Abstract

The utility model discloses a strengthen coaxial aerial [insulated] cable of resistance to compression type includes inner conductor, insulating layer, outer conductor, buffer layer and oversheath from inside to outside, the inner conductor by lieing in its central enhancement core and using and strengthen the core as the centre of a circle around stranding and form strengthening core a plurality of outer aluminum alloy single lines, the outer conductor is formed with cable centrosymmetric hosting core and a plurality of copper wire combinations by a pair of, be equipped with rigid plastic pressure -resisting pipe between buffer layer and oversheath, the oversheath on still be equipped with the temperature -sensing alarm. The utility model discloses have very strong enhancement performance, from load -carrying properties and compressive property, dampproofing and the leakproofness is good, attenuate little, the shielding is effectual, can play the temperature effect of monitoring simultaneously.

Description

A kind of reinforcement coaxial overhead line of resistance to compression type

Technical field

The utility model relates to electric wire field, is specifically related to a kind of reinforcement coaxial overhead line of resistance to compression type.

Background technology

Coaxial overhead line is a kind of important kind during information is transmitted, main be used as transmit by radio or receiving equipment antenna feeder and various communication, the machine intraconnections of electronics or be interconnected line. Coaxial overhead line is made up of inner conductor layer, insulation layer, outer conductor layer and restrictive coating, inner conductor layer and the usual cross section of outer conductor layer are very little, from carrying poor performance, especially when cable uses under not buried operating mode, owing to 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 be supported by cable, coaxial overhead line is protected by increasing the form of 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 operation causes the problem that the core of cable damages accidentally in construction process; Prior art major part is all adopt metal compression tube to increase compressive property, is metal due to what adopt, and other layers are plastic layer, and between mutually, amalgamation is poor, affects the performance of cable; In addition, major part cable is all too high by temperature, causes spontaneous combustion, causes very big loss.

Practical novel content

In order to overcome the deficiencies in the prior art, it is provided that a kind of have very strong from carrying and compressive property, moistureproof and good airproof performance, decay little, shield effectiveness good, can play the reinforcement coaxial overhead line of resistance to compression type of monitoring cable temperature effect simultaneously.

For achieving the above object, the utility model discloses a kind of reinforcement coaxial overhead line of resistance to compression type, comprise interior conductor, insulation layer, outer conductor, buffer layer and oversheath from inside to outside; Described interior conductor by be positioned at the strengthening core at its center and taking strengthening core be some aluminium alloy single lines that the center of circle is centered around outside strengthening core stranded become; Outer conductor combines with the load bearing core of cable center's symmetry and some copper wires by one; Rigid plastics compression tube it is provided with between buffer layer and oversheath; Also being provided with temperature induction alarm device on described oversheath, the height of temperature induction alarm device is not more than 0.5mm, and width is not more than 1mm.

Preferably, described strengthening core is wireline.

Preferably, described load bearing core is by center galvanized steel wire and the plastic protective layer that is extruded in outside galvanized steel wire.

The beneficial effects of the utility model are:

1, the utility model has very strong reinforcement performance and from load-carrying properties, the conductor center layer You Yigen center strengthening core of cable, interior conductor concentrate on the strengthening core of center by force, cable is in folding and unfolding winding process, protect interior conductor, and not frangibility;

2, the utility model has very strong from load-carrying properties, is provided with one pair of load bearing core in the outer conductor of cable, outer conductor concentrate on this to, in load bearing core, cable, in folding and unfolding winding process, protects outer conductor by force, and not frangibility;

3, the utility model adopts rigid plastics compression tube alternative metals compression tube, has better physical strength height, compressive property, protection against the tide and stopping property, bending property, and plastics more can be able to merge with other layers;

4, the utility model oversheath is also provided with temperature induction alarm device, energy detection streamer temperature variation operationally, if exceeding the temperature that this cable bears, warning howler will be reported to the police, staff just can cut off the electricity supply, and prevents cable to be burned, adds security, the loss avoiding cable burning and cause, also saves cost.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Embodiment

Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, these embodiments should be understood and only it is not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of the various equivalent form of value of the present utility model is all fallen within the application's claims limited range by those skilled in the art.

As shown in Figure 1, the utility model provides a kind of and strengthens the coaxial overhead line of resistance to compression type, comprises interior conductor, insulation layer 3, outer conductor, buffer layer 5 and oversheath 7 from inside to outside; Described interior conductor by be positioned at the strengthening core 1 at its center and taking strengthening core be some aluminium alloy single lines 2 that the center of circle is centered around outside strengthening core stranded become; Outer conductor combines with the load bearing core of cable center's symmetry and some copper wires 4 by one, described load bearing core is by center galvanized steel wire 8 and the plastic protective layer 9 that is extruded in outside galvanized steel wire 8, not only serve the effect of protection galvanized steel wire, prevent interfering with each other and rubbing between galvanized steel wire and copper wire, affect the performance of cable; Rigid plastics compression tube 6 it is provided with between buffer layer 5 and oversheath 7; Described oversheath 7 is also provided with temperature induction alarm device 10, the height of temperature induction alarm device is not more than 0.5mm, width is not more than 1mm, and energy detection streamer temperature variation operationally, if exceeding the temperature that this cable bears, warning howler will be reported to the police, staff just can cut off the electricity supply, and prevents cable to be burned, adds security, the loss avoiding cable burning and cause, also saves cost.

The above is only preferred implementation of the present utility model; it is noted that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model principle; can also making some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
