair, described load bearing core is by center zinc-coated wire 8 and the plastic protective layer 9 that is extruded in outside zinc-coated wire 8, not only serve the effect of protection zinc-coated wire, prevent interfering with each other and rubbing between zinc-coated wire and copper wire, affect the performance of cable; Rigid plastics compression tube 6 is provided with between resilient coating 5 and oversheath 7; Described oversheath 7 is also provided with temperature sense alarm 10, the height of temperature sense alarm is not more than 0.5mm, width is not more than 1mm, can detection streamer variations in temperature operationally, the temperature that this cable bears if exceed, alarm will be reported to the police, staff just can cut off the electricity supply, and prevents cable to be burned, adds fail safe, avoid cable fire and the loss caused, also save cost.
The above is only the preferred embodiment of the present invention, it should be pointed out that for the person of ordinary skill of the art, under the premise without departing from the principles of the invention, can also make some modification and improvement, and these also should be considered as belonging to protection scope of the present invention.
